Golden Gate step by step Implementation notes

Step By Step Golden Gate Configuration Step By Step Golden Gate Configuration: GoldenGate enables us to extract and replicate data across a variety of topologies as shown the diagram below as well as the exchange and manipulation of data at the transactional level between a variety of database platforms like Oracle, DB2, SQL Server, Ingres, MySQL etc. It can support a number of different business requirements like:  Business Continuity and High Availability  Data migrations and upgrades  Decision Support Systems and Data Warehousing  Data integration and consolidation

Manager The Manager process must be running on both the source as well as target systems before the Extract or Replicat process can be started and performs a number of functions including monitoring and starting other GoldenGate processes, managing the trail files and also reporting. Extract The Extract process runs on the source system and is the data capture mechanism of GoldenGate. It can be configured both for initial loading of the source data as well as to synchronize the changed data on the source with the target. This can be configured to also propagate any DDL changes on those databases where DDL change support is available. Replicat The Replicat process runs on the target system and reads transactional data changes as well as DDL changes and replicates then to the target database. Like the Extract process, the Replicat process can also be configured for Initial Load as well as Change Synchronization. Collector The Collector is a background process which runs on the target system and is started automatically by the Manager (Dynamic Collector) or it can be configured to stsrt manually (Static Collector). It receives extracted data changes that are sent via TCP/IP and writes then to the trail files from where they are processed by the Replicat process. Trails Trails are series of files that GoldenGate temporarily stores on disks and these files are written to and read from by the Extract and Replicat processes as the case may be. Depending on the configuration chosen, these trail files can exist on the source as well as on the target systems. If it exists on the local system, it will be known an Extract Trail or as an Remote Trail if it exists on the target system. Data Pumps Data Pumps are secondary extract mechanisms which exist in the source configuration. This is optional component and if Data Pump is not used then Extract sends data via TCP/IP to the remote trail on the target. When Data Pump is configured, the Primary Extract process will write to the Local Trail and then this trail is read by the Data Pump and data is sent over the network to Remote Trails on the target system. In the absence of Data Pump, the data that the Extract process extracts resides in memory alone and there is no storage of this data anywhere on the source system. In case of network of target failures, there could be cases where the primary extract process can abort or abend. Data Pump can also be useful in those cases where we are doing complex filtering and transformation of data as well as when we are consolidating data from many sources to a central target. Data source When processing transactional data changes, the Extract process can obtain data directly from the database transaction logs (Oracle, DB2, SQL Server, MySQL etc) or from a GoldenGate Vendor Access Module (VAM) where the database vendor (for example Teradata) will provide the required components that will be used by Extract to extract the data changes. Groups To differentiate between the number of different Extract and Replicat groups which can potentially co-exist on a system, we can define processing groups. For instance, if we want to replicate different sets of data in parallel, we can create two Replicat groups. A processing group consists of a process which could be either a Extract or Replicat process, a corresponding parameter file, checkpoint file or checkpoint table (for Replicat) and other files which could be associated with the process.

ORA-00000 to ORA-00851

ORA-00000 to ORA-00851
ORA-00000: normal, successful completion
Cause: Normal exit.
Action: None
ORA-00001: unique constraint (string.string) violated
Cause: An UPDATE or INSERT statement attempted to insert a duplicate key. For Trusted Oracle configured in DBMS MAC mode, you may see this message if a duplicate entry exists at a different level.
Action: Either remove the unique restriction or do not insert the key.
ORA-00017: session requested to set trace event
Cause: The current session was requested to set a trace event by another session.
Action: This is used internally; no action is required.
ORA-00018: maximum number of sessions exceeded
Cause: All session state objects are in use.
Action: Increase the value of the SESSIONS initialization parameter.
ORA-00019: maximum number of session licenses exceeded
Cause: All licenses are in use.
Action: Increase the value of the LICENSE MAX SESSIONS initialization parameter.
ORA-00020: maximum number of processes (string) exceeded
Cause: All process state objects are in use.
Action: Increase the value of the PROCESSES initialization parameter.
ORA-00021: session attached to some other process; cannot switch session
Cause: The user session is currently used by others.
Action: Do not switch to a session attached to some other process.
ORA-00022: invalid session ID; access denied
Cause: Either the session specified does not exist or the caller does not have the privilege to access it.
Action: Specify a valid session ID that you have privilege to access, that is either you own it or you have the CHANGE_USER privilege.
ORA-00023: session references process private memory; cannot detach session
Cause: An attempt was made to detach the current session when it contains references to process private memory.
Action: A session may contain references to process memory (PGA) if it has an open network connection, a very large context area, or operating system privileges. To allow the detach, it may be necessary to close the session's database links and/or cursors. Detaching a session with operating system privileges is always disallowed.
ORA-00024: logins from more than one process not allowed in single-process mode
Cause: Trying to login more than once from different processes for ORACLE started in single-process mode.
Action: Logoff from the other process.
ORA-00025: failed to allocate string
Cause: Out of memory.
Action: Restart with larger sga heap.
ORA-00026: missing or invalid session ID
Cause: Missing or invalid session ID string for ALTER SYSTEM KILL SESSION.
Action: Retry with a valid session ID.
ORA-00027: cannot kill current session
Cause: Attempted to use ALTER SYSTEM KILL SESSION to kill the current session.
Action: None
ORA-00028: your session has been killed
Cause: A privileged user has killed your session and you are no longer logged on to the database.
Action: Login again if you wish to continue working.
ORA-00029: session is not a user session
Cause: The session ID specified in an ALTER SYSTEM KILL SESSION command was not a user session (for example, recursive, etc.).
Action: Retry with a user session ID.
ORA-00030: User session ID does not exist.
Cause: The user session ID no longer exists, probably because the session was logged out.
Action: Use a valid session ID.
ORA-00031: session marked for kill
Cause: The session specified in an ALTER SYSTEM KILL SESSION command cannot be killed immediately (because it is rolling back or blocked on a network operation), but it has been marked for kill. This means it will be killed as soon as possible after its current uninterruptable operation is done.
Action: No action is required for the session to be killed, but further executions of the ALTER SYSTEM KILL SESSION command on this session may cause the session to be killed sooner.
ORA-00032: invalid session migration password
Cause: The session migration password specified in a session creation call was invalid (probably too long).
Action: Retry with a valid password (less than 30 chars).
ORA-00033: current session has empty migration password
Cause: An attempt was made to detach or clone the current session and it has an empty migration password. This is not allowed.
Action: Create the session with a non-empty migration password.
ORA-00034: cannot string in current PL/SQL session
Cause: An attempt was made to issue a commit or rollback from a PL/SQL object (procedure, function, package) in a session that has this disabled (by 'alter session disable commit in procedure')
Action: Enable commits from PL/SQL in this session, or do not attempt to use commit or rollback in PL/SQL when they are disabled in the current session.
ORA-00036: maximum number of recursive SQL levels (string) exceeded
Cause: An attempt was made to go more than the specified number of recursive SQL levels.
Action: Remove the recursive SQL, possibly a recursive trigger.
ORA-00037: cannot switch to a session belonging to a different server group
Cause: An attempt was made to switch to a session in a different server group. This is not allowed.
Action: Make sure the server switches to a session that belongs to its server group.
ORA-00038: Cannot create session: server group belongs to another user
Cause: An attempt was made to create a non-migratable session in a server group that is owned by a different user.
Action: A server group is owned by the first user who logs into a server in the server group in non-migratable mode. All subsequent non-migratable mode logins must be made by the user who owns the server group. To have a different user login in non-migratable mode, the ownership of the server group will have to be changed. This can be done by logging off all current sessions and detaching from all existing servers in the server group and then having the new user login to become the new owner.
ORA-00039: error during periodic action
Cause: An unexpected error occurred while executing a periodically invoked
Action: Check the error stack for detailed error information.
ORA-00040: active time limit exceeded - call aborted
Cause: The Resource Manager SWITCH_TIME limit was exceeded.

Action: Use a valid service name from SERVICE$ or add a new service using the DBMS_SERVICE package.
ORA-00043: remote operation failed
Cause: Execution of the inter-instance operation failed.
Action: Check the status of the target instance. The operation may have partially executed. Verify the result of the intended operation.
ORA-00044: timed_statistics must be TRUE when statistics_level is not BASIC
Cause: The user attempted to set timed_statistics to FALSE when statistics_level was not BASIC. timed_statistics is required to be TRUE to collect meaningful statistics when statistics_level is set to TYPICAL or ALL.
Action: Either set timed_statistics to TRUE or set statistics_level to BASIC.
ORA-00050: operating system error occurred while obtaining an enqueue
Cause: Could not obtain the operating system resources necessary to cover an oracle enqueue. This is normally the result of an operating system user quota that is too low.
Action: Look up the operating system error in your system documentation and perform the needed action.
ORA-00051: timeout occurred while waiting for a resource
Cause: Usually due to a dead instance.
Action: Check for any dead, unrecovered instances and recover them.
ORA-00052: maximum number of enqueue resources (string) exceeded
Cause: Ran out of enqueue resources.
Action: Increase the value of the ENQUEUE_RESOURCES initialization parameter.
ORA-00053: maximum number of enqueues exceeded
Cause: Ran out of enqueue state objects.
Action: Increase the value of the ENQUEUES initialization parameter.
ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired
Cause: Interested resource is busy.
Action: Retry if necessary or increase timeout.
ORA-00055: maximum number of DML locks exceeded
Cause: Ran out of DML lock state objects.
Action: Increase the value of the DML_LOCKS initialization parameter and warm start.
ORA-00056: DDL lock on object 'string.string' is already held in an incompatible mode
Cause: An attempt was made to acquire a DDL lock that is already locked.
Action: This happens if you attempt to drop a table that has parse locks on it.
ORA-00057: maximum number of temporary table locks exceeded
Cause: The number of temporary tables equals or exceeds the number of temporary table locks. Temporary tables are often created by large sorts.
Action: Increase the value of the TEMPORARY_TABLE_LOCKS initialization parameter and warm start.
ORA-00058: DB_BLOCK_SIZE must be string to mount this database (not string)
Cause: DB_BLOCK_SIZE initialization parameter is wrong for the database being mounted. It does not match the value used to create the database.
Action: Fix the value of the DB_BLOCK_SIZE parameter or mount a database that matches the value.
ORA-00059: maximum number of DB_FILES exceeded
Cause: The value of the DB_FILES initialization parameter was exceeded.
Action: Increase the value of the DB_FILES parameter and warm start.
ORA-00060: deadlock detected while waiting for resource
Cause: Transactions deadlocked one another while waiting for resources.
Action: Look at the trace file to see the transactions and resources involved. Retry if necessary.
ORA-00061: another instance has a different DML_LOCKS setting
Cause: The shared instance being started is using DML locks, and the running instances are not, or vice-versa.
Action: Ensure that all instances' INIT.ORA files specify the DML_LOCKS parameter as 0 or all as non-zero.
ORA-00062: DML full-table lock cannot be acquired; DML_LOCKS is 0
Cause: The instance was started with DML_LOCKS = 0, and the statement being executed needs a full-table lock (S, X, or SSX).
Action: Restart the instance with DML_LOCKS not equal to zero, and reexecute the statement.
ORA-00063: maximum number of log files exceeded string
Cause: The number of log files specificied exceeded the maximum number of log files supported in this release.
Action: Re-create the control file with the highest number of log files no greater than the maximum supported in this release.
ORA-00064: object is too large to allocate on this O/S (string,string,string)
Cause: An initialization parameter was set to a value that required allocating more contiguous space than can be allocated on this operating system.
Action: Reduce the value of the initialization parameter.
ORA-00065: initialization of FIXED_DATE failed
Cause: The FIXED_DATE string was not in date format yyyy-mm-dd:hh24:mi:ss.
Action: Make sure the initialization parameter is in the correct date format.
ORA-00066: SID string contains an illegal character
Cause: The specified SID contains an illegal character which cannot occur in an SPFILE setting. Illegal characters include ,#"'=() and whitespace.

Cause: The database ID in the control file is not the same as the database ID in the control file used by the first instance to mount this database. Most likely one of the mounts used the wrong control file or there are two databases with the same name.
Action: Check that the control file is for the correct database and is not an old version.
ORA-00208: number of control file names exceeds limit of string
Cause: An attempt was made to use more control files than Oracle supports.
Action: Shut down Oracle. Reduce the number of control files specified in the CONTROL_FILES parameter in the initialization parameter file, and restart Oracle. Delete usused files.
ORA-00209: control file blocksize mismatch, check alert log for more info
Cause: The block size in the control file header does not match the size specified in the DB_BLOCK_SIZE parameter.
Action: Look at the alert log for more information.
ORA-00210: cannot open the specified control file
Cause: Cannot open the control file.
Action: Check to make sure the control file exists and is not locked by some other program.
ORA-00211: control file does not match previous control files
Cause: A control file was specified that belongs to another database.
Action: Find and install the correct control file.
ORA-00212: block size string below minimum required size of string bytes
Cause: The block size specified was too small. Space for the system overhead is required.
Action: Specify a larger block size and retry the operation.
ORA-00213: cannot reuse control file; old file size string, string required
Cause: To reuse a control file, it must be the same size as the one previously used.
Action: Either do not specify REUSE, or specify a matching combination of MAXDATAFILES, MAXLOGFILES, MAXLOGMEMBERS, MAXLOGHISTORY, and MAXINSTANCES clauses in the CREATE DATABASE or CREATE CONTROLFILE statement.
ORA-00214: control file 'string' version string inconsistent with file 'string' version string
Cause: An inconsistent set of control files, datafiles/logfiles, and redo files was used.
Action: Use a consistant set of control files, datafiles/logfiles, and redo log files. That is, all the files must be for the same database and from the same time period.
ORA-00215: must be at least one control file
Cause: No control file is specified or the control file specified does not exist.
Action: Specify at least one valid control file and retry the operation.
ORA-00216: control file could not be resized for migration from 8.0.2
Cause: The control file created by release 8.0.2 was missing some record types. These record types are automatically added by resizing the control file during mount. The resize has failed.
Action: Look in the alert log for the reason that the resize has failed. If indicated in the alert log, give the control file more space. Otherwise, use the CREATE CONTROLFILE script dumped to the trace file to create a new control file.
ORA-00217: control file could not be resized for new record types
Cause: The control file was missing some new record types supported by this release. These record types are automatically added by resizing the contol file during mount. The resize has failed.
Action: Look in the alert log for the reason that the resize has failed. If indicated in the alert log, give the control file more space. Otherwise, use the CREATE CONTROLFILE script dumped to the trace file to create a new control file.
ORA-00218: block size string of control file 'string' does not match DB_BLOCK_SIZE (string)
Cause: The block size as stored in the control file header is different from the value of the initialization parameter DB_BLOCK_SIZE. This might be due to an incorrect setting of DB_BLOCK_SIZE, or else might indicate that the control file has either been corrupted or belongs to a different database.
Action: Restore a good copy of the control file. If the control file is known to be clean set the DB_BLOCK_SIZE to match control file headers block size value.
ORA-00219: required control file size (string logical blocks) exceeds maximum allowable size (string logical blocks)
Cause: An invocation of CREATE DATABASE or CREATE CONTROLFILE was executed specifying a combination of parameters that would require the control file size in blocks to exceed the maximum allowable value.
Action: In the case of CREATE DATABASE or CREATE CONTROLFILE, use a different combination of MAXDATAFILES, MAXLOGFILES, MAXLOGMEMBERS, MAXLOGHISTORY, and MAXINSTANCES clauses.
ORA-00220: control file not mounted by first instance, check alert log for more info
Cause: The specified control file has a different mount ID than the other control files that are being mounted. This means that the first instance to mount the database did not use this control file.
Action: Find and install the correct control file.
ORA-00221: error on write to control file
Cause: An error occurred when writing to one or more of the control files.
Action: See accompanying messages.
ORA-00222: operation would reuse name of a currently mounted control file
Cause: The filename supplied as a parameter to the ALTER DATABASE BACKUP CONTROLFILE command or to cfileSetSnapshotName matches the name of the specified currently mounted control file.
Action: Retry the operation with a different filename.
ORA-00223: convert file is invalid or incorrect version
Cause: An Oracle7 to Oracle8 convert file contains invalid data or was created with an different version of the migration utility. This error can also be caused by incorrect ORACLE_HOME environment variable when ALTER DATABASE CONVERT command is issued.
Action: Use a correct version of the convert file or regenerate it with the migration utility. Make sure that the migration utility is the same version as the Oracle8 RDBMS executable and that the ORACLE_HOME environment variable is properly set.
ORA-00224: control file resize attempted with illegal record type (string)
Cause: An attempt was made to expand or shrink the control file by calling cfileResizeSection using an invalid value for the RECORD_TYPE parameter.
Action: Use a value for the RECORD_TYPE parameter that specifies a valid record type other than type 0 (valid range is 1-16).
ORA-00225: expected size string of control file differs from actual size string
Cause: The expected size of the control file as stored in its header was different than the actual operating system file size. This usually indicates that the control file was corrupted.
Action: Restore a good copy of the control file.
ORA-00226: operation disallowed while alternate control file open
Cause: The attempted operation could not be executed at this time because this process had an alternate control file open for fixed table access.
Action: Retry the operation after calling cfileUseCurrent.
ORA-00227: corrupt block detected in control file: (block string, # blocks string)
Cause: A block header corruption or checksum error was detected on reading the control file.
Action: Use the CREATE CONTROLFILE or RECOVER DATABASE USING BACKUP CONTROLFILE command.
ORA-00228: length of alternate control file name exceeds maximum of string
Cause: The specified filename, which was supplied as a parameter to cfileSetSnapshotName or cfileUseCopy, exceeds the maximum filename length for this operating system.
Action: Retry the operation with a shorter filename.
ORA-00229: operation disallowed: already hold snapshot control file enqueue
Cause: The attempted operation cannot be executed at this time because this process currently holds the snapshot control file enqueue.
Action: Retry the operation after calling cfileUseCurrent to release the snapshot control file enqueue.
ORA-00230: operation disallowed: snapshot control file enqueue unavailable
Cause: The attempted operation cannot be executed at this time because another process currently holds the snapshot control file enqueue.
Action: Retry the operation after the concurrent operation that is holding the snapshot control file enqueue terminates.
ORA-00231: snapshot control file has not been named
Cause: During an invocation of cfileMakeAndUseSnapshot or cfileUseSnapshot it was detected that no filename for the snapshot control file had previously been specified.
Action: Specify a name for the snapshot control file by calling cfileSetSnapshotName.
ORA-00232: snapshot control file is nonexistent, corrupt, or unreadable
Cause: The snapshot control file was found to be nonexistent, corrupt, or unreadable during an invocation of cfileUseSnapshot.
Action: Call cfileMakeAndUseSnapshot again (or for the first time).
ORA-00233: copy control file is corrupt or unreadable
Cause: The specified copy control file was found to be corrupt or unreadable during an invocation of cfileUseCopy.
Action: Before retrying cfileUseCopy, use the ALTER DATABASE BACKUP CONTROLFILE command and specify the same filename that was specified for cfileUseCopy.
ORA-00234: error in identifying or opening snapshot or copy control file
Cause: A snapshot or copy control file of the specified name could not be found or opened during an invocation of cfileUseSnapshot, cfileMakeAndUseSnapshot, or cfileUseCopy.
Action: Re-create the snapshot or copy control file using cfileMakeAndUseSnapshot or ALTER DATABASE BACKUP CONTROLFILE, respectively.
ORA-00235: control file read without a lock inconsistent due to concurrent update
Cause: Concurrent update activity on a control file caused a process to read inconsistent information from the control file without a lock.
Action: Retry the operation.
ORA-00236: snapshot operation disallowed: mounted control file is a backup
Cause: Attempting to invoke cfileSetSnapshotName, cfileMakeAndUseSnapshot, or cfileUseSnapshot when the currently mounted control file is a backup control file.
Action: Mount a current control file and retry the operation.
ORA-00237: snapshot operation disallowed: control file newly created
Cause: An attempt to invoke cfileMakeAndUseSnapshot with a currently mounted control file that was newly created with CREATE CONTROLFILE was made.
Action: Mount a current control file and retry the operation.
ORA-00238: operation would reuse a filename that is part of the database
Cause: The filename supplied as a parameter to the ALTER DATABASE BACKUP CONTROLFILE command or to cfileSetSnapshotName matches the name of a file that is currently part of the database.
Action: Retry the operation with a different filename.
ORA-00239: timeout waiting for control file enqueue: held by 'string' for more than string seconds
Cause: The specified process waited the maximum allowed time for the control file enqueue.
Action: Restart the blocking instance indicated in the incident trace file or reboot the blocking node.
ORA-00240: control file enqueue held for more than string seconds
Cause: The current process did not release the control file enqueue within the maximum allowed time.
Action: Reissue any commands that failed and contact Oracle Support Services with the incident information.
ORA-00250: archiver not started
Cause: An attempt was made to stop automatic archiving, but the archiver process was not running.
Action: No action required.
ORA-00251: LOG_ARCHIVE_DUPLEX_DEST cannot be the same destination as string string
Cause: The destination specified by the LOG_ARCHIVE_DUPLEX_DEST parameter is the same as the destination specified by an ALTER SYSTEM ARCHIVE LOG START TO command.
Action: Specify a different destination for parameter LOG_ARCHIVE_DUPLEX_DEST, or specify a different destination with the ALTER SYSTEM command.
ORA-00252: log string of thread string is empty, cannot archive
Cause: A log must be used for redo generation before it can be archived. The specified redo log was not been used since it was introduced to the database. However it is possible that instance death during a log switch left the log empty.
Action: Empty logs do not need to be archived. Do not attempt to archive the redo log file.
ORA-00253: character limit string exceeded by archive destination string string
Cause: The destination specified by an ALTER SYSTEM ARCHIVE LOG START TO command was too long.
Action: Retry the ALTER SYSTEM command using a string shorter than the limit specified in the error message.
ORA-00254: error in archive control string 'string'
Cause: The specified archive log location is invalid in the archive command or the LOG_ARCHIVE_DEST initialization parameter.
Action: Check the archive string used to make sure it refers to a valid online device.
ORA-00255: error archiving log string of thread string, sequence # string
Cause: An error occurred during archiving.
Action: Check the accompanying message stack for more detailed information. If the online log is corrupted, then the log can be cleared using the UNARCHIVED option. This will make any existing backups useless for recovery to any time after the log was created, but will allow the database to generate redo.
ORA-00256: cannot translate archive destination string string
Cause: The destination specified by an ALTER SYSTEM ARCHIVE LOG START TO command could not be translated.
Action: Check the accompanying message stack for more detailed information. Then, retry the ALTER SYSTEM command using a different string.
ORA-00257: archiver error. Connect internal only, until freed.
Cause: The archiver process received an error while trying to archive a redo log. If the problem is not resolved soon, the database will stop executing transactions. The most likely cause of this message is the destination device is out of space to store the redo log file.
Action: Check archiver trace file for a detailed description of the problem. Also verify that the device specified in the initialization parameter ARCHIVE_LOG_DEST is set up properly for archiving.
ORA-00258: manual archiving in NOARCHIVELOG mode must identify log
Cause: The database is in NOARCHIVELOG mode and a command to manually archive a log did not specify the log explicitly by sequence number, group number or filename.
Action: Specify log by filename, by group number or by thread and sequence number.
ORA-00259: log string of open instance string (thread string) is the current log, cannot archive
Cause: An attempt was made to archive the current log of an open thread. This is not allowed because the redo log file may still be in use for the generation of redo entries.
Action: Force a log switch in the instance where the thread is open. If no instances are open, open the database so that instance recovery can recover the thread.
ORA-00260: cannot find online log sequence string for thread string
Cause: The log sequence number supplied to the archival command does not match any of the online logs for the thread. The log might have been reused for another sequence number, it might have been dropped, the sequence number might be greater than the current log sequence number, or the thread might not have any logs.
Action: Check the ARCHIVE statement, then specify a valid log sequence number. Specify a valid log sequence number.
ORA-00261: log string of thread string is being archived or modified
Cause: The log is either being archived by another process or an administrative command is modifying the log. Operations that modify the log include clearing, adding a member, dropping a member, renaming a member, and dropping the log.
Action: Wait for the current operation to complete and try again.
ORA-00262: current log string of closed thread string cannot switch
Cause: The log cannot be cleared or manually archived because it is the current log of a closed thread, and it is not possible to switch logs so another log is current. All other logs for the thread need to be archived, or cleared, and cannot be reused.
Action: Archive another log in the same thread first, or complete the clearing. See attached errors for the reason the switch cannot be completed.
ORA-00263: there are no logs that need archiving for thread string
Cause: An attempt was made to manually archive the unarchived logs in this thread but no logs needed archiving.
Action: No action required.
ORA-00264: no recovery required
Cause: An attempt was made to perform media recovery on files that do not // need any type of recovery.
Action: Do not attempt to perform media recovery on the selected files. Check to see that the filenames were entered properly. If not, retry the command with the proper filenames.
ORA-00265: instance recovery required, cannot set ARCHIVELOG mode
Cause: The database either crashed or was shutdown with the ABORT option. Media recovery cannot be enabled because the online logs may not be sufficient to recover the current datafiles.
Action: Open the database and then enter the SHUTDOWN command with the NORMAL or IMMEDIATE option.
ORA-00266: name of archived log file needed
Cause: During media recovery, the name of an archived redo log file was requested, but no name was entered.
Action: Mount the correct redo log file and enter its name when it is requested.
ORA-00267: name of archived log file not needed
Cause: During media recovery, the name of an archived redo log file was entered, but no name was requested.
Action: Continue media recovery, but do not enter a new log name.
ORA-00268: specified log file does not exist 'string'
Cause: The given redo log file does not exist.
Action: Check the spelling and capitalization of the filename and retry the command.
ORA-00269: specified log file is part of thread string not string
Cause: The given redo log file is not part of the given thread
Action: Check that the thread of the redo log file matches the thread on the command line. If not, use a redo log file from the appropriate thread. Retry the command after correcting the error.
ORA-00270: error creating archive log string
Cause: An error was encountered when either creating or opening the destination file for archiving.
Action: Check that the archive destination is valid and that there is sufficient space on the destination device.
ORA-00271: there are no logs that need archiving
Cause: An attempt was made to archive the unarchived redo log files manually, but there are no files that need to be archived.
Action: No action required.
ORA-00272: error writing archive log string
Cause: An I/O error occurred while archiving a redo log file.
Action: Check that the output device is still available and correct any device errors that may have occurred. Also, make certain that sufficient space for archiving is available on the output device.
ORA-00273: media recovery of direct load data that was not logged
Cause: A media recovery session encountered a table that was loaded by the direct loader without logging any redo information. Some or all of the blocks in this table are now marked as corrupt.
Action: The table must be dropped or truncated so that the corrupted blocks can be reused. If a more recent backup of the file is available, try to recover this file to eliminate this error.
ORA-00274: illegal recovery option string
Cause: An illegal option was specified for a recovery command.
Action: Correct the syntax and retry the command.
ORA-00275: media recovery has already been started
Cause: An attempt was made to start a second media recovery operation in the same session.
Action: Complete or cancel the first media recovery session or start another session to perform media recovery.
ORA-00276: CHANGE keyword specified but no change number given
Cause: The CHANGE keyword was specified on the command line, but no change number was given.
Action: Retry the command using a valid change number after the CHANGE keyword.
ORA-00277: illegal option to the UNTIL recovery flag string
Cause: Only CANCEL, CHANGE, CONSISTENT and TIME can be used with the UNTIL keyword.
Action: Correct the syntax.
ORA-00278: log file 'string' no longer needed for this recovery
Cause: The specified redo log file is no longer needed for the current recovery.
Action: No action required. The archived redo log file may be removed from its current location to conserve disk space, if needed. However, the redo log file may still be required for another recovery session in the future.
ORA-00279: change string generated at string needed for thread string
Cause: The requested log is required to proceed with recovery.
Action: Please supply the requested log with "ALTER DATABASE RECOVER LOGFILE <file_name>" or cancel recovery with "ALTER DATABASE RECOVER CANCEL".
ORA-00280: change string for thread string is in sequence #string
Cause: This message helps to locate the redo log file with the specified change number requested by other messages.
Action: Use the information provided in this message to specify the required archived redo log files for other errors.
ORA-00281: media recovery may not be performed using dispatcher
Cause: An attempt was made to use a dispatcher process for media recovery. Memory requirements disallow this recovery method.
Action: Connect to the instance via a dedicated server process to perform media recovery.
ORA-00282: UPI string call not supported, use ALTER DATABASE RECOVER
Cause: The given UPI call is no longer supported.
Action: Use the ALTER DATABASE RECOVER command for all recovery actions.
ORA-00283: recovery session canceled due to errors
Cause: An error during recovery was determined to be fatal enough to end the current recovery session.
Action: More specific messages will accompany this message. Refer to the other messages for the appropriate action.
ORA-00284: recovery session still in progress
Cause: An error during recovery was determined to be minor enough to allow the current recovery session to continue.
Action: More specific messages will accompany this message. Refer to the other messages for the appropriate action.
ORA-00285: TIME not given as a string constant
Cause: UNTIL TIME was not followed by a string constant for the time.
Action: Enter the time enclosed in single quotation marks.
ORA-00286: no members available, or no member contains valid data
Cause: None of the members of a redo log file group are available, or the available members do not contain complete data.
Action: If a member is temporarily offline, attempt to make it available. Make sure that the correct filenames are being used, especially if the redo log file is being accessed from a remote location.
ORA-00287: specified change number string not found in thread string
Cause: The given change number does not appear in any of the online redo logs for the given thread.
Action: Check the statement to make certain a valid change number is given. Perhaps try to use the NEXT option for archiving logs.
ORA-00288: to continue recovery type ALTER DATABASE RECOVER CONTINUE
Cause: During media recovery, a new log is not required but the continuation command is necessary to do a checkpoint and report errors.
Action: Type ALTER DATABASE RECOVER CONTINUE and recovery will resume.
ORA-00289: suggestion : string
Cause: This message reports the next redo log filename that is needed, according to the initialization parameters LOG_ARCHIVE_DEST and LOG_ARCHIVE_FORMAT. This message assumes that LOG_ARCHIVE_DEST and LOG_ARCHIVE_FORMAT are the same now as when the required redo log file was archived.
Action: Consider using this filename for the next log needed for recovery.
ORA-00290: operating system archival error occurred. See error below
Cause: While attempting to archive to a redo log file, the server encountered an unexpected operating system error.
Action: Correct the operating system error given in the messages and retry the operation. See also your operating system-specific Oracle documentation.
ORA-00291: numeric value required for PARALLEL option
Cause: A recovery command was specified incorrectly. The PARALLEL option must be followed by a numeric argument that specifies the degree of parallelism.
Action: Re-enter the command with a numeric argument specifying the degree of parallelism desired.
ORA-00292: parallel recovery feature not installed
Cause: A parallel recovery was requested when the parallel recovery option is not installed.
Action: Delete the PARALLEL clause from the RECOVER command. Also, delete the RECOVERY_PARALLELISM parameter in the initialization file.
ORA-00293: control file out of sync with redo log
Cause: The redo log file and control file are out of sync because a non-current controle file was specified when the instance was started.
Action: Retry the RECOVER command using the current control file, or retry the RECOVER command using the USING BACKUP CONTROLFILE clause.
ORA-00294: invalid archivelog format specifier 'string'
Cause: An invalid format specifier was found in the LOG_ARCHIVE_FORMAT initialization parameter. The only characters permitted following the % symbol are s, S, t, and T.
Action: Correct the initialization file and re-start the instance.
ORA-00295: datafile/tempfile number string is invalid, must be between 1 and string
Cause: An invalid file number was specified.
Action: Specify a valid datafile or tempfile number and retry the operation.
ORA-00296: maximum number of files (string) exceeded for RECOVER DATAFILE LIST
Cause: The RECOVER DATAFILE LIST command specified more datafiles than are allowed by the DB_FILES initialization parameter. This error occurs when doing recovery with Recovery Manager, and the instance has been started with a DB_FILES parameter specifying fewer datafiles than recovery manager needs to recover to satisfy the user's RECOVER command.
Action: Re-start the instance with a higher value for DB_FILES.
ORA-00297: must specify RECOVER DATAFILE LIST before RECOVER DATAFILE START
Cause: The RECOVER DATAFILE START command was issued, but no RECOVER DATAFILE LIST commands had been issued. This only happens when doing recovery with Recovery Manager, and is an internal error in Recovery Manager, because Recovery Manager should always issue RECOVER DATAFILE LIST before RECOVER DATAFILE START.
Action: Contact customer support
ORA-00298: Missing or invalid attribute value
Cause: A non-zero integer value is required when the following keyword attributes are specified: TIMEOUT, EXPIRE, DELAY, NEXT
Action: Correct the syntax and retry the command.
ORA-00299: must use file-level media recovery on data file string
Cause: The control file does not contain an entry for this file, so block media recovery cannot be done.
Action: Restore the data file and perform file-level media recovery.
ORA-00300: illegal redo log block size string specified - exceeds limit of string
Cause: The specified block size of the redo log is greater than the maximum block size for the operating system.
Action: Create the redo log on a device with a smaller block size
ORA-00301: error in adding log file 'string' - file cannot be created
Cause: The creation of the redo log file failed
Action: Check: 1) there is enough storage space on the device 2) the name of the file is valid 3) the device is online 4) an IO error occurred Also, it is possible REUSE was specified on the command line and a file of the incorrect size exists. Either do not specify REUSE or use a file of the correct size.
ORA-00302: limit of string logs exceeded
Cause: The maximum number of redo log files has been exceeded.
Action: Use the CREATE CONTROLFILE command with a larger value for MAXLOGFILES if the compatibility is lower than 10.2.0. Otherwise, allocate more storage space for the control file.
ORA-00303: cannot process Parallel Redo
Cause: A redo log containing Parallel Redo has been detected. The current Oracle release cannot process this format of redo.
Action: Use a later release that supports Parallel Redo. to process this log.
ORA-00304: requested INSTANCE_NUMBER is busy
Cause: An instance tried to start by using a value of the initialization parameter INSTANCE_NUMBER that is already in use.
Action: Either a) specify another INSTANCE_NUMBER, b) shut down the running instance with this number c) wait for instance recovery to complete on the instance with this number.
ORA-00305: log string of thread string inconsistent; belongs to another database
Cause: The database ID in the redo log file does not match the database ID in the control file. This redo log file is not from the current database.
Action: Specify the correct redo log file, then retry the operation.
ORA-00306: limit of string instances in this database
Cause: Starting this instance would exceed the maximum number of instances allowed for this database. This message occurs only with STARTUP shared and multiple instances.
Action: You cannot start more than the lower of a) port-specific limit as to the number of instances b) the number of instances specified at create-database time
ORA-00307: requested INSTANCE_NUMBER out of range, maximum is string
Cause: The initialization parameter INSTANCE_NUMBER specified a number that was out of range.
Action: Change INSTANCE_NUMBER to a valid range and restart the instance. The minimum value is one and the maximum value is the lower of the operating system-specific maximum or the MAXINSTANCES option specified in the CREATE DATABASE statement. See also your operating system-specific Oracle documentation.
ORA-00308: cannot open archived log 'string'
Cause: The system cannot access a required archived redo log file.
Action: Check that the off line log exists, the storage device is online, and the archived file is in the correct location. Then attempt to continue recovery or restart the recovery session.
ORA-00309: log belongs to wrong database
Cause: The system cannot access the archived redo log because it belongs to another database.
Action: Specify the correct redo log file, then retry the operation.
ORA-00310: archived log contains sequence string; sequence string required
Cause: The archived log is out of sequence, probably because it is corrupted or the wrong redo log filename was specified
Action: Specify the correct redo log file; then retry the operation.
ORA-00311: cannot read header from archived log
Cause: An I/O error occurred when attempting to read the log file header from the specified archived redo log file.

Cause: Attempt to open thread failed because it is necessary to switch redo generation to another online log, but all the other logs need to be archived before they can be used.
Action: Archive the logs for the thread then retry open.
ORA-00324: log file 'string' translated name 'string' too long, string characters exceeds string limit
Cause: the translated name for a log file is too long.
Action: Choose a untranslated name that yields a shorter translated name.
ORA-00325: archived log for thread string, wrong thread # string in header
Cause: The archived log is corrupted or for another thread. Can not use the log for applying redo.
Action: Find correct archived log.
ORA-00326: log begins at change string, need earlier change string
Cause: The archived log supplied for recovery was generated after the log that is needed. Can not yet use the log for applying redo.
Action: Find correct archived log.
ORA-00327: log string of thread string, physical size string less than needed string
Cause: A log file has shrunk in size. This is likely to have been caused by operator or operating system error.
Action: Restore the log file from backup. If backup is not available, drop this log and re-create. If the database was shut down cleanly, no further action should be required; otherwise incomplete recovery may be required.
ORA-00328: archived log ends at change string, need later change string
Cause: The archived log supplied for recovery was generated before the log that is needed. Can not use the log for applying redo.
Action: Find correct archived log.
ORA-00329: archived log begins at change string, need change string
Cause: The archived log is not the correct log. An earlier log is needed.

Cause: The log was written by incompatible version of Oracle.
Action: Recover the database with the compatible software, shut it down cleanly, then restart with current software.
ORA-00332: archived log is too small - may be incompletely archived
Cause: The log is smaller than the space allocated in it. May be the result of a shutdown abort while it was being written by the archiver.
Action: Get a complete version of this log and use it for recovery. There should either be an online version of it or a copy that was successfully archived.
ORA-00333: redo log read error block string count string
Cause: An IO error occurred while reading the log described in the accompanying error.
Action: Restore accessibility to file, or get another copy of the file.
ORA-00334: archived log: 'string'
Cause: Reporting filename for details of another error
Action: See associated error messages
ORA-00335: online log string: No log with this number, log does not exist
Cause: Reporting filename for details of another error
Action: See associated error messages
ORA-00336: log file size string blocks is less than minimum string blocks
Cause: The log file size as specified in create database is too small.
Action: Increase the log file size.
ORA-00337: log file 'string' does not exist and no size specified
Cause: An attempt to add a log found neither an existing file nor a size for creating the file.
Action: Specify a size for the log file.
ORA-00338: log string of thread string is more recent than control file
Cause: The control file change sequence number in the log file is greater than the number in the control file. This implies that the wrong control file is being used. Note that repeatedly causing this error can make it stop happening without correcting the real problem. Every attempt to open the database will advance the control file change sequence number until it is great enough.
Action: Use the current control file or do backup control file recovery to make the control file current. Be sure to follow all restrictions on doing a backup control file recovery.
ORA-00339: archived log does not contain any redo
Cause: The archived log is not the correct log. It is a copy of a log file that has never been used for redo generation, or was an online log being prepared to be the current log.
Action: Restore the correct log file.
ORA-00340: IO error processing online log string of thread string
Cause: An IO error occurred on the named online log.
Action: Restore accessibility to file, or restore file from backup.
ORA-00341: log string of thread string, wrong log # string in header
Cause: The internal information in an online log file does not match the control file.
Action: Restore correct file or reset logs.
ORA-00342: archived log does not have expected resetlogs SCN string
Cause: Recovery was given a log that does not belong to current incarnation or one of the parent incarnation. There should be another log that contains the correct redo.
Action: Supply the correct log file.
ORA-00344: unable to re-create online log 'string'
Cause: An I/O failure occurred when attempting to re-create an online as part of either ALTER DATABASE OPEN RESETLOGS or ALTER DATABASE CLEAR LOGFILE command.
Action: Correct the file/device as indicated by accompanying errors.
ORA-00345: redo log write error block string count string
Cause: An IO error has occurred while writing the log
Action: Correct the cause of the error, and then restart the system. If the log is lost, apply media/incomplete recovery.
ORA-00346: log member marked as STALE and closed
Cause: A log file member was no longer complete.
Action: Correct the underlying problem by referring to the other error messages found with this one.
ORA-00347: log string of thread string, expected block size string doesn't match string
Cause: On header read the blocksize indicated in the control file did not match the blocksize contained in the log file.
Action: Restore correct file or reset logs.
ORA-00348: single-process redo failure. Must abort instance
Cause: A failure occurred during a critical portion of the log code during single process operation. This error does not occur during normal multi-process operation.
Action: Shutdown abort and warmstart the database.
ORA-00349: failure obtaining block size for 'string'
Cause: The operating system was unable to determine the blocksize for the given filename.
Action: Consult the accompanying error message, and correct the device or specify another filename.
ORA-00350: log string of instance string (thread string) needs to be archived
Cause: The command cannot be done because the log has not been archived, and media recovery has been enabled.
Action: Archive the log or disable media recovery. If the command supports an UNARCHIVED option then it can be used. However this may result in making backups unuseable, and forcing the drop of some offline files.
ORA-00351: recover-to time invalid
Cause: The time specified in a recover-until statement must be after January 1st 1988.
Action: Specify a time after January 1st 1988.
ORA-00352: all logs for thread string need to be archived - cannot enable
Cause: Attempting to enable a thread with all logs needing to be archived, and media recovery has been enabled. There is no log that can be made the new current log for the thread.
Action: Archive a log for the thread or disable media recovery.
ORA-00353: log corruption near block string change string time string
Cause: Some type of redo log corruption has been discovered. This error describes the location of the corruption. Accompanying errors describe the type of corruption.
Action: Do recovery with a good version of the log or do incomplete recovery up to the indicated change or time.
ORA-00354: corrupt redo log block header
Cause: The block header on the redo block indicated by the accompanying error, is not reasonable.
Action: Do recovery with a good version of the log or do time based recovery up to the indicated time. If this happens when archiving, archiving of the problem log can be skipped by clearing the log with the UNARCHIVED option. This must be followed by a backup of every datafile to insure recoverability of the database.
ORA-00355: change numbers out of order
Cause: A change number found in the redo log is lower than a previously encountered change number. The log is corrupted in some way. The corruption may be at the earlier change or at this one.
Action: Do recovery with a good version of the log or do time based recovery up to the indicated time.
ORA-00356: inconsistent lengths in change description
Cause: A change record in the redo log contains lengths that do not add up to a consistent value. The log is corrupted in some way.
Action: Do recovery with a good version of the log or do time based recovery up to the indicated time.
ORA-00357: too many members specified for log file, the maximum is string
Cause: An add logfile or add logfile member command would result in a log with too many members. The number of members is set when the database is created.
Action: Use fewer log file members.
ORA-00358: Too many file members specified, the maximum is string
Cause: A create or alter statement specified too many members in a parenthesised file list.
Action: Specify a number of file members that is within the port-defined limit.
ORA-00359: logfile group string does not exist
Cause: An add logfile member or drop logfile request specified a logfile group number that does not exist.
Action: Check the configuration of the log files and reissue the command.
ORA-00360: not a logfile member: string
Cause: A filename was given to drop logfile member that is not a part of the database, or which is a data file.
Action: Supply a valid logfile member name.
ORA-00361: cannot remove last log member string for group string
Cause: An attempt has been made to remove the last member of a log file group.
Action: If desired, delete the entire log, by using DROP LOGFILE.
ORA-00362: member is required to form a valid logfile in group string
Cause: A request to drop a logfile member was denied because it would remove data required to form a complete logfile.
Action: If desired, delete the entire log (after archiving if required), by using DROP LOGFILE;
ORA-00363: log is not the archived version
Cause: d by failing to list the current log of an enabled thread in a CREATE CONTROLFILE command.
Action: Find the archived version of the log and supply its name. If this is media recovery immediately following a CREATE CONTROLFILE, be sure the current log for this thread was included.
ORA-00364: cannot write header to new log member
Cause: An i/o error occurred when attempting to write the header to a log member that is being added to an existing group.
Action: See accompanying errors. Fix problem or use another file.
ORA-00365: the specified log is not the correct next log
Cause: The specified log failed to pass checks to ensure it corresponds to the log that was just applied. This is probably the result of using a log that was generated against a cold backup image of the database.
Action: Find the log that was generated by this copy of the database and give that filename to recovery.
ORA-00366: log string of thread string, checksum error in the file header
Cause: The file header for the redo log contains a checksum that does not match the value calculated from the file header as read from disk. This means the file header is corrupted
Action: Find and install correct version of log or reset logs.
ORA-00367: checksum error in log file header
Cause: The file header for the redo log contains a checksum that does not match the value calculated from the file header as read from disk. This means the file header is corrupted
Action: Find the correct file and try again.
ORA-00368: checksum error in redo log block
Cause: The redo block indicated by the accompanying error, is not vaild. It has a checksum that does not match the block contents.
Action: Restore correct file or reset logs.
ORA-00369: Current log of thread string not useable and other log being cleared
Cause: Attempt to open thread failed because it is necessary to switch redo generation to another online log, but all the other logs are being cleared or need to be archived before they can be used.
Action: If the ALTER DATABASE CLEAR LOGFILE command is still active then wait for it to complete. Otherwise reissue the CLEAR command. If there are other online logs for the thread, that are not being cleared, then archive the logs.
ORA-00370: potential deadlock during kcbchange operation
Cause: Error code used internally by software. Should never be reported
Action: Treat as internal error. See error 600.
ORA-00371: not enough shared pool memory, should be atleast string bytes
Cause: Init.ora parameter shared_pool_size is too small
Action: Increase the parameter value
ORA-00372: file string cannot be modified at this time
Cause: attempting to modify the contents of a file that cannot be modified. The file is most likely part of a read only tablespace but may be in the process of going offline, or the database may be in the process of closing.
Action: check the status of the file and its tablespace
ORA-00373: online log version string incompatible with ORACLE version string
Cause: The online log was written by incompatible version of Oracle. Can occur when the log file was created by either a new or older version of Oracle.
Action: Recover the database with the compatible software, shut it down cleanly, then restart with current software.
ORA-00374: parameter db_block_size = string invalid ; must be a multiple of string in the range [string..string]
Cause: invalid value for db_block_size parameter
Action: adjust parameter and restart
ORA-00376: file string cannot be read at this time
Cause: attempting to read from a file that is not readable. Most likely the file is offline.
Action: Check the state of the file. Bring it online
ORA-00377: Frequent backups of file string causing write operation to stall
Cause: Backups are occurring too frequently on this file. Each time a new backup is started for a file, any writes which have been previously issued (but not completed) have to be re-issued. If hot backups are started very, very frequently, it is possible that some writes will be re-issued repeatedly and never complete.
Action: Increase the interval between begin hot-backup commands for this file.
ORA-00378: buffer pools cannot be created as specified
Cause: Either the number of buffers or the number of lru latches is too small to satisfy the specified buffer pool configuration.
Action: Either increase the number of buffers and/or number of lru latches or configure smaller buffer pools.
ORA-00379: no free buffers available in buffer pool string for block size stringK
Cause: All buffers in the specified buffer pool for the specified block size are in use and no free buffers are available.
Action: Increase the number of buffers in the specified pool for the specified block size
ORA-00380: cannot specify db_stringk_cache_size since stringK is the standard block size
Cause: User specified the parameter db_nk_cache_size (where n is one of 2,4,8,16,32), while the standard block size for this database is equal to n Kbytes. This is illegal.
Action: Specify the standard block size cache using db_cache_size (DEFAULT pool) (and db_recycle_cache_size, db_keep_cache_size if additional buffer pools are required). Do NOT use the corresponding db_nk_cache_size parameter for the standard block size.
ORA-00381: cannot use both new and old parameters for buffer cache size specification
Cause: User specified one or more of { db_cache_size , db_recycle_cache_size, db_keep_cache_size, db_nk_cache_size (where n is one of 2,4,8,16,32), db_cache_advice } AND one or more of { db_block_buffers, buffer_pool_keep , buffer_pool_recycle }. This is illegal.
Action: Use EITHER the old (pre-Oracle_8.2) parameters OR the new ones. Don't specify both. If old size parameters are specified in the parameter file, you may want to replace them with new parameters since the new parameters can be modified dynamically and allow you to configure additional caches for additional block sizes. Cache advisory can only be enabled with the new cache parameters.
ORA-00382: string not a valid block size, valid range [string..string]
Cause: User specified a value for db_nk_cache_size where n is one of {2, 4, 8, 16, 32}, but nk is not a valid block size for this platform.
Action: Remove corresponding parameter from the "init.ora" file and restart the instance.
ORA-00383: DEFAULT cache for blocksize string cannot be reduced to zero
Cause: User attempted to reduce db_cache_size to zero, or attempted to to reduce db_<n>K_cache_size to zero while there were still online tablespaces with blocksize <n>K. Note that since the SYSTEM tablespace cannot be taken offline, it is always illegal to set db_cache_size to zero.
Action: Offline any tablespaces with the corresponding blocksize and then perform the operation again.
ORA-00384: Insufficient memory to grow cache
Cause: The system could not allocate sufficient memory to grow the cache to the specified size.
Action: Attempt a smaller increase in the value of the parameter.
ORA-00385: cannot enable Very Large Memory with new buffer cache parameters
Cause: User specified one or more of { db_cache_size , db_recycle_cache_size, db_keep_cache_size, db_nk_cache_size (where n is one of 2,4,8,16,32) } AND use_indirect_data_buffers is set to TRUE. This is illegal.
Action: Very Large Memory can only be enabled with the old (pre-Oracle_8.2) parameters.
ORA-00386: use_indirect_data_buffers not supported
Cause: The system could not allocate sufficient memory to grow the cache to the specified size.
Action: Attempt a smaller increase in the value of the parameter.
ORA-00390: log string of thread string is being cleared, cannot become current log
Cause: An attempt to switch to a new online log for the redo thread failed because no reusable log could be found. This log is being cleared and will be useable when the clearing completes. The command that began the clearing may have terminated without completing the clearing.
Action: If the clear command is still executing then wait for its completion. If it terminated then reissue the clear command, or drop the log.
ORA-00391: All threads must switch to new log format at the same time
Cause: An attempt to switch the current log of a single thread is not allowed because the compatiblity requirements force a new log format version number. When changing log formats, all threads must switch to the new format at the same time.
Action: Open the database to cause the coordinated log switch. If that is not possible then return to the same software version and compatibility setting last used to open the database.
ORA-00392: log string of thread string is being cleared, operation not allowed
Cause: An operation encountered this online log in the middle of being cleared. The command that began the clearing may have terminated without completing the clearing.
Action: If the clear command is still executing then wait for its completion. If it terminated then reissue the clear command, or drop the log.
ORA-00393: log string of thread string is needed for recovery of offline datafiles
Cause: Log cannot be cleared because the redo in it is needed to recover offline datafiles. It has not been archived so there is no other copy available. If the log is cleared the tablespaces containing the files will have to be dropped.
Action: Archive the log then repeat the clear command. If archiving is not possible, and dropping the tablespaces is acceptible, then add the clause UNRECOVERABLE DATAFILE at the end of the clear command.
ORA-00394: online log reused while attempting to archive it
Cause: It has been detected that an online log that is being archived has been reused
Action: Cannot archive the logfile anymore since it has been overwritten
ORA-00395: online logs for the clone database must be renamed
Cause: A clone database open forces logfile renaming to avoid overwriting the primary logfiles
Action: Rename the logfiles manually or using the log_file_name_convert initialization parameter
ORA-00396: error string required fallback to single-pass recovery
Cause: The indicated error caused two-pass instance or crash recovery to fail. Recovery was retried with an alternate (slower) method to avoid the error.
Action: Correct the cause of the indicated error (also recorded) so that future instance or crash recovery can succeed with the two-pass algorithm. This usually requires making more main memory available to the recovery process.
ORA-00397: instance recovery process terminated with error
Cause: The foreground process doing instance recovery died.
Action: Check the foreground trace file for the cause of recovery failure.
ORA-00398: abort thread recovery due to reconfiguration
Cause: Global enqueue service reconfiguration occurred during instance/crash recovery.
Action: This is used internally, no action is required.
ORA-00399: corrupt change description in redo log
Cause: A change vector in the redo log failed validation checks.
Action: Do recovery with a good version of the log or do time based recovery up to the indicated time.
ORA-00400: invalid release value string for parameter string
Cause: The release level given for the specified init parameter is invalid.
Action: Correct the parameter value in the parameter file and retry.
ORA-00401: the value for parameter string is not supported by this release
Cause: The value specified cannot be supported by this release of the software.
Action: Choose an appropriate value, or remove the parameter value to use the default value.
ORA-00402: database changes by release string cannot be used by release string
Cause: Changes have been made to the database that require a newer software release or that violate the compatibility parameters.
Action: Use a version of the software that can understand the changes or relax the compatibility requirements in the init file.
ORA-00403: string (string) is not the same as other instances (string)
Cause: Another instance has set the compatible or compatible no recovery parameters differently than this instance.
Action: Change the parameters of the current instance to match other instances already running.
ORA-00404: Convert file not found: 'string'
Cause: The file used for converting the database from V7 to V8 could not be found.
Action: Verify that the migration process has been started on this database and that the convert filename is accessable.
ORA-00405: compatibility type "string"
Cause: Reporting a type associated with another error.
Action: See accompanying error
ORA-00406: COMPATIBLE parameter needs to be string or greater
Cause: The COMPATIBLE initialization parameter is not high enough to allow the operation. Allowing the command would make the database incompatible with the release specified by the current COMPATIBLE parameter.
Action: Shutdown and startup with a higher compatibility setting.
ORA-00407: rolling upgrade from release string.string to string.string is not allowed
Cause: Another instance executing software at a different point release already has the database mounted.
Action: Shutdown all instances then startup with the new software.
ORA-00408: parameter string is set to TRUE
Cause: Reporting the parameter that resulted in the compatibility error.
Action: Shutdown and startup with a higher compatibility setting.
ORA-00409: COMPATIBLE needs to be string or higher to use AUTO SEGMENT SPACE MANAGEMENT
Cause: This is due to migrating from an older release of Oracle with tablespaces created using AUTO SEGMENT SPACE MANAGEMENT. To open the database, the COMPATIBLE parameter needs to be set to the specified value.
Action: Shutdown and startup with the specified compatibility setting.
