ORA-01002: fetch out of sequence
Cause: This error means that a fetch has been attempted from a cursor which is no longer valid. Note that a PL/SQL cursor loop implicitly does fetches, and thus may also cause this error. There are a number of possible causes for this error, including: 1) Fetching from a cursor after the last row has been retrieved and the ORA-1403 error returned. 2) If the cursor has been opened with the FOR UPDATE clause, fetching after a COMMIT has been issued will return the error. 3) Rebinding any placeholders in the SQL statement, then issuing a fetch before reexecuting the statement.
Action: 1) Do not issue a fetch statement after the last row has been retrieved - there are no more rows to fetch. 2) Do not issue a COMMIT inside a fetch loop for a cursor that has been opened FOR UPDATE. 3) Reexecute the statement after rebinding, then attempt to fetch again.

Cause: One of the following: 1) You attempted an invalid OCI operation. 2) You are using an Oracle client application linked with version 7.1 (or higher) libraries, the environment variable ORA_ENCRYPT_LOGIN is set to TRUE, and you attempted to connect to a version 7.0 (or lower) Oracle Server. 3) You are connected to a version 7.1 (or higher) Oracle Server, the initialization parameter DBLINK_ENCRYPT_LOGIN is set to TRUE, and you attempted to use a database link pointing to a version 7.0 (or lower) Oracle Server. 4) You are connected to a version 9.0.2(or higher) Oracle Server and you attempted to use a database link pointing to a version 9.0.1(or lower) Oracle Server for distributed autonomous transaction.
Action: For the above causes: 1) Do not use the invalid OCI operation. 2) If you do not wish to use encrypted connect passwords in your distributed database, set ORA_ENCRYPT_LOGIN to FALSE. If you wish to use encrypted connect passwords, you must upgrade all Oracle Servers to version 7.1 (or higher). 3) If you do not wish to use encrypted database links in your distributed database, set DBLINK_ENCRYPT_LOGIN to FALSE. If you wish to use encrypted database links, you must upgrade all Oracle Servers to version 7.1 (or higher). 4) Do not attempt distributed autonomous transaction on version 9.0.1(or lower) Oracle Server.

ORA-01151: use media recovery to recover block, restore backup if needed
Cause: Error 1172 occurred.
Action: This is additional information for error 1172.
ORA-01152: file string was not restored from a sufficiently old backup
Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the database consistent. This file is still in the future of the last log applied. The most likely cause of this error is forgetting to restore the file from a backup before doing incomplete recovery.
Action: Either apply more logs until the database is consistent or restore the database file from an older backup and repeat recovery.
ORA-01153: an incompatible media recovery is active
Cause: Attempted to start an incompatible media recovery or open resetlogs during media recovery or RMAN backup .

ORA-01156: recovery or flashback in progress may need access to files
Cause: Either media recovery, instance recovery, or flashback was in progress. The recovery or flashback in progress may need the files to which this operation is being applied.
Action: Wait for recovery or flashback to complete.
ORA-01157: cannot identify/lock data file string - see DBWR trace file
Cause: The background process was either unable to find one of the data files or failed to lock it because the file was already in use. The database will prohibit access to this file but other files will be unaffected. However the first instance to open the database will need to access all online data files. Accompanying error from the operating system describes why the file could not be identified.
Action: Have operating system make file available to database. Then either open the database or do ALTER SYSTEM CHECK DATAFILES.
ORA-01158: database string already mounted
Cause: Another instance has a database by this name mounted.
Action: Find which instance is still running. Perhaps you have not lost the control files after all.
ORA-01159: file is not from same database as previous files - wrong database id
Cause: Not all of the files specified in CREATE CONTROLFILE are from the same database. The database ID of this file does not match that from the first file specified.
Action: Please double check the list of files provided to the CREATE
ORA-01160: file is not a string
Cause: The named file in the DATAFILE or LOGFILE section of the CREATE CONTROLFILE command does not appear to be as stated.
Action: Please double check the mentioned file.
ORA-01161: database name string in file header does not match given name of string
Cause: The database name given at the command line does not match the database name found in the file header.
Action: Chance are good that the database name specified at the command line is incorrect. Resolve the descepency, and resubmit the command. If you are attempting to change the database name, be sure to use the SET DATABASE option.
ORA-01162: block size string in file header does not match configured block sizes
Cause: CREATE CONTROLFILE discovered that the block size for this file is incompatible with any of the configured cache blocksizes in the INIT.ORA file.
Action: Configure the appropriate cache for this block size using one of the various (db_2k_cache_size, db_4k_cache_size, db_8k_cache_size, db_16k_cache_size, db_32K_cache_size) parameters.
ORA-01163: SIZE clause indicates string (blocks), but should match header string
Cause: The size specified in bytes in the SIZE clause of the CREATE CONTROLFILE statement does not equate to the number of blocks recorded in the header.
Action: Specify the correct filename and size ( in bytes ).
ORA-01164: MAXLOGFILES may not exceed string
Cause: MAXLOGFILES specified on the command line too large.
Action: Resubmit the command with a smaller MAXLOGFILES
ORA-01165: MAXDATAFILES may not exceed string
Cause: MAXDATAFILES specified on the command line too large.
Action: Resubmit the command with a smaller MAXDATAFILES
ORA-01166: file number string is larger than string (string)
Cause: File mentioned in CREATE CONTROLFILE has a file number which is larger than that specified for MAXDATAFILES or MAXLOGFILES.
Action: Increase the maximum specified on the command line.
ORA-01167: two files are the same file/group number or the same file
Cause: There is an overlap of file numbers in the files specified on the command line or the same file is specified twice. If they are not the exact same file then one is likely to be a backup of the other. If they are two members of the same log they must be specified together in a group file spec. This message will also appear if the same control file appears more than once in the control_files parameter in the init.ora file. If this happens, check for additional error messages.
Action: Confirm that the file mentioned is not a repeat of a file already mentioned in the command. If they are different files then omit the earlier backup. If they are members of the same log, insure they are in the same group file specification. If this message appears because of a duplicate control file, check the control_files parameter in the init.ora file and see if a file is specified more than once. If all files names appear to be unique, check to make sure that the actual control files themselves are unique. For example, in UNIX check for a symbolic or a hard link to another control file in the list.
ORA-01168: physical block size string does not match size string of other members
Cause: The file is located on a device with a different physical block size than the other members in the group
Action: Use a physical device with matching block size.
ORA-01169: DATAFILE number 1 not found. Must be present
Cause: Datafile number 1 was not specified in a CREATE CONTROLFILE command.
Action: Locate datafile number 1 and resubmit the CREATE CONTROLFILE command.
ORA-01170: file not found 'string'
Cause: ALL datafiles and, if NORESETLOGS, ALL logfiles MUST be accessible by the process for CREATE CONTROLFILE.
Action: The file specified probably contains a typing error. Double check command and the existance of all files and then resubmit.
ORA-01171: datafile string going offline due to error advancing checkpoint
Cause: The checkpoint in the file header could not be advanced. See accompanying errors for the reason. The datafile will be taken offline the same as for a write error of a data block.
Action: See accompanying errors for details. Restore access to the file, do media recovery, and bring it back online.
ORA-01172: recovery of thread string stuck at block string of file string
Cause: Crash recovery or instance recovery could not apply a change to a block because it was not the next change. This can happen if the block was corrupted and then repaired during recovery.
Action: Do a RECOVER DATAFILE for the file containing the block. If this does not resolve the problem then restore the file from a backup and recover it.
ORA-01173: data dictionary indicates missing data file from system tablespace
Cause: Either the database has been recovered to a point in time in the future of the control file or a datafile from the system tablespace was omitted from the create control file command previously issued.
Action: For the former problem you need to recover the database from a more recent control file. For the latter problem, simply recreate the control file checking to be sure that you include all the datafiles in the system tablespace.
ORA-01174: DB_FILES is string buts needs to be string to be compatible
Cause: The maximum number of database files supported by this instance is not the same as for the other instances. All instances must be able to open all the files any instance can open.
Action: Change the value of the DB_FILES parameter to be compatible
ORA-01175: data dictionary has more than the string files allowed by the instance
Cause: The data dictionary is found to have more files than that which can be supported by this instance.
Action: Shutdown the instance and restart with a larger number of db_files
ORA-01176: data dictionary has more than the string files allowed by the controlfie
Cause: After a CREATE CONTROLFILE, the data dictionary was found to have more datafiles than that supported by the control file.
Action: Recreate the control file with a larger MAXDATAFILES.
ORA-01177: data file does not match dictionary - probably old incarnation
Cause: When comparing the control file with the data dictionary after a CREATE CONTROLFILE or OPEN RESETLOGS, it was noted that this datafile was inconsistent with the dictionary. Most likely the file is a backup of a file that was dropped from the database, and the same file number was reused for a new file. It may also be that an incomplete recovery stopped at a time when this file number was used for another datafile.
Action: Do a CREATE CONTROLFILE with the correct file or none at all.
ORA-01178: file string created before last CREATE CONTROLFILE, cannot recreate
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that existed at the last CREATE CONTROLFILE command. The information needed to recreate the file was lost with the control file that existed when the file was added to the database.
Action: Find a backup of the file, and recover it. Do incomplete recovery to time before file was originally created.
ORA-01179: file string does not exist
Cause: During datafile recovery, a file was listed which was not part for the database.
Action: Recheck the datafile name. Remember to use double quotes at the SQLDBA command line and remember that the file name is translated in the environment of the SQLDBA.
ORA-01180: can not create datafile 1
Cause: Attempting to create datafile 1 using ALTER DATABASE CREATE DATAFILE.
Action: Recover file from a backup or recreate database.
ORA-01181: file string created before last known RESETLOGS, cannot recreate
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that existed before the last known RESETLOGS.
Action: Find a backup of the file, and recover it. Do incomplete recovery to time before file was originally created.
ORA-01182: cannot create database file string - file is in use or recovery
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that is online in an open instance or is being recovered.
Action: Close database in all instances and end all recovery sessions
ORA-01183: cannot mount database in SHARED mode
Cause: Some other instance has the database mounted exclusive.
Action: Shutdown other instance then mount shared.
ORA-01184: logfile group string already exists
Cause: An ALTER DATABASE ADD LOGFILE command specified a log number for the new log which is already in use.
Action: Specify a different logfile number, or let the database choose an unused value.
ORA-01185: logfile group number string is invalid
Cause: An ALTER DATABASE ADD LOGFILE command specified a log number for the new log which is too large.
Action: Specify a correct logfile number.
ORA-01186: file string failed verification tests
Cause: The data file did not pass the checks to insure it is part of the database. See the accompanying error messages for the reason the verification failed.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.
ORA-01187: cannot read from file string because it failed verification tests
Cause: The data file did not pass the checks to insure it is part of the database. Reads are not allowed until it is verified.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.
ORA-01188: The block size specified string does not match header block size string
Cause: The block size specified in the BLOCKSIZE clause of the CREATE CONTROLFILE statement does not equate to the block size recorded in the log file header.
Action: Specify the correct block size.
ORA-01189: file is from a different RESETLOGS than previous files
Cause: In a CREATE CONTROLFILE command either this file or all previous files were backups from before the last RESETLOGS. This may also occur if this is a file that is offline and has been offline since before the last RESETLOGS.
Action: If the file was taken offline normal before the last RESETLOGS, and is still offline, omit it from the CREATE CONTROLFILE command. Rename and online the file after the database is open. Otherwise find the version of the mentioned file consistent with the rest of the datafiles and resubmit the command.
ORA-01190: control file or data file string is from before the last RESETLOGS
Cause: Attempting to use a data file when the log reset information in the file does not match the control file. Either the data file or the control file is a backup that was made before the most recent ALTER DATABASE OPEN RESETLOGS.
Action: Restore file from a more recent backup.
ORA-01191: file string is already offline - cannot do a normal offline
Cause: When attempting to do a normal tablespace offline it was discovered that one of the files in the tablespace was already offline.
Action: Either bring the datafile online first, or use another tablespace offline option.
ORA-01192: must have at least one enabled thread
Cause: You must specify at least two logfiles from at least one thread at the create contolfile command line.
Action: Find the missing logfiles and resubmit the command with the newly found logfiles included in the command line.
ORA-01193: file string is not the same file seen at start of recovery
Cause: A different copy of the file was accessed the last time media recovery looked at the file header. A backup of the file was restored or the meaning of the file name changed during recovery.
Action: Ensure the correct file is available, then retry recovery.
ORA-01194: file string needs more recovery to be consistent
Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the file consistent. The reported file was not closed cleanly when it was last opened by the database. It must be recovered to a time when it was not being updated. The most likely cause of this error is forgetting to restore the file from a backup before doing incomplete recovery.
Action: Either apply more logs until the file is consistent or restore the file from an older backup and repeat recovery.
ORA-01195: online backup of file string needs more recovery to be consistent
Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the file consistent. The reported file is an online backup which must be recovered to the time the backup ended.
Action: Either apply more logs until the file is consistent or restore the database files from an older backup and repeat recovery.
ORA-01196: file string is inconsistent due to a failed media recovery session
Cause: The file was being recovered but the recovery did not terminate normally. This left the file in an inconsistent state. No more recovery was successfully completed on this file.
Action: Either apply more logs until the file is consistent or restore the backup again and repeat recovery.
ORA-01197: thread string only contains one log
Cause: During CREATE CONTROLFILE all threads represented in the logs must be represented by at least two logs. A "last log" and a second log. The named thread does not contain two such logs.
Action: Either find more logs from the named thread. Or use the RESETLOGS option to CREATE CONTROLFILE.
ORA-01198: must specify size for log file if RESETLOGS
Cause: File sizes must be given for all logfiles if doing a CREATE CONTROLFILE with the RESETLOGS option.
Action: Resubmit the command with the appropriate logfile size.
ORA-01199: file string is not in online backup mode
Cause: Attempting to end an online backup for a file that is not in online backup.
Action: Do not enter command since it is not needed.
ORA-01200: actual file size of string is smaller than correct size of string blocks
Cause: The size of the file as returned by the operating system is smaller than the size of the file as indicated in the file header and the control file. Somehow the file has been truncated. Maybe it is the result of a half completed copy.
Action: Restore a good copy of the data file and do recovery as needed.
ORA-01201: file string header failed to write correctly
Cause: An I/O error was reported for the file header. The error was trapped and a second attempt will be made.
Action: The file probably will require recovery. Further error messages will indicate what is needed.
ORA-01202: wrong incarnation of this file - wrong creation time
Cause: The creation time in the file header is not the same as the creation time in the control file. This is probably a copy of a file that was dropped.
Action: Restore a current copy of the data file and do recovery as needed.
ORA-01203: wrong incarnation of this file - wrong creation SCN
Cause: The creation SCN in the file header is not the same as the creation SCN in the control file. This is probably a copy of a file that was dropped.
Action: Restore a current copy of the data file and do recovery as needed.
ORA-01204: file number is string rather than string - wrong file
Cause: The file number in the file header is not correct. This is probably a restored backup of the wrong file, but from the same database.
Action: Restore a copy of the correct data file and do recovery as needed.
ORA-01205: not a data file - type number in header is string
Cause: The file type in the header is not correct for a data file. This is probably a log file or control file. If the type is not a small non-zero positive number then the header is corrupted.
Action: Restore a copy of the correct data file and do recovery as needed.
ORA-01206: file is not part of this database - wrong database id
Cause: The database ID in the file header does not match the database id in the control file. The file may be from a different database, or it may not be a database file at all. If the database was rebuilt, this may be a file from before the rebuild. Note that if you see this error when the file is supposed to be plugged in from another database via the Transportable Tablespace feature, it means the database ID in the file header does not match the one expected.
Action: Restore a copy of the correct data file and do recovery as needed.
ORA-01207: file is more recent than control file - old control file
Cause: The control file change sequence number in the data 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-01208: data file is an old version - not accessing current version
Cause: The checkpoint in the file header is less recent than in the control file. If opening a database that is already open by another instance, or if another instance just brought this file online, the file accessed by this instance is probably a different version. Otherwise, a backup of the file probably was restored while the file was in use.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.
ORA-01209: data file is from before the last RESETLOGS
Cause: The reset log data in the file header does not match the control file. If the database is closed or the file is offline, the backup is old because it was taken before the last ALTER DATABASE OPEN RESETLOGS command. If opening a database that is open already by another instance, or if another instance just brought this file online, the file accessed by this instance is probably a different version. Otherwise, a backup of the file probably was restored while the file was in use.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.
ORA-01210: data file header is media corrupt
Cause: The file header block is internally inconsistent. The beginning of the block has a header with a checksum and other data for insuring the consistancy of the block. It is possible that the last disk write did not operate correctly. The most likely problem is that this is not a datafile for any database.
Action: Have operating system make correct file available to database. If the trace file dump indicates that only the checksum is wrong, restore from a backup and do media recovery.
ORA-01211: Oracle7 data file is not from migration to Oracle8
Cause: The file is not a copy of the file LAST used under Oracle7. This datafile is either a backup taken from before the migration, or the database was opened by Oracle7 after the migration utility was run. When converting a database from Oracle7 to Oracle8, the migration program MUST be the LAST utility to access the database under Oracle7. Only the datafiles that were current when the migration was done may be accessed by Oracle8.
Action: Have operating system make correct data file available to database, or repeat the Oracle7 to Oracle8 migration. Make sure that database is NOT opened after migration utility is run.
ORA-01212: MAXLOGMEMBERS may not exceed string
Cause: MAXLOGMEMBERS specified on the command line too large.
Action: Resubmit the command with a smaller MAXLOGMEMBERS
ORA-01213: MAXINSTANCES may not exceed string
Cause: MAXINSTANCES specified on the command line too large.
Action: Resubmit the command with a smaller MAXINSTANCES
ORA-01214: MAXLOGHISTORY may not exceed string
Cause: MAXLOGHISTORY specified on the command line too large.
Action: Resubmit the command with a smaller MAXLOGHISTORY
ORA-01215: enabled thread string is missing after CREATE CONTROLFILE
Cause: A CREATE CONTROLFILE statement was given which did not list all the enabled threads for the database.
Action: Reissue the CREATE CONTROLFILE statement, including all enabled threads.
ORA-01216: thread string is expected to be disabled after CREATE CONTROLFILE
Cause: A thread that was given during CREATE CONTROLFILE is enabled, but the datafiles indicate that it should be disabled. This is probably because the logs supplied to the CREATE CONTROLFILE are old (from before the disabling of the thread).
Action: This thread is not required to run the database. The CREATE CONTROLFILE statement can be reissued without the problem thread, and, if desired, the thread can be recreated after the database is open.
ORA-01217: logfile member belongs to a different logfile group
Cause: A member of a multiple-member logfile group specified in a CREATE CONTROLFILE is not part of the same group as previous members.
Action: Group together the correct members for the CREATE CONTROLFILE command.
ORA-01218: logfile member is not from the same point-in-time
Cause: A member of a multiple-member logfile group is from a different point in time. One of the members specified may be an older (backup) copy of the log.
Action: Find the correct version of the log, or leave it out of the CREATE CONTROLFILE command.
ORA-01219: database not open: queries allowed on fixed tables/views only
Cause: A query was issued against an object not recognized as a fixed table or fixed view before the database has been opened.
Action: Re-phrase the query to include only fixed objects, or open the database.
ORA-01220: file based sort illegal before database is open
Cause: A query issued against a fixed table or view required a temporary segment for sorting before the database was open. Only in-memory sorts are supported before the database is open.
Action: Re-phrase the query to avoid a large sort, increase the values of the SORT_AREA_SIZE and/or SORT_AREA_RETAINED_SIZE initialization parameters to enable the sort to be done in memory.
ORA-01221: data file string is not the same file to a background process
Cause: When the database writer opens the data file, it is accessing a different physical file than the foreground doing the recovery. The timestamp set in the file header by the foreground was not found by the background. It may be that the background process could not read the file at all.
Action: Look in the DBWR trace file for the error it recieved when attempting to read the file header. Reconfigure the operating system as needed to have the file name successfully access the same file when opened by a background process.
ORA-01222: MAXINSTANCES of string requires MAXLOGFILES be at least string, not string
Cause: Attemping to create a database or control file that does not have room for at least two logs per thread of redo. A thread of redo must have two online logs in order to be enabled. It does not make sense to allow more redo threads than can be supported by the logs.
Action: Either reduce the MAXINSTANCES argument or increase MAXLOGFILES.
ORA-01223: RESETLOGS must be specified to set a new database name
Cause: The SET database name option was specified to CREATE CONTROLFILE, but RESETLOGS was not specified. The database name can only be changed when opening the database with RESETLOGS.
Action: Either add the RESETLOGS option or drop the SET option to CREATE CONTROLFILE.
ORA-01224: group number in header string does not match GROUP string
Cause: Group number specified at CREATE CONTROLFILE does not match the group number stored in the header. Most likely the specification is wrong.
Action: Omit the GROUP option or give the correct one.
ORA-01225: thread number string is greater than MAXINSTANCES string
Cause: The log is for a thread greater than the MAXINSTANCES argument.
Action: Increase the value for MAXINSTANCES and resubmit the command.
ORA-01226: file header of log member is inconsistent with other members
Cause: The log file member in the accompanying error is for the same group as the previous members, but other fields in the header are different. Either a file header is corrupted, or some file is a member of a deleted log.
Action: Find the correct log member or omit this member from the command.
ORA-01227: log string is inconsistent with other logs
Cause: The log file in the accompanying error is inconsistent with the contents of other logs given in the CREATE CONTROLFILE command. Either a file header is corrupted, or some file is an old copy rather than the current version. The problem may not be with the log listed since all that can be detected is that there is an inconsistancy. All log files listed in the command must be the current versions of the online logs.
Action: Find the correct online logs or use the RESETLOGS option.
ORA-01228: SET DATABASE option required to install seed database
Cause: The SET DATABASE option was not included in the CREATE CONTROLFILE command when installing a seed database. The database does not have a database ID because it is intended to be installed at multiple sites, and each site needs to be a different database with its own database id. Both the SET DATABASE and RESETLOGS options must be specified to create the control file for this database.
Action: Resubmit command with the SET DATABASE and RESETLOGS options.
ORA-01229: data file string is inconsistent with logs
Cause: The data file in the accompanying error is inconsistent with the contents of the logs given in the CREATE CONTROLFILE command. The most likely cause is that one or more of the online logs was missing from the command. It is also possible that one or more of the logs is an old copy rather than the current version. All online log files must be listed in the command and must be the current versions of the online logs.
Action: Find the correct online logs or use the RESETLOGS option.
ORA-01230: cannot make read only - file string is offline
Cause: An attempt to make a tablespace read only found that one of its files is offline.
Action: Bring the file online and retry this command.
ORA-01231: cannot make read write - file string is offline
Cause: An attempt to make a tablespace read write found that one of its files is offline.
Action: Bring the file online and retry this command.
ORA-01232: cannot start online backup - file string is being made read-only
Cause: An attempt to start an online backup found that one of the files is in transition to read-only mode.
Action: Wait for the transition to complete and then retry the command, if this is an ALTER DATABASE BEGIN BACKUP command, or take the backup without any begin or end commands, if this is an ALTER TABLESPACE BEGIN BACKUP command.
ORA-01233: file string is read only - cannot recover using backup control file
Cause: An attempt to do media recovery using a backup control file found that one of the files is marked read only. Read only files do not normally need to be recovered, but recovery with a backup control file must recover all online files.
Action: If the file really is read only, take it offline before the recovery, and bring the read only tablespace online after the database is open. If the file does need recovery use a control file from the time the file was read-write. If the correct control file is not available, use CREATE CONTROLFILE to make one.
ORA-01234: cannot end backup of file string - file is in use or recovery
Cause: Attempted to end an online backup of file when the file is busy. Some operation such as recovery or rename may be active, or there may still be some instance that has the database open with this file online.
Action: If there is an instance with the database open then the backup can be ended there by using the ALTER TABLESPACE command. Otherwise wait for the completion of the other operation.
ORA-01235: END BACKUP failed for string file(s) and succeeded for string
Cause: One or more of the files in an end backup command failed. Some other files given in the same command may have succeeded.
Action: See the accompanying error messages for the reason the backups could not be ended. Any files not listed in the error messages were successful.
ORA-01236: Error string occurred during initialization of file header access
Cause: The indicated error occurred while doing initialization processing of file headers.
Action: The error indicated should be corrected. An attempt is made to recover from this error by using a slower access algorithm.
ORA-01237: cannot extend datafile string
Cause: An operating system error occurred during the resize.
Action: Fix the cause of the operating system error and retry the command.
ORA-01238: cannot shrink datafile string
Cause: An operating system error occurred during the resize.
Action: The error is ignored, operation continues normally.
ORA-01239: database must be in ARCHIVELOG mode to use external cache
Cause: An online file uses an external cache, but the database is in NOARCHIVELOG mode. Since an external cache may require media recovery this can not be allowed.
Action: Change database to be in ARCHIVELOG mode or do not use an external cache.
ORA-01240: too many data files to add in one command
Cause: The command specifies adding more data files than can be done in one command. It is necessary to fit all the file names into one log entry, but that would make the entry too large.
Action: If this is a CREATE TABLESPACE command, create with fewer files then add the other files later. If this is an ADD DATAFILE command, break it up into multiple commands.
ORA-01241: an external cache has died
Cause: The external cache may have been restarted.
Action: Take the file mentioned in the error stack offline, perform media recovery, bring the file online, and retry the attempted operation. You may also restart all instances to make sure they access all data files through consistent external caches.
ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode
Cause: The database is in NOARCHIVELOG mode and a database file was detected as inaccessible due to media failure.
Action: Restore accessibility to the file mentioned in the error stack and restart the instance.
ORA-01243: system tablespace file suffered media failure
Cause: A system tablespace file was detected as inaccessible due to media failure.
Action: Restore accessibility to the file mentioned in the error stack and restart the instance.
ORA-01244: unnamed datafile(s) added to control file by media recovery
Cause: Media recovery with a backup control file or a control file that was rebuilt, encountered the creation of a datafile that was not in the control file. An entry has been added to the control file for the new datafiles, but with the file name UNNAMEDnnnn, where nnnn is the file number. Attached errors describe the file names that were originally used to create the files.
Action: Rename the files to valid file names and resume recovery. If necessary the command ALTER DATABASE CREATE DATAFILE may be used to create a file suitable for recovery and do the rename. If the file is not going to be recovered then take it offline with the FOR DROP option.
ORA-01245: offline file string will be lost if RESETLOGS is done
Cause: Attempting to do an OPEN RESETLOGS with a file that will be lost because it is offline. The file was not taken offline with the FOR DROP option.
Action: Either bring the file online and recover it, or take it offline with the FOR DROP option.
ORA-01246: recovering files through TSPITR of tablespace string
Cause: The files named in the accompanying errors are backups that were made before a tablespace point in time recovery of this tablespace. They cannot be recovered to a time after the point in time recovery.
Action: Restore more recent backups and recover them.
ORA-01247: database recovery through TSPITR of tablespace string
Cause: Recovery of the whole database encountered redo indicating there was a point in time recovery of the tablespace. The new version of the files in the tablespace should be included in the recovery, but that was not done.
Action: If the tablespace should not be recovered, take its file offline for drop. If it should be recovered, then restore or rename as needed and restart the recovery.
ORA-01248: file string was created in the future of incomplete recovery
Cause: Attempting to do a RESETLOGS open with a file entry in the control file that was originally created after the UNTIL time of the incomplete recovery. Allowing such an entry may hide the version of the file that is needed at this time. The file number may be in use for a different file which would be lost if the RESETLOGS was allowed.
Action: If more recovery is desired then apply redo until the creation time of the file is reached. If the file is not wanted and the same file number is not in use at the stop time of the recovery, then the file can be taken offline with the FOR DROP option. Otherwise a different control file is needed to allow the RESETLOGS. Another backup can be restored and recovered, or a control file can be created via CREATE CONTROLFILE.
ORA-01249: archiving not allowed in a clone database
Cause: Attempting to archive an online redo log or enable archiving for a clone database.
