Cause: An error occurred earlier during CONVERT DATABASE operation.
Action: Retry CONVERT DATABASE command.

ORA-19930: file string has invalid checkpoint SCN string
Cause: When opening the file to be placed in a copy or backup set, to be inspected, the file header was not recognized as a valid header because it contained a invalid checkpoint SCN. The indicated file cannot be processed.
Action: Ensure that the correct files are being specified for the catalog or backup operation.

ORA-19931: file string has invalid creation SCN string
Cause: When opening the file to be placed in a copy or backup set, to be inspected, the file header was not recognized as a valid header because it contained a invalid creation SCN. The indicated file cannot be processed.
Action: Ensure that the correct files are being specified for the catalog or backup operation.

ORA-19932: control file is not clone or standby
Cause: The operation failed because the control file was not mounted as standby or clone.
Action: Mount the database as standby or clone and retry.

ORA-19941: invalid blocksize in cross platform datafile string
Cause: Blocksize in header of datafile copy being converted at target was invalid. Either datafile has not been made read/write with compatibility 10.0 or greater at source database or datafile copy is corrupted.
Action: Make a new datafile copy taken after tablespace has been made read/write with compatibility 10.0 at source database and retry conversion.

ORA-19942: datafile copy string not created with compatibility 10.0 or greater
Cause: The specified datafile copy to be converted at the target was not produced after making the tablespace in read/write mode with compatibility 10.0 or greater at the source database.
Action: Make a new datafile copy taken after tablespace has been made read/write with compatibility 10.0 at source database and retry conversion.

ORA-19943: The current database incarnation changed during backup
Cause: The backup failed because the current database incarnation was changed during the backup. One of the following events caused this incarnation change:
- The database was opened using ALTER DATABASE OPEN RESETLOGS statement.
- RMAN command RESET DATABASE TO INCARNATION was issued.
- If this happened on physical standby database, then redo apply has applied redo data from a new database incarnation.
Action: Re-try the backup.

ORA-19951: cannot modify control file until DBNEWID is completed
Cause: An operation requiring to modify the control file was attempted, but a NID change is in progress.

Cause: The database was started in parallel mode. To change the DBID, the database must be mounted exclusively.
Action: Shut down the database and start it in exclusive mode.

ORA-19953: database should not be open
Cause: The database was open. To change the DBID, the database must be mounted exclusively.
Action: Shut down the database and mount it in exclusive mode.

ORA-19954: control file is not current
Cause: The operation failed because a non-current, non-standby control file was mounted.
Action: Make the control file current and retry.

ORA-19955: only one open thread is allowed to change the DBID
Cause: The operation failed because there were active threads in the database. The most likely cause is that the database crashed the last time it was shut down.
Action: Ensure that all threads are closed before retrying the operation. Start and open the database to perform crash recovery, then shut down with the NORMAL or IMMEDIATE options to close it cleanly. Finally, try running the utility again.

ORA-19956: database should have no offline immediate datafiles
Cause: The operation failed because the database had one or more datafiles that were in OFFLINE IMMEDIATE mode.
Action: Drop the datafiles or recover them and bring them online.

ORA-19957: database should have no datafiles in unknown state
Cause: The operation failed because the database had one or more datafiles that were in an unknown state.
Action: Drop the datafiles or recover them and bring them online.

ORA-19958: potential deadlock involving DIAG process
Cause: DIAG requested a control file operation that may lead to a deadlock
Action: Try last operation later when the control file is released

ORA-19960: Internal use only
Cause: NID usage
Action: None
ORA-19999: skip_row procedure was called

ORA-21300: objects option not installed
Cause: The objects option is not installed at this site. object types and other object features are, therefore, unavailable.
Action: Install the objects option. The objects option is not part of the Oracle Server product and must be purchased separately. Contact an Oracle sales representative if the objects option needs to be purchased.

ORA-21301: not initialized in object mode
Cause: This function requires the OCI process to be initialized in object mode.
Action: Specify OCI_OBJECT mode when calling OCIInitialize().

ORA-21500: internal error code, arguments: [string], [string], [string], [string], [string], [string], [string], [string]
Cause: This is the generic error number for the OCI environment (client-side) internal errors. This indicates that the OCI environment has encountered an exceptional condition.
Action: Report as a bug - the first argument is the internal error number.

ORA-21501: program could not allocate memory
Cause: The operating system has run out of memory.
Action: Take action to make more memory available to the program.

ORA-21503: program terminated by fatal error
Cause: A program is in an unrecoverable error state.
Action: Report as a bug.

ORA-21520: database server driver not installed
Cause: User attempted to access a database server through an object-mode OCI environment but the necessary driver for supporting such access to the database server is not installed or linked in.

Action: Check the type of the object and correct it.

ORA-21525: attribute number or (collection element at index) string violated its constraints
Cause: Attribute value or collection element value violated its constraint.
Action: Change the value of the attribute or collection element such that it meets its constraints. The constraints are specified as part of the attribute or collection element's schema information.

ORA-21526: initialization failed
Cause: The initialization sequence failed. This can happen, for example, if an environment variable such as NLS_DATE_FORMAT is set to an invalid value.
Action: Check that all NLS environment variables are well-formed.

ORA-21527: internal OMS driver error
Cause: A process has encountered an exceptional condition. This is the generic internal error number for Oracle object management services exceptions.
Action: Report this as a bug to Oracle Support Services.

ORA-21560: argument string is null, invalid, or out of range
Cause: The argument is expecting a non-null, valid value but the argument value passed in is null, invalid, or out of range. Examples include when the LOB/FILE positional or size argument has a value outside the range 1 through (4GB - 1), or when an invalid open mode is used to open a file, etc.
Action: Check your program and correct the caller of the routine to not pass a null, invalid or out-of-range argument value.

ORA-21561: OID generation failed
Cause: The handles passed in may not be valid
Action: Check the validity of the env, svc handles

ORA-21600: path expression too long
Cause: The path expression that is supplied by the user is too long. The path expression is used to specify the position of an attribute in an object. This error occurs when one of the intermediate elements in the path expression refers to an attribute of a built-in type. Thus, the OCI function cannot proceed on to process the rest of the elements in the path expression.
Action: User should pass in the correct path expression to locate the attribute.

ORA-21601: attribute is not an object
Cause: The user attempts to perform an operation (that is valid only for an object) to an attribute of a built-in type. An example of such an illegal operation is to dynamically set a null structure to an attribute of a built-in type.
Action: User should avoid performing such operation to an attribute of built-in type.

ORA-21602: operation does not support the specified typecode
Cause: The user attempts to perform an operation that does not support the specified typecode.
Action: User should use the range of valid typecodes that are supported by this operation.

ORA-21603: property id [string] is invalid
Cause: The specified property id is invalid.
Action: User should specify a valid property id. Valid property ids are enumerated by OCIObjectPropId.

Cause: Could not obtain the connect string from the target database
Action: Check the accompanying errors.

ORA-19860: piece validation cannot be performed more than once
Cause: The user attempted to validate a list of backup pieces more than once. Validation may only be performed once for a given validation conversation.
Action: Do not attempt to validate the pieces more than once.

ORA-19861: additional backup pieces cannot be validated in this conversation
Cause: The user tried to add new pieces to the list of files being validated after the validation had already been performed. In a validation conversation, the list can only be validated once.
Action: Add all the backup pieces to the list before validating, or start a new validation conversation for the remaining pieces.

ORA-19862: backup pieces must be validated before accessing results
Cause: The user tried to get validation results for backup pieces before the pieces were actually validated.
Action: Validate the pieces before trying to access the results.

ORA-19863: device block size string is larger than max allowed: string
Cause: The user specified a device BLKSIZE that is larger than the device BLKSIZE specified during compressed backup.
Action: Change the device BLKSIZE to be smaller than the maximum allowed.

ORA-19865: Backup piece string has no data
Cause: No data was returned for the specified backup piece.
Action: This normally indicates a problem with the media management software which is linked with Oracle to provide backup and restore services. Contact the media management software vendor.

ORA-19866: error writing file header for datafile string
Cause: During a block recovery, the header of the datafile could not be updated.
Action: Contact Oracle Support Services.

ORA-19870: error while restoring backup piece string
Cause: This error should be followed by other errors indicating the cause of the problem.
Action: See other errors actions.

ORA-19873: cannot apply this backup section to file string
Cause: RMAN cannot restore a multi-section backup to the indicated file, because this section is not a backup of this file, or the file was not prepared correctly for this restore.
Action: If this error occurs while running RMAN, then it is an internal error and you should contact Oracle support.

ORA-19874: cannot finish multi-section restore to file string
Cause: During a multi-section restore, the file being restored is not a file in which a multi-section restore is in progress.
Action: If this error occurs while running RMAN, then it is an internal error and you should contact Oracle support.

ORA-19875: multi-section restore not complete for file string
Cause: While completing a multi-section restore, it was found that all required sections for this file were not correctly applied.
Action: If this error occurs while running RMAN, then it is an internal error and you should contact Oracle support.

ORA-19880: Corrupted space header for datafile string, block string
Cause: When reading the space header block to use Unused Block Optimization for the backup of the datafile, the space header block had corrupted information.
Action: The corrupt space header must be fixed before Unused Block Optimization can be used for this file. Note that you should fix the corruption in any case because it will affect the availability of the data in the file, beyond just taking backups.

ORA-19881: Corrupted space bitmap for datafile string, block string
Cause: When reading a space bitmap block to use Unused Block Optimization for the backup of the datafile, the space bitmap block had corrupted information.
Action: The corrupt space bitmap must be fixed before Unused Block Optimization can be used for this file. Note that you should fix the corruption in any case because it will affect the availability of the data in the file, beyond just taking backups.

ORA-19882: datafile string checkpoint string is ahead of space bitmap datafile string checkpoint string
Cause: When checkpointing the datafile containing the space bitmaps for the datafile being backed up in order to use Unused Block Optimization, the checkpoint of the datafile containing the space bitmaps did not advance.
Action: Examine the trace and alert files for possible causes. Fix underlying problem to use Unused Block Optimization for datafile's backup.

ORA-19883: Unused Block Optimization stopped for datafile string
Cause: Accompanying errors detail the problem that prevented Unused Block Optimization from being used.
Action: See accompanying errors for appropiate action.

ORA-19900: RESETLOGS must be specified after recovery to new incarnation
Cause: Recovery was done to an incarnation after changing the destination incarnation using RMAN's RESET DATABASE command.
Action: Open the database with the RESETLOGS option.

ORA-19901: database needs more recovery to create new incarnation
Cause: Recovery was done to an incarnation after changing the destination incarnation using RMAN's RESET DATABASE command, but one or more of the recovered datafiles still belongs to the parent incarnation. This usually happens when recovery is ended before any logs from the desired incarnation have been applied.
Action: Continue recovery.

ORA-19902: incarnation key string not found
Cause: The specified incarnation was not found in the control file.
Action: Resubmit request with known incarnation key. To see which incarnations are available for this target database, query V$DATABASE_INCARNATION or use RMAN's LIST INCARNATION command.

ORA-19903: test recovery not allowed when recovering to new incarnation
Cause: Either a new incarnation was set using RMAN's RESET DATABASE command for a control file that was CURRENT, or the control file is from a prior incarnation. As recovery to a new incarnation requires changing the control file, test recovery is not allowed.
Action: Perform actual recovery or RESET DATABASE to incarnation that was last opened using the control file to do test recovery.

ORA-19904: test recovery not allowed for datafile string
Cause: The specified datafile has been restored from a backup that was taken before the last RESETLOGS. Recovering this datafile will require a file header update that is incompatible with test recovery.
Action: Perform actual recovery.

ORA-19905: log_archive_format must contain %s, %t and %r
Cause: log_archive_format is missing a mandatory format element. Starting with Oracle 10i, archived log file names must contain each of the elements %s(sequence), %t(thread), and %r(RESETLOGS ID) to ensure that all archived log file names are unique.
Action: Add the missing format elements to log_archive_format.

ORA-19906: recovery target incarnation changed during recovery
Cause: While a media recovery was active, a new incarnation was detected by the server due to inspection or cataloging of archived logs or backup files.
Action: If you want recovery to use the new incarnation, restart recovery. This is the most common action on a standby database when RESETLOGS is done in primary. If you do not want recovery to use the new incarnation, change the recovery destination using RMAN's RESET DATABASE TO INCARNATION <incarnation#> command. To see which incarnations are available for this target database, query V$DATABASE_INCARNATION or use RMAN's LIST INCARNATION command.

ORA-19907: recovery time or SCN does not belong to recovered incarnation
Cause: A point-in-time recovery to an SCN or time stamp prior to the last RESETLOGS was requested.
Action: Either change the specified recovery time/SCN, or change the recovery destination using RMAN's RESET DATABASE command.

ORA-19908: datafile string has invalid checkpoint
Cause: The specified datafile has an invalid checkpoint.
Action: Restore the datafile from a backup.

ORA-19909: datafile string belongs to an orphan incarnation
Cause: Either the specified datafile was restored from a backup that was taken during a period of time that has already been discarded by a RESETLOGS operation, or Oracle cannot identify which database incarnation the file belongs to. The alert log contains more information.
Action: Restore a backup of this file that belongs to either the current or a prior incarnation of the database. If you are using RMAN to restore, RMAN will automatically select a correct backup.

ORA-19910: can not change recovery target incarnation in control file
Cause: The RESET DATABASE TO INCARNATION command was used while the database is open. This is not allowed.
Action: Close the database then re-issue the command.

ORA-19911: datafile string contains future changes at the incarnation boundary
Cause: The file did not hit end backup marker redo during recovery at the incarnation boundary, hence may contain changes discarded by new incarnation.
Action: Use older backup of the file and then re-issue the command.

ORA-19912: cannot recover to target incarnation string
Cause: The control file is not in the recovery path of the target incarnation, and does not contain enough information as to how to recover to the target incarnation.
Action: Restore the latest control file from the target incarnation and retry.

ORA-19913: unable to decrypt backup
Cause: A backup piece could not be decrypted. This message is accompanied with another message that indicates the name of the encrypted backup that could not be restored. The reason could be either that an invalid password was entered, or that, when using transparent decryption, the database external security device is not open.
Action: If password-based restore was enabled for this backup, then supply the correct password using the RMAN SET DECRYPTION command. If transparent restore was enabled for this backup, then ensure that the database external security device is open.

ORA-19914: unable to encrypt backup
Cause: RMAN could not create an encrypted backup. This message will be accompanied by other messages that give more details about why the encrypted backup could not be created. The most common reason for this message is that you are trying to create a backup that can be transparently decrypted, and the database external security device is not open.
Action: If the external security device is not open, then open it. If the external security device is not configured, then the only type of encrypted backup that you can create is a password-based backup.

ORA-19915: unable to encrypt pre-10.2 files
Cause: An RMAN encrypted backup was requested, but this backup includes one or more archived logs that were generated by an older release of Oracle. These archived logs cannot be encrypted.
Action: Back up the older logs without encryption. Logs created with Oracle release 10.2 and greater can be encrypted.

ORA-19916: string
Cause: An error occurred when processing user request.
Action: Do not use message 19917; it is used internally for testing purpose. Do not use message 19918; it is an internal event used by encryption.

ORA-19919: encrypted backups to tertiary storage require Oracle Secure Backup
Cause: RMAN was configured to create encrypted backups, but the channel is neither a DISK channel nor an Oracle Secure Backup channel.
Action: Allocate a DISK channel or an Oracle Secure Backup channel to use backup encryption.

ORA-19921: maximum number of string rows exceeded
Cause: The maximum number of rows in the V$RMAN_STATUS or V$RMAN_OUTPUT table has been exceeded.
Action: Close some of existing and unused RMAN connections and sessions.
