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
