Oracle Database Errors or Warnings from Error ORA-00251 to ORA-00260
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.
