NetBackup status code: 5457
Message: Database must not contain any data files that are in backup mode.
Explanation: Moving data files in and out of backup mode is not necessary with OIP RMAN-based NetBackup protection. Leaving a file in backup mode produces the following warning during the RMAN backup but does not fail the operation:
RMAN-06554: WARNING: file string is in backup mode Cause: A file which is being backed up or copied is in backup mode. RMAN will back up the file anyway, but files do not need to be put into backup mode before backing them up with RMAN. Action: Use the ALTER TABLESPACE ... END BACKUP statement, at the target database server, to take the files out of backup mode. Oracle Support Document 2016401.1 (RMAN-06554: WARNING: file x is in backup mode)
By leaving a data file in backup mode, transactions for that data file are offloaded into archive logs if ARCHIVELOG mode is enabled. These archive logs can possibly grow to an unreasonable size and cause system instability. If no archive log backups are ever taken, data loss is possible if a restore is expected at a specific point in time.
Recommended Action: NetBackup fails any jobs where Oracle data files are detected to be in backup mode. Take the affected data file out of backup mode and re-run the backup.
