Oracle RMAN Restore and Recovery

Oracle Restore Enhancements

Starting with Oracle 10g Release 2, Data Protector includes a series of enhancements to improve
restore performance. Additional attributes (SBTBFINFO flags) are now set for each backup file:
• Data Protector Tape device concurrency: This allows more than one RMAN channel to read from
the same device
• Backup file sequence: Files should be read in the same sequence they are physically on the media
• Media ID stored in the recovery catalog: This enables oracle processes to optimize restores by
avoiding the restore of files in the same tape at the same time.
As it can be seen in the following RMAN list command, now the Media ID is stored in the recovery
catalog and can be queried:
