By default, there is not any archived redo log deletion coverage and this is why the archive redo log coverage is about for the NONE clause. In this particular certain scenario, the rapid recovery space considers archived redo log files inside the Restoration location as eligible for deletion if they are actually backed up not less than as soon as to disk or SBT or even the logs are obsolete according to the backup retention policy.

If your backup and restore functions triumph, Then you certainly are willing to make use of the media manager with RMAN. Attainable failures involve the next scenarios:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR Unit Style sbt Obvious; In case you have build a fast Restoration space with the databases, Then you can certainly direct Manage file autobackups to the rapid recovery location by clearing the Management file autobackup format for disk.
Your media supervisor could impose restrictions on file names and measurements. In this instance, you may need additional Handle in excess of the naming of backup pieces so they obey media manager limits.
