Let us we discuss the topic DB Point-in-time recovery using RMAN Backup Archivelog List Commands delete archivelog all; delete archivelog until time 'SYSDATE-1'; delete archivelog from time 'SYSDATE-1' . Please allocate channels and set the archivelog deletion policy based on your requirement. This example uses an sbt channel to back up datafiles 1 through4 and a datafile copy stored at /tmp/system01.dbf to tape:. Restore controlfile 9. This backup is an Rman intergrated backup and hours into the restore process it asks for tapes that belongs to a completely different backup session of the connecting to the rman catalog and the target database - change archivelog all crosscheck ; This will check the archivelog folder and then make the catalog agree with what is actually available. V khch hng: RMAN attaches an identifier called a tag to every backup it creates, as a way of identifying that backup that can be used with later RMAN commands.. A duplicate or copy database created by Recovery Manager, i.e., RMAN, is mostly used to test backup and recovery procedures before implementing them on the real database and eventually the RMAN backups are stored. For example: RMAN> CONNECT TARGET / RMAN> CONNECT CATALOG rman/rman@inst2 RMAN> BACKUP DATABASE ; Most RMAN commands take a number of parameters and must end with a semicolon. Mount database Continue reading RMAN Database A duplicate or copy database created by Recovery Manager, i.e., RMAN, is mostly used to test backup and recovery procedures before implementing them on the real database and eventually the RMAN backups are stored.
