Using RMAN commands, you can easily perform database recovery from your RMAN backup sets. In this video, learn the steps required to restore your database from an RMAN backup, using the SET UNTIL clause to perform point-in-time recovery, the differences between RMAN RESTORE and RMAN RECOVER, and the purpose of the OPEN RESETLOGS command.
- There are four steps for using RMAN…to perform major recovery of an Oracle database.…These steps are:…One, place the database in the…appropriate state for recovery.…For example, we need to close the PDB…before we can recover it,…or put the Oracle instance in Mount Mode…in case we want to recover our entire CDB,…or container database.…This can be done as part of the RMAN recovery strip,…as we'll see later in our chapter.…Two, in order to perform incomplete recovery,…which means recover the database…up to a specific point in time,…we will use the Set Until command…to specify the time, SCN, system change number,…or log sequence number at which the recovery terminate.…
Three, restore the necessary database files…using the RMAN Restore command.…This command copies the database data files…from within the RMAN backup set…and into their appropriate location in our database.…Four, recover the data files using the Recover command.…This rolls the database forward,…after a Restore command by applying…the changes stored in our archived Redo Logs.…
