Rman backup and recovery scenarios pdf
Database administrator workshop: Recovery Scenarios on 11gAll rights reserved. Post a Comment. Olden days, we use traditional backup putting tablespace in hot backup mode to backup the database. When we recover the database, we use traditional backup as a base and apply archive log files to recover the database. We have some issues when we dealt with traditional backup.
Rman Recovery Scenarios
However, some of the most common scenarios for database restore and recovery are presented in full here:. The procedures outlined here will restore the whole database or individual tablespaces to their original locations. You must have the complete set of archived logs and incremental backups needed for media recovery of your available datafile backups. For any datafiles for which you have no backup, you must have a complete set of online and archived redo logs going back to the creation of that datafile. With a complete set of redo logs, RMAN can re-create a datafile for which there is no backup, by creating an empty datafile and then re-applying all changes since the file was created as part of the recovery process. If automatic channels are configured, then RMAN allocates all channels configured for the available device types according to their parallelism settings. You must restore and recover the whole database.
