Info

We created an RMAN command file including the checkpoint SCN from this listing: T In this example: - set until scn = 264582 specifies a SCN for the subsequent restore and recovery commands. - restore controlfile causes RMAN to restore the controlfiles to all control file destinations. The control files are not restored by the restore database command. - restore database restores all datafiles belonging to the database. Existing datafiles are overwritten. - alter database open resetlogs is the only way to open the database again, because the data in the redo logs cannot be used any longer. - After a successful database point in time recovery, a backup of the database is required. 8.3.4 Duplicate database The RMAN duplicate command allows you to use your target database backups to create a test database while still retaining your original database. The command takes backup sets or image copies of your target database files and generates a new database. A duplicate database is especially useful if your production database must be up and running 24 hours per day, 7 days a week. 114 Backing Up Oracle using Tivoli Storage Management
As part of the duplication operation, RMAN manages the following: Restores the target datafiles into the duplicate database and performs incomplete recovery using all available archived redo logs and incremental backups. Opens the duplicate database with the RESETLOGS option after incomplete recovery to create the online redo logs. Generates a new, unique database identifier for the duplicate database. When duplicating a database, you can do the following: Skip read-only tablespaces with the skip readonly clause. Read-only tablespaces are included by default. If you omit them, you can add them later. Create your duplicate database in a new host. If the directory structure is the same on the new host, you can use the nofilenamecheck option and reuse the target datafile filenames for the duplicate datafiles. Use the set until option when creating the duplicate database to recover it to a non-current time. By default, the duplicate command creates the database using the most recent backups of the target database and then performs recovery to the most recent consistent point contained in the incremental backups and archived redo logs. Use the duplicate command without a recovery catalog. Register the duplicate database in the same recovery catalog as the target database. This option is possible because the duplicate database receives a new database identifier during duplication. If you copy the target database using operating system utilities, the database identifier of the copied database remains the same so you cannot register it in the same recovery catalog. In our test environment, we duplicated the database oslo to the database berlin. Both databases are located on the same AIX system. We performed the following steps: We created an Oracle password file for the new instance berlin: cd $ORACLE_HOME/dbs orapwd file=orapwberlin password=change_on_install entries=10 Chapter 8.
