A level 0 incremental backup performs the same function as a full backup in that they both back up all blocks that have ever been used. Incremental backups are classified by level. An incremental backup at level 0 is identical in content to a full backup, but unlike a full backup the level 0 backup is considered a part of the incremental backup strategy.Īn incremental backup is a RMAN backup in which only modified blocks are backed up. A level 0 incremental backup is an RMAN incremental backup that backs up all data blocks in the data files being backed up. The following example uses a RUN command to make a level 0 incremental backup and allocates four channels to increase the backup speed. Connect with SYSBACKUP privileges to enforce the separation of duty security model.īack up the data files to the Oracle ASM disk group. Optionally, connect to a recovery catalog. In a new terminal window, start RMAN session and connect as TARGET to the database to be migrated. The following example uses an operating system utility to copy the server parameter file: SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL Ĭopy the server parameter file or initialization parameter file to a temporary location.

If the database is a physical standby database, and if managed recovery is started, then stop managed recovery.Ī physical standby database is a copy of a production database that you can use for disaster protection.įor example, connect SQL*Plus to the database with SYSBACKUP privileges (rather than SYSDBA privileges) to enforce the separation of duty security model, and run the following statement to stop managed recovery: Read-only transportable tablespaces cannot be migrated because RMAN cannot back them up. If the COMPATIBLE initialization parameter setting for the database is less than 11.0.0, then make any read-only transportable tablespaces read/write. To prepare the database for Oracle ASM migration: The database to be migrated to Oracle ASM storage is named mydb. You want to migrate the database to two Oracle ASM disk groups: +DATA for the database and +FRA for the fast recovery area.

This section makes the following assumptions: This section explains how to prepare the database for migration.
