Backup with OEM   «Prev 

Run RMAN from Enterprise Manager

Starting RMAN from the OEM

  1. Connect to the OEM console by using sysman as the Administrator, oem_temp as the Password, and localhost as the Management Server. Approve the entries by clicking OK.
  2. Next, you would double-click Databases, and right-click the pets database. We have done that for you here. This displays the option for Backup Management. Click Backup to engage the Backup wizard.
  3. The Backup Wizard is engaged, and the Introduction screen appears. This is the end of the simulation. Click Exit.

Recovery Manager (RMAN) is an Oracle Database client that performs backup and recovery tasks on your databases and automates administration of your backup strategies. It greatly simplifies backing up, restoring, and recovering database files.
The RMAN environment consists of the utilities and databases that play a role in backing up your data. At a minimum, the environment for RMAN must include the following components:
  1. A target database: An Oracle database to which RMAN is connected with the TARGET keyword. A target database is a database on which RMAN is performing backup and recovery operations. RMAN always maintains metadata about its operations on a database in the control file of the database. The RMAN metadata is known as the RMAN repository.
  2. RMAN client: An Oracle Database executable that interprets commands, directs server sessions to execute those commands, and records its activity in the target database control file. The RMAN executable is automatically installed with the database and is typically located in the same directory as the other database executables. For example, the RMAN client on Linux is located in $ORACLE_HOME/bin.
Some environments use the following optional components:
  1. flash recovery area: A disk location in which the database can store and manage files related to backup and recovery. You set the flash recovery area location and size with the DB_RECOVERY_FILE_DEST and DB_RECOVERY_FILE_DEST_SIZE initialization parameters.
  2. media manager: An application required for RMAN to interface with sequential media devices such as tape libraries. A media manager controls these devices during backup and recovery, managing the loading, labeling, and unloading of media. Media management devices are sometimes called SBT (system backup to tape) devices.
  3. recovery catalog: A separate database schema used to record RMAN activity against one or more target databases. A recovery catalog preserves RMAN repository metadata if the control file is lost, making it much easier to restore and recover following the loss of the control file. The database may overwrite older records in the control file, but RMAN maintains records forever in the catalog unless deleted by the user.
