2 Revision history Revision history The following table presents the revision history of this document. Revision Date Description 01 April 10, 2014 Initial release. Purpose The purpose of this technical note is to provide high-level details about how the Oracle Enterprise Manager integrates with the Avamar Plug-in for Oracle to provide backups, restores, and management of Oracle database servers. This technical note explains how to use features from the Oracle Enterprise Manager Database Control to back up Oracle database servers to an Avamar server, restore backups from the Avamar server, and perform other management tasks such as cross-checking a database, deleting backups, changing a backup to unavailable, and validating a backup. Audience Related documentation This technical note is intended for use by solution architects, administrators, and support staff who plan and deploy the Avamar Plug-in for Oracle. Such personnel should be familiar with Avamar architecture as well as backup and restore practices. The following EMC publications provide additional information: EMC Avamar for Oracle User Guide EMC Avamar Administration Guide EMC Avamar Release Notes Overview Oracle Enterprise Manager Database Control is a web-based interface that enables you to perform administrative tasks for Oracle databases. The Avamar Plug-in for Oracle integrates with the Oracle Enterprise Manager Database Control interface to enable you to back up and restore Oracle databases, crosscheck database backups, delete expired backups, schedule database backups, and other activities. The Oracle website and the Oracle Enterprise Manager Database Control online help provides more information about these features. 2 EMC Avamar Plug-in for Oracle Backup and Restore Management with Oracle Enterprise Manager Technical Note

3 Managing backups and restores with Oracle Enterprise Manager The Oracle Enterprise Manager Database Control interface provides many features, which enable you to back up, restore, and manage Oracle databases. The instructions in this technical note focus, in particular, on the options in the Manage section of the Availability tab. The functions in the Manage section include: Schedule Backup Manager current Backups Backup Reports Manage Restore Point Perform Recovery View and Manage Transactions Configuring RMAN channels Before you can use the Oracle Enterprise Manager Database Control to manage Avamar Plug-in for Oracle backups and restores, you must configure automatic channels from RMAN. Configuring RMAN channels on page 3 provides instructions. You also need a user account with SYSDBA privileges to log in to the Oracle Enterprise Manager. Typically, you can use the sys user. Or, you can create a user with SYSDBA privileges by typing the following commands from the SQL*Plus prompt: SQL> create user backupuser identified by backuppasswd; SQL> grant sysdba to backupuser Use the RMAN configure command to configure RMAN automatic channels for database backups and restores you perform with the Oracle Enterprise Manager. Use the --nocache option when you configure automatic channels. The --nocache option disables the Avamar client-side cache during backup and restore operations. Backups that you store on a Data Domain system must use the --nocache option. The following output shows the configuration requirements that the environment must meet before you perform backups and restores with the Oracle Enterprise Manager: RMAN> show all; RMAN configuration parameters for database with db_unique_name SPLDB are: CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default CONFIGURE BACKUP OPTIMIZATION OFF; # default CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default CONFIGURE CONTROLFILE AUTOBACKUP ON; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE 'SBT_TAPE' TO 'CONTROLFILE.spldb.%F'; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default CONFIGURE DEVICE TYPE SBT_TAPE PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE SBT_TAPE TO 1; # default EMC Avamar Plug-in for Oracle Backup and Restore Management with Oracle Enterprise Manager Technical Note 3

The following procedure uses the sys user to log in to the Oracle Enterprise Manager. You can use any user account that has SYSDBA privileges. For a RAC database, the dbconsole service can run from any RAC node. Before you begin, ensure that the Oracle listener is running. 1. Start the dbconsole: On a Windows system, open the Command Prompt and type the following commands: set ORACLE_SID=SID emctl start dbconsole On a Linux system, open a command shell and type the following commands: export ORACLE_SID=SID emctl start dbconsole Output similar to the following output appears: Oracle Enterprise Manager 11g Database Control Release Copyright (c) 1996, 2009 Oracle Corporation.

The output for the emctl start dbconsole command contains a port number. In the example output, the port number is EMC Avamar Plug-in for Oracle Backup and Restore Management with Oracle Enterprise Manager Technical Note
