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

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

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

Configuring RMAN channels

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:

Logging in to the Oracle Enterprise Manager

The following procedure provides instructions for starting the dbconsole and the Oracle Enterprise Manager interface. 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=SIDemctl start dbconsole

• On a Linux system, open a command shell and type the following commands:

export ORACLE_SID=SIDemctl start dbconsole

Output similar to the following output appears:

Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0Copyright (c) 1996, 2009 Oracle Corporation. All rights reserved.https://oracleoem.bgl.avamar.emc:5500/em/console/aboutApplicationStarting Oracle Enterprise Manager 11g Database Control ........ started.------------------------------------------------------------------Logs are generated in directory /home/oracle/app/oracle/product/11.2.0/dbhome_1/oracleoem.bgl.avamar.emc_spldb/sysman/log[oracle@oracleoem ~]$

The emctl start dbconsole command starts the dbconsole process for the database that is identified by the SID (system ID). The output for the emctl start dbconsole command contains a port number. In the example output, the port number is 5500.



2. To start the Oracle Enterprise Manager, open a web browser and type the following URL:

• From the Oracle host, type the following command:

https://localhost:port_number/em

• From a system other than the Oracle host, type the following command:

https://host_name: port_number/EM

where:

– port_number is the port number that the output from the emctl start dbconsole command shows.

– host_name is the hostname of the computer.

The Login screen appears.

3. Type sys in the User Name field.

4. Type the password for the sys user in the Password field.

5. Select SYSDBA from the Connect As list, and then click Login.

The disclaimer message appears in the Oracle Enterprise Manager.

6. Click OK.

The Home page appears.

The Schedule Customized Backup: Schedule page appears.

7. Select a schedule for the backup, and then click Next.

• To perform an on-demand backup one time only, select One Time (Immediately).

• To schedule a backup, select One Time (Later).

This option displays the Time Zone, Start Date, and Start Time options. Set these options appropriately.

• To schedule a backup to repeat, select Repeating.

This option displays the following options: Frequency Type, Repeat Every, Time Zone, Start Date, Start Time, and Repeat Until. Set these options appropriately.
