./AgentConfig

1. Configure database access
2. Configure Oracle instance information
3. Quit
Please enter your selection:

5. Type the user name that is in the beoper group on the Linux system. (- use the database owner name - in this case oracle, not the user created for the Backup Exec agent - vrtsralus. )

If the authentication fails when the Oracle resources are backed up, the backup job fails. If the authentication fails when you browse the backup sets for a restore job, then the backup sets become unavailable, and you must run a DBA-initiated restore job to restore data.

The logon credentials are not stored on this computer.

7. Type the full computer name or IP address for this computer.

You must use the same form of name resolution for all Oracle operations. For example, if you use the IP address of this computer for backup operations, you must also use the IP address for restore operations. If you use the full computer name for backup operations, you must also use the full computer name for restore operations.

8. When prompted, specify if you want to use a custom port to connect to the media server communications between this computer and the media server during Oracle operations.

Port 5633 is used by default. If you change the port number on this computer, you must also change it on the media server, and then restart the Backup Exec Job Engine Service on the media server. If a Windows firewall is enabled, you must add this port as an exception.

See Setting default backup network and security options.
