Hot backup fails with Oracle not available error
The Avamar Plug-in for Oracle uses Oracle RMAN for a hot backup. Oracle RMAN requires the Oracle database to be running for a hot backup.
If the database is not running, a hot backup fails. Oracle RMAN then returns the following error:
Oracle not available
To start the Oracle database before a hot backup, use SQL*Plus:
- Connect to the Oracle database by typing the following command:
sqlplus "/as sysdba"
- Start the Oracle database by typing the following command:
startup;
The startup process displays status information about the Oracle instance.
ORACLE instance started.
