9.2.6 Restarting Novell Zenworks Server Services After
Restarting the Database
After restarting the PostgresSQL database on the ZENworks Linux Management Server, the
database connections will be restored in approximately 15 minutes. During this time, the ZENworks
Control Center and zlman utility might display database-connection errors.
To restore the connections immediately, restart the novell zenworks services by running the
following command:
/opt/novell/zenworks/bin/zlm-config --restart

9.3.1 Backup and Recovery Solutions

Oracle provides two methods of backup and recovery:
Recovery Manager (RMAN)
User-managed backup and recovery
The RMAN utility is automatically installed with the database. It can back up an Oracle8 database
and all later versions of an Oracle* database. RMAN uses server sessions on the database to perform
backup and recovery. RMAN has its own syntax and is accessible either through a command-line
interface or through the Oracle Enterprise Manager GUI. RMAN also provides APIs to interface
with third-party media managers.
The advantage of RMAN is that it obtains and stores metadata about its operations in the control file
of the database. An independent recovery catalog can be set up, which is a schema that contains
metadata imported from the control file, in a separate recovery catalog database. RMAN performs
the necessary record keeping for backups, archived logs, and so forth using the metadata, so
restoration and recovery is greatly simplified.
An alternative method of performing recovery is to use operating system commands for backups and
SQL*Plus for recovery. This method is called User-managed backup and recovery.
