Manually Discovering Instances

Manually discover all existing Oracle databases that will be backed up and restored. This one-time operation creates corresponding CommCell instances for each discovered database.

The SnapProtect software only discovers instances defined in the Oracle oratab file, which is created by Oracle at installation and acts as a database registry file. On Solaris systems, this file is normally located in the /var/opt/oracle directory and on Linux/UNIX systems, it is located in the /etc directory.

About This Task

By default, when you discover or create an Oracle instance, the SnapProtect software automatically creates an archive log subclient. You can disable this feature by setting an additional setting. For more information, see Disabling Automatic Archive Log Subclient Creation.

You can configure a data and log storage policy that is automatically assigned to all discovered instances. For information, see Configuring the Storage Policies for Discovered Oracle Instances.

When you add or discover an Oracle instance, the software sets the default block size to 1MB. You can change the Oracle block size. For more information, see Configuring the Oracle Block Size.
