Manager-of-Managers Environment
Configuring a Centralized Media Management Database
Chapter 8 369
On the MoM, add one cell at a time to the CMMDB.
Prerequisites • Data Protector Cell Managers in all cells have to have the same
version of Data Protector installed and running.
• Check that there are no backup, restore, or media management
sessions running on any of the cells to be added to the multi-cell
environment.
How to Configure
the CMMDB
To configure the CMMDB in the MoM environment, two phases are
required:
• Configuration of the CMMDB on the MoM Manager. See “Configuring
the CMMDB on the MoM Manager” on page 369.
• Configuration of the CMMDB on the client cell. See “Configuring the
CMMDB on the Client Cell” on page 370.
NOTE Once you have configured the CMMDB and start using it, it is not
possible to split it back into local MMDBs. It is not recommended to
recover the old state of a MMDB. Instead, you should create a new
MMDB from scratch.
Configuring the CMMDB on the MoM Manager
Log on to the MoM Manager and perform the following steps:
1. Copy the following directory to a temporary location for safety
reasons:
• On Windows: <Data_Protector_home>\db40\datafiles\mmdb
• On UNIX: /var/opt/omni/db40/datafiles/mmdb
2. Run the following command to merge the local MMDB into the
CMMDB:
• On Windows: <Data_Protector_home>\bin\omnidbutil
-mergemmdb <Cell_Server_Hostname>
• On UNIX: /opt/omni/sbin/omnidbutil -mergemmdb
<Cell_Server_Hostname>
