Chapter 18
Choosing the Cell Manager System
The Cell Manager is the main system in the Application Recovery
Manager cell. The Cell Manager does the following:
• Manages the cell from one central point.
• Contains the IDB (files with information about backup and restore
sessions).
• Runs the core Application Recovery Manager software.
• Runs the Session Manager that starts and stops backup and restore
sessions and writes session information to the IDB.
Therefore, before deciding on which system in your environment to
install the Cell Manager, be aware of the following:
✓ Supported platforms
See the http://www.hp.com/support/manuals
for details of the
supported versions/releases of these platforms.
✓ Reliability of the Cell Manager system
Since the Cell Manager contains the IDB and since backup and
restore cannot be performed if the Cell Manager is down, it is
important to choose a very reliable system in your environment for
the installation.
✓ Database required disk space
The Cell Manager holds the Application Recovery Manager Internal
Database (IDB). the IDB contains information regarding the backed
up data and session messages.
NOTE You do not have to use the Cell Manager as the graphical user interface
system.
