Maintaining the HADB Database

This section explains how to maintain the HADB database within the Sun Cluster HA for Sun Java System Application Server EE (HADB) data service.

How to Maintain the HADB Database

When you want to run HADB maintenance commands that initiate a rolling restart of the HADB nodes, the HADB resource probe in the fault monitor must be disabled before the maintenance commands are executed and then enabled after the commands and the rolling restart have been completed.

1. Disable the fault monitor.

   # clresource unmonitor resource

2. Run the commands that might initiate a rolling restart.

   The hadbm subcommands that might result in a rolling restart include set, restart, and addnodes.

3. Reenable the fault monitor.

   # clresource monitor resource

Alternative Method of Maintaining the Database

Alternatively, the HADB resource can be disabled and HADB started outside Sun Cluster control while maintenance commands are being performed.
