To ensure availability of the persistent state database, you can install a clustered database setup and enable cluster failover handling.

Concepts

Important services should not hang, if the persistent state database is not available. So, in case the persistent state database becomes inoperative in a clustered setup, it will automatically be replaced by a compensatory database of the cluster.

Steps:

1. Install Oracle cluster setup
   Before you can enable cluster failover handling, you need to install a clustered setup on your Oracle database.
2. Enable cluster failover handling
   Enable the failover handling as described below.

Enabling Cluster Failover Handling

You can enable cluster failover handling in the

xUML service composite of the persistent state service. It is governed by to tagged values:

Refer to Persistent State Components for more information on persistent state settings on the

composite.
