Avoiding failover problems when you use DB2 v8.2 with HADR as your data store

Use this task to avoid problems that can occur when a messaging engine that is configured to use DB2 v8.2 with HADR for its data store terminates if the DB2 database fails over.

Why and when to perform this task

If you configure a messaging engine to use DB2 v8.2 with HADR for its data store and a DB2 failover occurs, the application server on which the messaging engine is running might stop. The cause of this problem is that the messaging engine does not treat the DB2 failover as a transient communications error.

When you configure a messaging engine to use DB2 v8.2 with HADR for its data store ensure that the messaging engine can restart automatically following an application server failure. Choose the option that is appropriate for your configuration:
