Use this task to avoid problems that can occur when a messaging engine that
is configured to use DB2 v8.2 with the High Availability Data Recovery (HADR)
feature for its data store terminates
if the DB2 database fails over.
If you use the High Availability Data Recovery (HADR) feature
of DB2, note the following restrictions:
- The messaging engine default
messaging provider supports only the synchronous and near-synchronoous synchronization
modes of HADR. The default messaging provider does not support asynchronous
HADR configurations.
- The TAKEOVER BY FORCE command is permitted only when the standby database
is in peer state, or in a non-peer state (such as disconnected state) having
changed from peer state.
