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.
About this task
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 when the standby database had last changed from peer
state to its current state (such as disconnected state).
