Error description
If two appliances are configured for disaster recovery and the replication link between them is broken then it is possible for a partitioned state to occur, whereby the data is out of step on the recovery appliance. The documented process to resolve a partitioned state is to run makedrsecondary on the appliance whose data should be discarded, then run makedrprimary on the appliance whose data should be kept. The queue manager data is then synchronized between the appliances to restore normal operation. In some partition scenarios it is sufficient to only run the makedrsecondary command. If the makedrprimary command is then run while data is being synchronized it incorrectly fails with message "AMQ6523: The command failed because synchronization is in progress."
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of the IBM MQ Appliance who have established appliances in a disaster recovery configuration. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: The makedrprimary command failed to distinguish between data being synchronized to the appliance and data being synchronized from the appliance when resolving a partitioned state.
Problem conclusion
The makedrprimary command has been updated to correctly check the status of synchronization. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.6 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
