Error description
Under certain conditions if a cluster sender channel process terminates unexpectedly, the cluster repository manager cache may not get informed of the state change. If the channel status table and cluster cache information remain out of sync, it may lead to incorrect product behaviour based on the repository manager believing that the channel is running.

N/A
Problem summary
**************************************************************** USERS AFFECTED: Customers using clustering that encounter an unexpected channel process termination are potentially affected. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: The repository manager maintains a cache of channel status information for cluster channels, the cache is normally updated when the channel status table is updated. Under certain circumstances, following an unexpected channel termination, the cached copy of this data may become out of sync with the status table. The stale cache data may lead to incorrect product behaviour in cluster related operations.
Problem conclusion
The logic was corrected to ensure that the cluster cache would be updated in step with the channel status table after handling abnormal termination of a channel MCA. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.13 v9.0 LTS 9.0.0.8 v9.1 CD 9.1.3 v9.1 LTS 9.1.0.3 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 ---------------------------------------------------------------
