Windows: Task manager interpretation

From Version 7.1, the interpretation of the processes that are listed by the Windows Task Manager has changed. The results can show IBM® MQ processes running for multiple installations on a server. Before Version 7.1, the process list identified IBM MQ processes running on only a single installation of the product on a Windows server.

The implications of this change depend on how the results are qualified and interpreted, and how the list of processes is used. The change affects you, only if you start to run multiple installations on a single server. If you have incorporated the list of IBM MQ processes into administrative scripts or manual procedures, you must review the usage.

On 64-bit Windows platforms, IBM MQ 8.0 processes and processes for earlier releases of the product can be easily identified. As queue managers for releases before IBM MQ 8.0 are 32 bit, all queue manager processes for releases before Version 8.0 have '*32' associated with their process names. In Version 8.0, the queue manager is 64 bit, hence the queue manager processes in Windows Task manager do not have an associated '*32'.
