Hi,

We know that the standard IBM workload algorithm does load balancing of messages to an identical queue residing on multiple qmgrs i.e. route messages on a "round robin" basis between queue A on qmgr X and queue A on qmgr Y providing both qmgrs are available etc. etc. etc.

They also supply a sample cluster workload exit that introduces fail over i.e. route messages to queue B on qmgr X unless not available so route messages to queue B on qmgr Y.

Our problem is we need a workload exit to do both i.e. load balance a number of queues (A) on multiple qmgrs (X & Y) and then fail over a number of queues (B) on multiple qmgrs (X & Y).

We have been unable to find anything and our schedule is a bit tight to start developing a solution – any ideas?

Regards

If there is anyone out there who is curios about the solution -

On Windows NT take a look at support pack MC76 - it is ok for Windows and it can be recompiled for Linux with a few tweaks (have not tested it properly yet) - not sure about other platforms. That is if you are ok with a solution not supported by "IBM".

This does complicate the architecture though.
