Hi,
How to set up Message Exit on MQ Clustering? e.g. QMA is Full repos and QMB is partial repos and I only wanna set up Message exit on the Cluster sender and receiver in QMA.
I tried setting up on QMA cluster receiver, it cant connect as it request for QMB cluster sender to have the exit too.
And i tried setting up on QMA cluster Sender, it is not updated on the Cluster Receiver of QMB.
What shld I do?
Thanks |

Did you try setting it on the cluster receiver instead of the cluster sender as the cluster receiver is used as a template to create the cluster sender??

a cluster receiver channel is distributed within the cluster, used to create the implicit defined cluster sender on other queuemanagers. if you define an exit in the cluster receiver channel, then the exit is also needed on the other queuemanagers, or you have to use a channel autodefinition exit to wipe out the exit field on these queuemanagers.
an explicit defined cluster sender is not distributed within the cluster, so an exit here will not harm you, but please be aware that the implicit cluster sender channels are used if they are created, not the explicit ones.

Hi,
fjb_saper: I cant set at the cluster receiver on QMB because it is not under my administration.
Mr Butcher: Is it we must use channel autodefinition exit for this?? no other way?
Thanks |

If you want to set any form of exit on a cluster channel, you are constrained by the way clustering works, most of the time any cluster sender the QM is using is based on the definition of the cluster receiver at the other end of the channel.
This means that if you have for example z/OS at the R end of the channel and Unix at the S end, then the Unix clussdr channel will use the exit specifications coded on the definition of the clusrcvr on z/OS (except for initially joining the cluster or refresh repos(yes)).
This won't work too well! On z/OS you just code the name of a load library member like for example MSGEXIT('MSGEXIT'). While Unix expects something like MSGEXIT('/var/mqm/exits64/exitlib(msgexit)').
Ooops
The only way round this is to code a channel autodefinition exit.

Yes. Been there, had to do that.
