Re: Hopping messages across clusters
Randy, If you want to do this programmatically, all I could suggest is that you try a channel exit. I wrote one a while back that checked that the remote QM was available before sending the message, and diverting the message to another QM if it wasnt. This worked fine on NT, but when I tried it on Linux, on checking the transmission queue depth I always got 0!!, whereas on NT 0 as expected. It is still on the back burner awaiting re-ignition...This approach does require channel defs etc...so may not be what you want. regards Peter Crowder, Randall [EMAIL PROTECTED] LCITY.COM To: MQSERIES Sent by: MQSeries List [EMAIL PROTECTED] cc: Subject: Hopping messages across clusters 24-Feb-2003 20:56 Please respond to MQSeries List [EMAIL PROTECTED] Intercommunication Gurus!!!

Re: Hopping messages across clusters
Peter, Thanks... That's an interesting suggestion. Likewise, thanks to all who have helped. I'm coming to the conclusion that there is no out of the box way to do it without creating some object definitions or coding something like an exit (or queue reader/writer on QM3).

Re: Hopping messages across clusters
Neil, issue MQPUT(1) on QM8 or QM9 with the OD.QMgrName=MQ3 and OD.ObjectName=QC.LOCAL Unfortunately, this results in the message going to the dead letter queue on QM3. Good point about the replies.

AW: Hopping messages across clusters
Randall, QM9 does not know about QC.LOCAL on QM1/QM2 because of the different cluster, so you can not put to QC.LOCAL. Using a remotequeue on QM9 (RNAME QC.LOCAL RQMGR QM1 for example) does not work because QM9 does not know about QM1 (different cluster) There is no way for QM9 to put to QC.LOCAL without additional definitions that are provided in cluster B (queues, qmgr alias, ) or defined in QM9 directly to make QM9 know the queue or the target queuemanager. Either make QM9 a member of cluster A, or use QM3 as a gateway to Cluster A. Regards, Stefan -Ursprüngliche Nachricht- Von: Crowder, Randall [mailto:[EMAIL PROTECTED] Gesendet: Montag, 24.
