MQSeries.net :: View topic - Sending messages through cluster channels to Non cluster Qs

Hi guys, Ive been searching the APARS of 7.5 fixes but no luck.

Here is the story:
We have 4 servers/queue managers running on 7.5.0.5
These are quadruplets with the same set of objects but a couple are active and a couple are passive. These existing objects are standard local queues and svrconn channels and have been used like this for years.

Last week we created new objects, cluster channels and clustered queues, and set 2 of the 4 QMGRS as Full repos.

The very next morning after the creation, we saw messages in the NON CLUSTERED passive queues , all teams involved in that flow investigated, including app teams and myself (MW team).

Considering the possibility i turned a NON CLUSTER into a CLUSTER queue, I throughly checked everything done the night before. It turns out , everything was done correctly , NON CLUSTER passive QUEUE sill has an ALTDATE from 2013.

We had ruled out MQ since cluster object creation was done properly, however, since I was pulled in directly to back out the CHG, i forgot to take any evidence of the current failing state

Since its an old version, we could not seek out IBM for assistance.

We reapplied the CHG last night and this morning we got exactly the same result, this time no other application had done any changes, checked CLUSTER XMITQs and CLUSTER CHANNELS (we set DEFCLXQ to CHANNEL) and their LGETTIME and LSTMSGTI stamps matched LPUTTIME in the NON CLUSTERES passive queues.

Once I deleted the cluster configuration, the flow remained in the original pair of QMGRS . instead of jumping into the other passive queue managers.

Has this happened to you guys? I cant find this specific situation in the APARS. The putting application is IBM's WAS

Any comment is appreciated, Thanks in advance
