Hi,
I have a problem as such:
QM1 has a queue with MAXMSGL at 10Mb
QM2 need to place messages onto this QM1 queue
QM1 and QM2 are both part of a big cluster.
.......
Now
QM2 has an automatic cluster sender channel to QM1. QM1 has a defined receiver channel TO.QM1 defined.
I have found that these channels are set to the default 4.1Mb in size in terms of what they can transmit, and of course, messages from QM2 to QM1 can't get there and so go to the dead letter queue.
How to solve this problem:
I can of course do one side easily...
On QM1 I run the command
ALTER CHANNEL(TO.QM1) CHLTYPE(CLUSRCVR) MAXMSGL(10000000)
But HOW?? do I get the automatic cluster sender to change also??
What do I do to QM2 to get it to 10MB???
The lower of the two sizes will win. So it will stay at 4.1Mb if I can't increase the QM2 automatic cluster sender?
Finally, why didn't the cluster sender automatically not be bigger than 4.1Mb since the queue managers were both set to be 10Mb. Weird.
Please help. |

Change the size of the SYSTEM.DEF.CLUSSDR.
The queue manager max size is not tied in anyway to any other object size. Nor are any other objects tied together so that changing the properties of one will change the properties of another.
It would be nice if there were a support pack or something that would allow you to change the size of *all* objects in one step. But this is also a simple matter of programming.

You only need to change it on the CLUSRCVRs. Since the Automatic Cluster Senders get their attributes from the receiving side's CLUSRCVR, that is all you have to change.
The next time the Automatic Cluster Senders restart, they will pick up the change you made in the CLUSRCVR on the receiving side, and at that time the automatic CLUSSNDRs will be at 10 MEG.
