Software versions : MQ 5.3, WAS 5
Three queue manager QM1, QM2 and QM3 are in a cluster. QM1 and QM2 have one local queue each with same name (say LQ). Both LQs are shared in the cluster so they are visible on QM3. App is on the same box as QM3. App connects to QM3 using JMS and tries to put messages on clus q LQ. Messages go to QM1 and QM2 in round robin. so far so good. Now I create an alias queue (ALQ) on QM3 (alias to clus q LQ) and app tries to connect to ALQ. Call fails and RC is 2082 (unable to resolve base Q name). Any idea, why? is this a known problem with JMS or MQ5.3? I know a few other projects in my company which faced the same problem but could not resolve it. |

Create local aliases on QM1 and QM2 to your queue, and then share the alias in the cluster, not the actual local queue.

Few pointers other than this from the manual.
"MQRC_UNKNOWN_ALIAS_BASE_Q
An MQOPEN or MQPUT1 call was issued specifying an alias queue as the target, but the BaseQName in the alias queue attributes is not recognized as a queue name.
This reason code can also occur when BaseQName is the name of a cluster queue that cannot be resolved successfully.
Corrective action: Correct the queue definitions.
"
-Did you spell the name of the cluster queue that is published to qm3, correctly.
-Are your clussdr channels up and running and can you see all the qmgrs in cluster if you issue dis clusqmgr(*)
-What type of app are you using to put messages to this queue. Is that app doing something funny in the od, like specifying a hardcoded qm name or queue name
Cheers

To Answer your question:
1. Did you spell the name ........
Yes, I checked the Alias queue defination
2. Are your clussdr channels up ..................
Yes, As I said ealier, if I use the cluster queue name directly instead of Alias queue name, messages flow successfully
3. What type of app are ..............
Well, App is not doing anything to OD and if it was, the opening of clus queue directly should have been impacted also. But as I said its working fine. |

Could you post the following defs here.
-QA def
-Clusterq Def
-Output of dis qcluster(*) on qm3.
-Output of dis clusqmgr(*)
-if you have and can, post the open/put code.
-What api call is throwing, is it mqopen.
-Did you try amqsput to put message to this alias queue. whats the result.
Well, assumptions should never be made and hence i asked the 3rd question. I know if you use the same app on both queues, then the question of OD does not arise. :)
Cheers
