APAR status

  • Closed as program error.

Error description

  • A Subscription attempt fails when a temporary dynamic queue is
    specified for receiving publications. The trace for process
    amqfxba shows:
    
    Object Name   {+00C} | 'TEST49618C84022F0020
    15)----------------}  apiEnquireObject (rc=OK)
    Local queue exists. Now check it is a suitable dest.
    Queue is not suitable as a destination.

    lpiSPISubscribe Completion Code: MQCC_FAILED Reason: 2522
    Completion code:2, Reason code:3076 returned from Kernel
    
    3076 - MQRCCF_Q_NAME_ERROR
    
    Queue definition for model queue shows:
    DEFTYPE(TEMPDYN)
    
    This may happen when the Pub/Sub subscription application is
    written for WebSphere Message Broker prior to v7. It may
    fail to register the subscription when run against WMQ v7.
    

Local fix

  • Apply Fix or change doe to use Perm dynamic queue.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users migrating Pub/Sub applications that use RFH2 headers to
    register subscriptions.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    Pub/Sub applications written to the v7 WMQ APIs can be durable
    or non-durable. A durable subscription must receive
    publications on a queue that is guaranteed to be present until
    the subscription is deleted. As this was not required for RFH2
    applications by earlier broker implementations, the older
    behaviour must be emulated in appropriate situations.
    

Problem conclusion

  • The emulation provided for applications that use RFH2 messages
    to register subscriptions, is modified to allow them to
    continue using temporary dynamic queues. When the queue is
    closed the subscription is also de-registered and removed.
