    MQ listener fails to start although the MQ queue manager can
    start.
    
    This problem is a result of changes in HP Non Stop Server
    SPRs T9050J01-AWT and T9050H02-AWS, which were included in
    J06.14/H06.25 respectively.

Local fix

  • LOCAL FIX
    
    Set the environment variable "AMQ_NO_LISTENER_CHK=1" for OSS
    command line listeners.  For listeners running in PATHWAY, set
    an ENV value of AMQ_NO_LISTENER_CHK=1 in the listener
    serverclass.
    

Problem summary

  • Due to change in layout of OSS PIDS in T9050 J01 AWT and
    T9050 H02 AWS, information returned from PROCESS_GETINFOLIST_ is
    incorrectly handled by remote library code used by
    the listener. These SPRs were part of the H06.25 and J06.14
    RVUs, but can also be installed on H06.24 and J06.13.
    

Problem conclusion

  • Remote code changed to no longer expect OSS PID > 65537, but
    instead to specifically search only for OSS processes in
    PROCESS_GETINFOLIST_ call
    

Temporary fix

  • For listeners, define the following environment variable.
    AMQ_NO_LISTENER_CHK=1. For command line listeners, this should
    be exported in the environment, for PATHWAY listeners, this
    value should be set for the serverclass. If the problem is
    encountered with endmqlsr, the listener can be terminated
    using kill -9.  Note that PATHWAY listeners are terminated whe n
    the serverclass is stopped, or the queue manager is ended.
