IT05697: THE AGENT STATUS "UNREACHABLE" IS MISLEADING AND IMPLIES THAT THE AGENT IS NOT RUNNING

APAR status

  • Closed as program error.

Error description

  • Some WebSphere MQ File Transfer Edition commands may report an
    agent's status as "unreachable" when the agent status cannot be
    determined from the information currently available on the
    coordination queue manager. This is inaccurate, as these
    commands do not attempt to communicate with the agent, and so do
    not offer any indication of whether the agent is contactable.
    More information on common causes of this situation is available
    in the following technote:
    http://www-01.ibm.com/support/docview.wss?uid=swg21616381
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    The APAR affects all users of WebSphere MQ File Transfer Edition
    and all users of WebSphere MQ Managed File Transfer.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The WebSphere MQ Explorer FTE/MFT plug-in and the
    fteShowAgentDetails and fteListAgents commands used to report an
    agent's status as "unreachable" when the agent status could not
    be determined from the information held on the coordination
    queue manager.
    
    This was inaccurate, as these mechanisms did not attempt to
    communicate with the agent, and so were unable to determine if
    the agent could be contacted.
    

Problem conclusion

  • The product has has been changed to alter the UNREACHABLE state
    to UNKNOWN.
    The previously defined UNKNOWN status has been changed to
    UNDEFINED.
    
    UNKNOWN status now means that agent status updates were not
    received at the expected time intervals by the coordination
    queue manager. The agent might have stopped running due to an
    error, or have been shut down abruptly, or be running but
    experiencing communication problems. If an agent's status is
    shown as UNKNOWN, run the ftePingAgent command to determine if
    the agent can be contacted and is running.
    
    UNDEFINED status means that the agent's status cannot be
    determined. It might have published a status which is not
    recognised.

    an agent status can be shown as either UNREACHABLE or UNKNOWN,
