Error description

  • Customer complained the status of cluster sender
    channel(auto-defined) issuing by "dis clusqmgr" is incorrect and
    inconsistent with that issuing by "dis chs" on z/OS if cluster
    receiver channel is defined with multiple connection names on
    other side.
    If cluster receiver channel is defined with single connection
    name, the status of "dis clusqmgr" on z/OS is expected and is
    consistent with that of by issuing "dis chs".
    
    IBM change team recreated issue that the problem occurs as
    rriUPDATE_CACHE_CHL_STATE does not update the state of the
    channel when rriSO_RETRYABLE_SESSION is set (i.e. multiple
    addresses in the CONNAME).
    
    Note: the problem does not occur if the last connection-name in
    the separated list is used to connect to the partner.

    ****************************************************************
    The command DISPLAY CLUSQMGR(*) should show an STATUS that
    matches the STATUS of the CLUSSDR channel to each queue manager.
    In the case that the channel has multiple connection names or
    addresses the update of the cluster queue manager status is
    skipped when the channel status changes.
    

Problem conclusion

  • Function rriSendData (CSQXRMTR) now updates the cluster queue
    status when the CLUSSDR channel status has changed.
