    ****************************************************************
    * RECOMMENDATION: After applying the PTF that resolves this    *
    *                 APAR, all CMASes must be restarted.  Note    *
    *                 that the restarts do not need to occur at    *
    *                 the same time.                               *
    ****************************************************************
    When an EUI, API or WUI request specifies a BAS logical scope,
    method EYU0XLSI (XLSI) calls method EYU0TMLE (TMLE) to build the
    namelist that would be required to retrieve the specified data
    for the scope.  TMLE calls method EYU0BMLE (BMLE) to build a
    queue which contains one element for each MAS and resource
    associated with the logical scope.  To do this, BMLE must build
    a list that contains the name of each local MAS that is part of
    the logical scope.  BMLE builds this list in its working
    storage, and limits the list size to 199 MASes.  If more than
    199 MASes exist, then BMLE getmains a secondary area.  A logic
    error in BMLE causes the secondary area to be corrupted.  In
    most situations, this will result in a S0C4 abend in BMLE as it
    attempts to add additional elements to the list.
    
    When the abend occurs, or when any other error causes a failure
    in BMLE, TMLE is returned a failure indication.  TMLE will issue
    an exception trace and propagate the failure back to XLSI.  XLSI
    will also issue an exception trace, but it does not return a
    failure indication to its caller.  As a result, the requestor
    does not know that a failure occurred, and may re-execute the
    request, resulting in additional failures.
    

Problem conclusion

  • BMLE has been updated to correct the logic errors that cause it
    to corrupt secondary MAS lists.  Additional errors in the
    handling of these lists have also been resolved.
    
    XLSI has been updated so that if it receives a failure
    indication from TMLE, it will set a non-OK status.  The
    requestor will receive the following:
    
    -  EUI requestors will receive:
    
         EYUEI0650E Method <csfm> may not be invoked under logical
                    scope <scope>
    
    -  API requestors will receive:
    
    
         RESPONSE = 1028 (INVALIDPARM)
         REASON   = 1294 (SCOPE)
    
    
    -  WUI requestors will receive:
    
         EYUVC1283W  The specified Scope (<scope>) is not available
                     for this Context (<cicsplex>).
