Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex/SM V3R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: Abend ASRA/S0C4 may occur in a CMAS in * * method EYU0BMLE (BMLE) when an EUI, API * * or WUI request specifies a BAS logical * * scope. * * * * The error is more likely to occur when * * the scope represents 200 or more MASes. * * * * In addition, the requestor will not * * receive an indication that an error has * * occurred. * **************************************************************** * 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>).
