Error description
While in the process of upgrading to CPSM 6,1, the CMAS has been upgraded to 6.1. The MASes were upgraded to CPSM 6.1 while running CICS 5.6. Now during start up the EYUCS0207W and EYUCS0208I messages began to appear in the log for some of the MAS regions: EYUCS0207W applid Connected MAS CICSMAS is not responding - APPLID(CICSMAS) CICSplex(CICSPLX). EYUCS0208I applid Connected MAS CICSMAS is now responding - APPLID(CICSMAS) CICSplex(CICSPLX). The MAS CICSMAS was deemed non-responsive shortly after the TOP Connect was completed to the CMAS. From a CICS perspective the region was not hung or looping. The MAS did receive the MOS NQCR MAL from the CMAS. But when it tried to tried to return the MAL to the CMAS it failed with these exceptions: Task Mtd Prev Tran Obj Level Pt-ID Debug UOW CMAS/Usr Envr Local TOD GMT Clock Date 139 CAMR XLOP COIR COM Excp 1 CAMRXCP CPSM CICTRTA1 LMAS 09:55:18.61702 14:55:18.61702 2/07/24 139 XLOP .... COIR KNL Excp 2 CAMRFail CPSM CICTRTA1 LMAS 09:55:18.61702 14:55:18.61702 2/07/24 The MAL failed to be returned to the CMAS with its response. This failure in CAMR is what caused the CMAS to think the MAS was unresponsive. This failure occurred running the COIR task which is the RTA EVALDEF task.
Local fix
This issue only occurs when the RTA configuration has the separate task indicator (SEPTASK) set to YES on the evaluation definition (EVALDEF). Setting this to NO should bypass the issue, though it will change the behavior of the evaluation, with it running on the MAS LRT (long running task) rather than running on a separate task which is started for the evaluation.
Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM Users. * **************************************************************** * PROBLEM DESCRIPTION: A CMAS may report a MAS region as * * unresponsive with message EYUCS0207W or * * the MAS region may abend ASRA in CAMR. * * when a MAS resource monitoring (MRM) * * evaluation definition is defined for a * * CICSRGN resource. * **************************************************************** * RECOMMENDATION: Apply PTFs to all CMAS and MAS regions. * * This may be performed in any order. * **************************************************************** Real-time analysis (RTA) MRM evaluation definitions can be configured to monitor the CICSRGN resources. The requests to inquire these resources are sent to the appropriate MAS regions. The inquire for this resource is handled by EYU0NQCR. However logic to convert time values for the resource may overlay working storage. As a result, if the evaluation definition has the separate task indicator set, the field, KOPB_OACB_MPFX, required to reply to the request may be overlaid. With the incorrect value in KOPB_OACB_MPFX, the function to reply to the CMAS, CAMR may fail. The CAMR call may fail with reason METHOD_FAILED, or a 0C4 abend occurs in CAMR, which results in the MAS abending ASRA in CAMR (ASRA with SCODE=S00C4 TRAN=COIR). The failure in CAMR prevents the CMAS receiving the required response, resulting in the CMAS reporting the MAS as unresponsive with the following message: EYUCS0207W applid Connected MAS CICSMAS is not responding - APPLID(CICSMAS) CICSplex(CICSPLX).
Problem conclusion
The convert time logic in EYU0NQCR has been corrected to address the overlay, to allow CAMR to respond correctly.
