Error description
You are using CPSM Workload Management WLM to manage routing in your CICSPlex. Your workload is setup to use the GOAL or LNGOAL algorithm. Under the direction of IBM Service, you turn on WLM trace level 19. You then find an abend in CPSM method WNAL. In the job log for the routing region where this WLM Level 19 trace was turned on, you see messages similar to the following: . DFHDU0205 <applid> A SYSTEM DUMP FOR DUMPCODE: AP0001 , WAS SUPPRESSED BY THE XDUREQ USER EXIT EYUXL0900I Starting Environment Recovery EYUXL0905E <applid> ASRA IN WNAL, OFFSET 00000A3E PSW=07856000 98D12CCE EYUXL0905E INTC=0010 ILC=6 TXCP=7F1D2001 SCODE=S00C4 TRAN=ABCD TASK=0012345 EYUXL0905E Methods=WNAL,WASV,WDTR,XLOP . An SVC dump is produced. . . Additional Symptom(s) Search Keyword(s): KIXREVSVR
Local fix
Do not turn CPSM WLM Level 19 trace on when using GOAL or LNGOAL
Problem summary
**************************************************************** * USERS AFFECTED: * * All CICSPlex SM V5R3M0 users * **************************************************************** * PROBLEM DESCRIPTION: * * When using CPSM Workload Manager to control your dynamic * * routing environment, and are routing dynamic transactions * * using the GOAL or LNGOAL routing algorithms, and WLM Trace * * level 19 has been activated, then an ASRA abend is reported * * in module EYU0WNAL. * **************************************************************** * RECOMMENDATION: * * After applying the PTF that resolves this APAR, all MASes * * acting as WLM routing regions (TORs) must be recycled to * * pick up the new code. Note that regions do not need to be * * brought down and restarted at the same time. * **************************************************************** During execution of the dynamic routing algorithm processor (EYU0WNAL), details of the state of each target AOR are held in a chain of AOR work element blocks (WAOWs). These blocks are constructed in the WLM dataspace, and so require an Alet and an Offset to locate each WAOW element. During WAOW data collection, Access Register 15 (AR15) is used to locate the first WAOW for each new CEC/Sysplex. When addressability to that WAOW is no longer required, then General Register 15 (GR15) is cleared but but the Alet value in Access Register 15 is not. This residual value has no ill effects, until WLM trace level 19 is activated and the routing algothm being used is GOAL or LNGOAL. When that happens, an attempt to trace out the "GOAL System Group Class Block" (WSGC) results in an ASRA abend, because the value held in the Alet-to-offset table is located from the address in GR15, but the residual ALET value in AR15 causes a mis-location of the required conversion table entry.
Problem conclusion
When addressability to the first WAOW element is no longer required, then the ALET reference for the WAOR is cleared out of Access Register 15.
