Error description
ABEND0C4-11 IEAVEPST+x'1420' when modules EYU9NLDCNLDCissues a POST SVC (x'0A02')and when module EYU9NLIDNLIDissues a POST SVC .the POST SVC fails with a S202-0C. The ECB was EXEC CICS WAIT EVENT under the QR TCB. CPSM is executing under L8 TCB . Therefore a S0C4-10 occurs trying to get access a tran iso ECB that belongs to the task that was waited under the QRTCB . The WAITED task was a TRANACTION ISOLATED task. the CPSM task is running in a subspace and is not allowed to touch storage that belongs to other tasks.

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V3R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: If Transaction Isolation is active in a * * MAS and CICS programs are running on an * * Open Transaction Environment (OTE) TCB, * * then the following messages may be * * issued: * * * * DFHAP0701 <applid> An abend (code 202 * * /AKEB) has occurred in exit program * * EYU9NLID at exit point XRSINDI. * * * * DFHAP0701 <applid> An abend (code 202 * * /AKEB) has occurred in exit program * * EYU9NLDC at exit point XDUREQC. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all CMASes and MASes must be recycled * * to pick up the new code. Note that the * * restarts do not need to be done at the same * * time. * **************************************************************** The CICSPlex SM Global User Exits (GLUE) programs are defined with EXECKEY(CICS). As such they expect to receive control in the base space if Transaction Isolation is active. However CICS may not switch to base space when a GLUE is called. As the CICSPlex SM GLUEs typically issue the MVS POST macro against an ECB waited on by another CICS task, the CICS dispatcher POST exit routine (DFHDSPX) gets called in the subspace mode of the caller. As part of the DFHDSPX processing, an additional MVS POST may be issued to re-dispatch the CICS QR TCB. If this POST causes the MVS POST routine IEAVPST to gain control in subspace mode, then the abend 202 may occur as IEAVPST attempts to touch ECBs in another subspace.
Problem conclusion
Because CICS may not call EXECKEY(CICS) defined GLUEs in base space, the following CICSPlex SM GLUEs have been updated so that they will switch to base space if they need to perform any work: EYU9NLDC - XDUREQC EYU9NLDR - XDUREQ EYU9NLID - XRSINDI EYU9NLME - XMEOUT (MAS) EYU9NLSO - XSNOFF EYU9NMST - XSTOUT EYU9NMTE - XMNOUT EYU9XLGR - XPCTA EYU9XLME - XMEOUT (CMAS) EYU9XLSR - XSRAB CICS will switch back to the tasks subspace if necessary after the GLUE has completed processing. To allow the GLUEs to switch to base space, EYU9XLEV has been updated to copy the CICS Storage Manager Transaction Isolation token to the XLWA.
