Error description
You are running OS/390 R10 or z/OS R1 in MVS COMPATIBILITY mode with CPSM R2.2. You have an LMAS that tries to CONNECT to the CMAS in this mode, but the LEEI transaction failed with ABENDASRA in CLET. The problem occurs in the ICT_COMPAT routine routine, +X'BB6' in EYU0CLET (UQ91544) because theDE_ASCB field WRK_NODE_ASCB field in CLET's stack has not been initialized. This bit of code was added by PQ78225 to insure that the CMAS is running at a higher dispatching priority than the LMAS that is in the process of connecting. This check is made ONLY if the LPAR is running COMPATIBILITY MODE. COMPAT mode is not supported at z/OS 1.3 or higher.

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V3R1M0 Users. * **************************************************************** * PROBLEM DESCRIPTION: An ABEND ASRA may occur at offset * * X'0D4C' in EYU0CLET if the MVS image * * is running in WLM compatibility * * mode. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all CMASes must be recycled to pick * * up the new code. Note that the restarts * * do not need to be done at the same time. * **************************************************************** Method EYU0CLET (CLET - ESSS Initial Contact) is called in the CMAS to process ATTACH and DETACH requests from a MAS. If the MVS image is running in WLM compatibility mode (only available on pre z/OS 1.3 systems), then CLET will attempt to compare the dispatching priority of the CMAS to that of the MAS in order to determine whether message EYUCL0024W should be issued. A logic error in CLET causes the reported abend because the ASCB address of the MAS is not being correctly loaded.
Problem conclusion
CLET has been changed to load the ASCB address of the ATTACHing MAS correctly.

Comments
An ABEND ASRA may occur at offset 0BBC in EYU0CLET if the MVS image is running in WLM compatibility mode. Method EYU0CLET (CLET - ESSS Initial Contact) is called in the CMAS to process ATTACH and DETACH requests from a MAS. If the MVS image is running in WLM compatibility mode (only available on pre z/OS 1.3 systems), then CLET will attempt to compare the dispatching priority of the CMAS to that of the MAS in order to determine whether message EYUCL0024W should be issued. A logic error in CLET causes the reported abend because the ASCB address of the MAS is not being correctly loaded. CLET has been changed to load the ASCB address of the ATTACHing MAS correctly.
