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 DESCRIPTION: An ABEND ASRA may occur at offset       *
    *                      X'0D4C' in EYU0CLET if the MVS image    *

    ****************************************************************
    * 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
