Error description

  • After recycling your CMASs and LMASs, Topology connect fails
    for one of your LMASs. You receive messages:
    EYUTS0002E Topology Connect for CICSXXX FAILED - APPLID(CICSXXX)
    CICSPLEX(plexname)
    
    EYUWM0403E  Workload Manager Task has reported an error
    processing event (SysGroup) for CICS Group ( CICSGRP ) .
    
    AFter you receive these messages, all attemps to connect the
    LMAS fail.

Local fix

  • Remove the LMAS from the CICS system group CICSGRP and re-add
    the LMAS to the CICSGRP. Restart the LMAS.

    * RECOMMENDATION: After applying the PTF that resolves this    *
    *                 APAR, all CMASes must be recycled to pick    *
    *                 up the new code.  Note that the restarts     *

    ****************************************************************
       When Topology Connect fails, module EYU0TSSE (TSSE - Topology
    Complete MAS Termination) is called from EYU0TSSC (TSSC - Top-
    ology Connect) to clean up resource allocated during the connect
    process.  If an exception occurs in TSSE or a method called by
    TSSE, the CICS System Descriptor Block (CSDB) for the MAS may be
    left in an inconsistent state.  If the MAS agent is restarted,
    Topology Connect will continue to fail because the CSDB indi-
    cates that the MAS is already connecting.
       The initial exception which caused Topology Connect to fail
    was a response and reason of INVALID / INVALID_LIST_ATTRIBUTES
    returned to EYU0TSRC (TSRC - Topology Refresh CSDB) by EYU0XCLK
    (XCLK - Cache Compare Search Lists).
    

Problem conclusion

  •    Module EYU0TSSE was modified to tolerate exceptions returned
    from methods called to clean up resources on behalf of the MAS
    whose connection is terminating.  This will allow the MAS agent
    to be restarted via the COLM transaction, once the MAS initial-
    ization timeout limit (MASINITTIME) has passed.
       Code was added to TSRC to produce an SDUMP containing the
    CMAS and ESSS address spaces and the TOP and Cache data spaces
    to facilitate diagnosis of the exception in XCLK.
       EYU0TSGR (TSGR - TOP System Group Remove) was modified to fix
    a problem which could result in attempts to generate notifi-
    cations for a null scope, resulting in message
    .
       EYUTS0013E  CICS System          Not Found
    .
    with a null system name.  TSGR was also updated to prevent
    incorrect deletion of a cache list allocated by another method.
