Error description

  • By default it is assigned transaction ID 'BBOC' but the
    customer is allowed to change this to any transaction ID that
    they prefer to use. Since the BBOACNTL program doesn't know
    what that transaction ID is, it saves the transaction ID that
    was used when the WOLA Task Related User Exit (TRUE) is
    started. The failure happens when the CICS transaction ID which
    was saved when the TRUE was activated is a CPLT transaction
    fails. Yet CPLT is an internal CICS program and so we cannot
    modify the respective transactionID

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V9.0 for z/OS                        *
    ****************************************************************
    * PROBLEM DESCRIPTION: A transaction CPLT abend ASIB occurred  *
    *                      during transaction roll back.           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When the WOLA Task Related User Exit (TRUE) is enabled during
    CICS startup, the transaction ID is saved by bboacntl. Later on
    the saved transaction ID can be used for transaction recovery.
    When a transaction ID of CPLT is used during transaction
    recovery, the following message is issued:
    DFHAC2236 03/04/2020 09:47:37 AP06CC18 Transaction CPLT abend
    ASIB in program DFHSIPLT term ????. Updates to local
    recoverable resources will be backed out.
    

Problem conclusion

  • The WAS z/OS Optimized Adapters CICS PLT Init program,
    bboacplt, was changed to specify CTID=BBOC when starting the
    task related user exit (TRUE).
    
    The Optimized Adapters CICS Control transaction program,
    bboacntl, will use the CICS transaction identifier specified on
    CTID= when specified. If CTID= is not specified and the CICS
    transaction identifier is CPLT, BBOC will be used as the CICS
    transaction identifier instead of CPLT.
    
    The following shows how to specify a CICS transaction
    identifier BBOC when starting the WOLA TRUE.
    BBOC START_TRUE CTID=BBOC
    
    The fix for this APAR is targeted for inclusion in fix pack
    9.0.5.5 and fix pack 20.0.0.7 for WebSphere Application Server
    Liberty. For more information, see 'Recommended Updates for
