Error description

  • The customer converted (Migrated) CICS TS 5.1 Region to
    CICS TS 5.3 and the MQ is Version 8. They are running Simple
    Checks and Validations to include CKQC transaction and they are
    receiving CSQ3201E thrown when this does not occur under CICS
    TS 5.1
    .
    CSQ1MSTR log shows:
    CSQ3201E ! ABNORMAL EOT IN PROGRESS FOR USER=
    CONNECTION-ID=CICSRU THREAD-XREF= JOBNAME=CICS ASID=0063.
    TCB=009C0490.
    .
    Both EBs have EBACTL on which shows back in application:
    Jobname CICS   Conntype CICS     ASID x0063  ASCE 0E90D450
    EB 0C948CD0 ACE 0C948C70 Thread 40404040 Tran      Task
    40404040
    TCB 009C0490 (EBACTL = ON)
    EB 0C9486B8 ACE 0C948658 Thread 00000000 Tran CKTI Task
    0000042C
    TCB 009C0490 (EBACTL = ON)
    .
    Formatting out SUMM REGS FORMAT JOBSUM does not contain TCB
    009C0490 in the MSTR address space. %MQURE does not contain any
    entries for the above EBs.
    .
    The Change Team reviewed the dump. They state what has happened
    is that the QR TCB has disconnected from the queue-manager
    before L8 TCB 009C0490 in asid x0063. When the QR TCB
    disconnects, it will set AGNTDEOT for the daughter AGNTs (of
    which L8 TCB 009C0490 is one). At CICS 530, before
    the QR TCB disconnects it will issue a QRPL_ENDCTX request
    which will result in a CSQCEOTE IRB being scheduled on any L8
    TCBs which are still connected to the queue-manager. If the
    CSQCEOTE IRB runs after the QR TCB has disconnected, then the
    CSQ3201E message will occur due to AGNTDEOT being set (this
    results in CSQPARHX issuing a SSOBFEOT boroadcast with SSETYPE
    set, indicating an abnormal end of the TCB).

    * PROBLEM DESCRIPTION: CSQ3201E is issued reporting abnormal   *
    *                      end of task (EOT) when the CICS adapter *
    *                      is stopped using CKQC.                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When the CICS adapter is stopped, it issues an end context call
    to the queue manager, which schedules CSQCEOTE to run on any L8
    TCBs that are connected to the queue manager in parallel with
    the adapter continuing to stop.
    If the CICS adapter disconnects the QR TCB from the queue
    manager prior to CSQCEOTE disconnecting a L8 TCB, CSQ3201E is
    issued when CSQCEOTE attempts to disconnect the L8 TCB.
    

Problem conclusion

  • End context processing for the CICS MQ adapter is changed to
    prevent CSQ3201E being unexpectedly issued in this situation.
