sysview CTASKS inconsistent data

    Hi,

    We are comparing Transaction which are schedule in control-m with sysview  in panel CTASKS  thru rexx  and time to time TRAN  in CTASK panel dissapear and we got false alarm.

    Detail description:

    In practise it means controlled execution of a transaction on a named CICS. Only one thread can be active at a time on a CICS region.
    The process is initiated by a batch job that issues a wake-up
    event, e.g.
    CITHRD 'J071W01A TULOS0 A 16-07-2019 999 Y N N'

    (for migration, also:)
    EX CITHREA3 'J071W01A TULOS0 A 16-07-2019 999 Y N N'

    OPS traps the event and starts the thread on CICS, e.g.
    F J071W01A,D208 TULOS0,A,16-07-2019,999,Y,N,N

    When CICS has accepted the thread, messages are issued:
    +PD201P0 -0040I-E:Dispatcher (CICS task 0092046) st
    +
    +D208 TULOS0,A,16-07-2019,999,Y,N,N
    +D2081E - Dispatcher Control.
    +*-----------------------------------------------------------
    +* Profile : TULOS0 Process option: A
    +* Date : 16/JUN/2019 Priority: 999 Autodeactivate: Y
    +*-----------------------------------------------------------
    +PD208I0 -0015I-E:Dispatcher activated.

    The task which number is on "PD201P0 -0040I" is supposed to be
    active until the thread is terminated:
    +PD201P0 -0039I-E:Dispatcher (CICS task 0092046) sh

    This number is compared from ctm message and  sysview CTASKS panel by XVEXTRAC Task#  


    When CICS notifies the termination of the thread, a CONTROLM cond
    is set:
    COND TULOS0-OK ODATE 1607 ADDED
    COND IT-TULOS0-OK ODATE 1607 ADDED


     it was working for a quite long time but it seem lately it makes lot of false alarm because numbers are not correct and it's not shown in sysview
    Did you have any similair problem ? Was in sysview 15.0 ptf 7 some changes in CTASKS panel ?

    Martin,
    Feature PTF 7 SO01737 did cause a problem related to CTASKS.  See PTF SO05678 for the correction.

    Hi,

    we finally had service window in our production system so we install the latest PTFs (also SO05678) but this problem still occures, Do you have any suggestion ?



    I have one other question. I have checked the PTF thru camodid cmd (camodid dsn(HLQ.SYSVIEW.CNM4BLOD) ptf(SO05678)) and it's there. That's fine but when i put LISTMOD in sysview  i cannot find in FIXLEVEL collumn that PTF and also that modules

    GSVC0TAS
    GSVC1TAS
    GSVC6TAS
    GSVC7TAS
    GSVC8TAS
    GSVC9TAS

    but they are in *blod dataset   shouldnt it be there if sysview using those ?

    Those particular modules get loaded in each CICS region E-PVT area, so they (the one that matches the level of your target CICS asid) will show on CMODS rather than LISTMODS.  However, I do not recall having seen a problem where CTASKS was totally missing an active transaction.  Maybe check the start/end range in the resulting transaction record against when this REXX exec ran.  I'd suggest opening a support case if you need further assistance with this.
