Error description

  • Comproute of PH52408.
    Customer reported that when he executes this command to start a
    transaction:
    EXEC CICS START TRANSID('RVRD') AFTER MINUTES(10) END-EXEC
    
    If the transaction (RVRD in this case) is defined with
    DYNAMIC=YES then he saw that the transaction for the
    corresponding ICE is CDFS (instead of RVRD)
    And with CECI INQUIRE REQID it returns TRANSID('CDFS').
    .
    If the transaction RVRD is defined with DYNAMIC=NO then the ICE
    shows the correct transaction RVRD.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All CICS users.                              *
    ****************************************************************
    * PROBLEM DESCRIPTION: CDFS transaction is being attached for  *
    *                      every non-terminal-related deferred     *
    *                      START in non-routing regions leading to *
    *                      MAXTASK condition in CICS.              *
    ****************************************************************
    If the user transaction to be started is eligible for dynamic
    routing, system transaction CDFS will run and start the user
    transaction at the time specified by INTERVAL, AFTER, AT or TIME
    option of EXEC CICS START command.
    CICS TS 5.5 onwards in order for a non-terminal-related START
    request to be dynamically routed the target transaction needed
    to be defined as DYNAMIC(YES) with a routing program, specified
    by either DSRTPGM or DTRPGM.
    The value of system initialization parameter DSRTPGM supplies
    the name of a routing program.
    The transaction defined as DYNAMIC(YES) with DSRTPGM=NONE
    indicates that no routing is expected. However, the CDFS
    transaction is still being attached for all non-terminal-related
    EXEC CICS START requests that specified an INTERVAL and may lead
    to hitting MAXTASK condition in CICS region.
    This is a comproute of PH52408.
    

Problem conclusion

  • CICS has been changed so that the CDFS transaction is only
    attached when a routing program has been defined and the
    transaction is defined as DYNAMIC(YES).
