Error description

  • When CEDX AAAA is entered the user transaction AAAA is using
    the tranclass(DFHEDFTC).
    We can see it with CEMT I Transaction(AAAA) .
    If we disconnect from your terminal and reconnect the
    transaction is still with the TRANCLASS(DFHEDFTC).
    If you shutdown CICS and restart it in emergency the transaction
    AAAA is always with the TRANCLASS(DFHEDFTC).
    The problem is that this TRANCLASS have a MAXACTIVE=10 and it
    can be a bottleneck if this transaction is a lot use and the
    customer does not know that the transaction stays with the
    TRANCLASS DFHEDFTC.
    

Local fix

  • To change the TRANCLASS DFHEDFTC with the initial TRANCLASS

    * PROBLEM DESCRIPTION: A transaction with CEDX active may      *
    *                      retain DFHEDFTC tranclass.              *

    ****************************************************************
    'CEDX TRA1' entered on a CICS session will drive DFHEDFP and it
    will assign a temporary TRANCLASS of DFHEDFTC to TRA1. Usually
    the user would then invoke the transaction under CEDX and at
    task end would then have the choice of continue or discontinue
    running TRA1 under CEDX. If the latter is chosen then DFHEDFP
    will restore the original TRANCLASS value.
    
    However, if TRA1 is not run under CEDX (for example, CICS is
    SHUTDOWN IMMEDIATE then emergency restarted) then the temporary
    TRANCLASS of DFHEDFTC assigned to TRA1 is restored from the
    catalog. TRA1 will now have a TRANCLASS of DFHEDFTC which has a
    MAXLIMIT of 10 specified. This can lead to unexpected
    throttling.
    

Problem conclusion

  • DFHXMXD has been modified so that any transaction that has been
    activated to run under CEDX will not have the temporary
    TRANCLASS of DFHEDFTC cataloged. This will ensure DFHEDFTC is
    not restored as the TRANCLASS over an emergency restart.
