Error description

  • The problem is  with the security using the DFSCCMD0 routine
    with commands entered from  the z/OS System Console (WTOR).
    When the DFSCCMD0 is entered, CCMD_RTRM is set as it is for
    any static or ETO terminals.
    So, there is no other way to differentiate the z/OS System
    Console than to test the CTTDEVIC being equal to CTTDSYSC.
    .
    Customer would like that at entry to the DFSCCMD0, the
    CCMD_RQSTTYPE be set to a value indicating the request comes
    from the WTOR (i:e: CCMD_RSYSC EQU 14  Z/OS Sytem Console)

    * PROBLEM DESCRIPTION: DFSCCMD0 is not distinguishing a        *
    *                      command from the z/OS system console    *
    *                      (WTOR).                                 *
    *                                                              *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    When entering commands from the z/OS System Console (WTOR),
    DFSCCMD0 is entered and CCMD_RTRM is set as it is for
    any static or ETO terminal.  But if the command is from
    the z/OS System Console, there is no way to differentiate
    it other than testing that CTTDEVIC being equal to CTTDSYSC.
    CCMD_RTRM needs to be set to represent the system console.
    
    Additional symptoms:
    DFS060I U0000 IS AN INVALID MESSAGE KEY when commands
    issued from WTOR on a system with ACF2's version of
    DFSCCMD0.
    ACFDCCM1 is rejecting commandsfrom the WTOR.
    ACF2 fix for this (updated exit) is TR54219.
    .
    CA Hyper RO54219 (04/03/2013 supersedes TR54219.
