PM69539: DFSCCMD0 SECURITY AND THE Z/OS SYSTEM CONSOLE (WTOR).

Obtain the fix for this APAR.

APAR status

• Closed as program error.

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)

  ****************************************************************
  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.
  
  After applying this APAR (PM69539) the following problems
  could occur:
  #1 ----------
  DFS060I U0000 IS AN INVALID MESSAGE KEY when commands
  issued from WTOR on a system with ACF2's version of
  DFSCCMD0.
  .
  ACFDCCM1 is rejecting commands from the WTOR.
  ACF2 fix for this (updated exit) is TR54219.
  .
  CA Hyper RO54219 (04/03/2013 supersedes TR54219.
  #2 ----------
  Additional information for Users of IMS ETO
  support V3.1 (ETOS)
  - After applying this APAR (PM69539) users receive
  message "DFS3662W hh:mm:ss COMMAND REJECTED BY DFSCCMD0"
  for commands entered from the z/OS system console.
  IZTCCMDZ requires update. Apply ETOS APAR PM76074/UK90989
  to correct.
  #3 ----------
  Users of RACF and a customized version of IBM's DFSCCMD0 User
  Exit:
  DFS060I U0000 IS AN INVALID MESSAGE KEY when commands
  issued from WTOR on a system with a customized version of
  DFSCCMD0 that has not been changed to include the new code added
  by this APAR.
  

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  DFSICIO1 has been modified to change the command request type
  to '14'x indicating the request comes from the z/OS system
  console (WTOR).
  
  DFSCCMD0 has been modified to recognize a z/OS console
  request.
  
  DFSCCMD has been modified to add flag CCMD_RSYSC.
