PH32890: ABEND AICO SOMETIMES OCCURS WHEN AN EXEC CICS START IS ISSUED THAT SPECIFIES A USERID THAT HAS BEEN REVOKED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You have an application that issues many
  EXEC CICS START TRAN(tran) USERID(xxxxxxxx)
  This userid xxxxxxxx is revoked.  You notice different behavior
  from CICS.  Sometimes the START command fails with
  RESP=0069 - USERIDERR and RESP2=0019 -specified USERID xxxxxxxx
  is revoked.
  
  But other times the START command gets an OK response.
  During transaction intialization for the started tran, CICS
  finds the USERID xxxxxxxx is revoked.
  Because this occurred so early in the transaction
  initialization, it sets up the deferred abend code AICO.
  When transaction manager would normally give control
  to the first program for the transaction, it instead processes
  this deferred abend, giving control to DFHXMAB, and abends the
  task with ABENDAICO.
  This APAR is being taken to change the VALIDATE_USERID logic to
  handle a userid that CICS has received an ENF notification for,
  in the same way as a userid that is not currently in use in
  CICS.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Inconsistent behaviour with the EXEC    *
  *                      CICS START TRAN(tran) USERID(user)      *
  *                      command when the userid is revoked.     *
  ****************************************************************
  An application issues an EXEC CICS START command with the USERID
  option. The target userid has been revoked.
  If the userid was not currently in use in this CICS region, the
  START command returned USERIDERR RESP2=19.
  If the userid was currently in use in this CICS region; either
  signed on to a terminal, running a non-terminal task, or on the
  USRDELAY timeout queue, the START command returns OK. The target
  task abends AICO due to the userid being revoked.
  
  It is expected that the START command behaves the same in both
  cases and returns USERIDERR RESP2=19.
  

Problem conclusion

• CICS has been changed to always return USERIDERR RESP2=19 for a
  START command for a target userid that has been revoked.
