PH40714: TERMERR AND ATNI AND DFHZC3440 ON AN ISSUE DISCONNECT FOLLOWING A SEND LAST WAIT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You get a TERMERR condition and abendATNI and a DFHZC3440
  message on an EXEC CICS ISSUE DISCONNECT that follows an EXEC
  CICS SEND LAST WAIT.  This happens only after you migrate to
  CICS/TS 5.5 or above.
  
  The following code snippet recreates the problem when running as
  a terminal-initiated transaction:
  
          MVC  REC8,=C'Hello!'
          MVC  LEN,=X'0006'
          EXEC CICS SEND FROM(REC8) LENGTH(LEN) LAST WAIT RESP(OK)
          EXEC CICS ISSUE DISCONNECT
          EXEC CICS RETURN
  

Local fix

• Change your program to not specify LAST or not specify WAIT on
  the SEND prior to the ISSUE DISCONNECT
  

Problem summary

  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: An EXEC CICS ISSUE DISCONNECT command   *
  *                      that follows an EXEC CICS SEND LAST     *
  *                      WAIT receives a TERMERR condition and   *
  *                      ATNI abend.                             *
  ****************************************************************
  An ATNI abend and message DFHZC3440 is received when an EXEC
  CICS ISSUE DISCONNECT command is issued after an EXEC CICS SEND
  LAST WAIT.
  
  CICS prevents further Terminal Control commands being issued
  when either an ABEND, TERMERR or a Terminal Control FREE is
  pending. This protects CICS from unpredictable errors and
  behaviour that can occur when further Terminal Control commands
  are issued against a terminal after one of these conditions has
  been set.
  
  However, certain terminal control commands such as ISSUE
  DISCONNECT should be handled if issued after these events.
  

Problem conclusion

• CICS has been changed to ensure that an EXEC CICS ISSUE
  DISONNECT command will be handled even if an ABEND, TERMERR or a
  Terminal Control FREE is pending.
