PK93593: DUPLICATE DFHZC3462 MESSAGE BEING ISSUED FOR THE SAME DEVICE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• During the processing of the first message DFHZC3462, DFHZNAC
  exit A21 scheduled DFHZOPN, TCTECOR, to run because TCTECLG is
  on. TCTECLG was turned on when the CINIT was rejected by
  DFHZLGX. DFHZOPN uses TCTECID to do the OPNDST. TCTECID has
  been set with nulls by DFHZCLS clean-up (First message
  DFHZC3462). This causes the duplicate DFHZC3462 message.

  ****************************************************************
  The CICS/VTAM LOSTERM exit DFHZLTX was driven for a terminal
  resulting in message DFHZC2410. The transaction running at the
  terminal ABENDed ATNI and the terminal was scheduled for CLSDST
  processing, message DFHZC3462 session closed.
  During ABEND processing the terminal attempted to log back on to
  CICS. The CICS/VTAM logon exit DFHZLGX was driven and set flag
  TCTECLG to indicate that a CLSDST and LOGON request were in
  progress. In response to the logon DFHZOPN ran for OPNDST
  processing. However the original CLSDST processing was not fully
  complete and the BIND request from CICS was rejected (RPLFDBK
  '0009'x). The failed BIND request and subsequent cleanup caused
  a second DFHZC3462 message for the same LU.

Problem conclusion

• DFHZLGX has been changed for the reported problem so that a
  logon request received during CLSDST processing will be
  rejected.
