PK49081: LG0772 DUMP SUPPRESSION FOR RC4, RSN404

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a DFHLG0772 message occurs with reason code 4, response
  code 404, a LG0772 dump is automatically taken.  These MVS
  Logger rc/rsn codes are expected so the dump is not needed
  when the xmem environment fails and should be suppressed.

  ****************************************************************
  When CICS disconnects from a logstream, an IXGCONN disconnect
  call is made to the z/OS Logger. If a disconnect request is
  already taking place for  some reason, the z/OS Logger will
  give a return code of 4 (warning), with a reason code of 404
  (which means IxgRsnCodeDisconnectInProgress). The CICS Log
  Manager treats any non zero return code as serious enough to
  issue message DFHLG0772 and request an associated system
  dump. The overhead of a system dump is not justifiable for such
  a basic warning, and only the message is required.

Problem conclusion

• The CICS Log Manager has been changed to issue DFHLG0772 without
  an accompanying system dump if a disconnect request receives
  rc4, rsn404 from the z/OS Logger.
