JR34724: On UNIX platforms, ISF segment associated with a dsapi_slave was not removed if connection abnormally terminated.

APAR status

• Closed as program error.

Error description

• When client sessions are disconnected abnormally, the
  dsapi_slave processes stay out there in a  defunct state.  The
  adeb shared memory segment stays out there with an nattch of 1
  and the ISF memory map shared memory segment stays out there
  with an nattch of 0.  The customer kills the dsapi_slave
  processes manually and the adeb segments get an nattch of 0 but
  still stay there
  

Local fix

Problem summary

• On UNIX platforms at for IS 8.0.1, the ISF shared memory segment
  that
  is created for a DataStage client connection may not be removed
  if the dsapi_slave terminates abnormally.
  
    (This problem
  previously reported under ecase 119241.)
  

Problem conclusion

• Added code to dsapi_slave for ensuring that the shared memory
  segment is removed when the normal shutdown code in the
  DataStage server isn't executed due to a broken network
  connection or an abnormal condition in processing.
  

Temporary fix

• Remove unused shared memory segments manually if a job
  connection is broken.
