PM35939: FLUSHTYPE=COUNT TABLE FLUSH SETTING FOR IMS LOG PROCESSING LOST WHEN DRLLOG FILE HAS CONCATENATED DATA SETS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• FLUSHTYPE=COUNT table flush setting for IMS log processing lost
  when DRLLOG file has concatenated data sets. The problem occurs
  for any log file in the concatenation after the first such that
  flush processing is disabled until the number of records
  processed from the current file exceeds the total number of
  records processed the last time table flush processing was
  invoked. Depending on the number of records in each file in the
  concatenation this can mean that table flush processing is
  disabled for each file in the concatenation after the first.
  

Local fix

• Combine all logs into a single file to avoid concatenation.

  * RECOMMENDATION: APPLY THE PTF FIXING THIS APAR               *
  ****************************************************************
  For FLUSHTYPE=COUNT=nnnn a buffer flush occurs when the
  current record count is a multiple of the FLUSHTYPE=COUNT=nnnn
  value and the current record count is greater than the
  record count when the last buffer flush occurred.
  The problem is the record count is being reset at the start
  of the processing for each new DD, hence the flush mechanism
  is not functioning correctly.
  

Problem conclusion

• The problem with the current record count is corrected thus
  correcting the problem with the FLUSHTYPE=COUNT buffer flush
  mechanism.
  Count errors for messages DRL2053I, DRL0310I
  and DRL0311I have been corrected.
