  If CICS is responding to replication log data by applying file
  control changes from the replication log, transaction CFC1
  issues the file control requests. If the target file is remote,
  then these are function shipped to the FOR. DFHFCLJ has code to
  prevent further replication logging for such work, as it is
  being driven as the result of replication logging. It checks for
  the transaction to not be CFC1 before writing replication log
  data for the file control requests. However, for function
  shipped requests, the transaction will be CSMI and not CFC1, so
  this check fails and replication data is written.

Problem conclusion

Temporary fix

• FIX AVAILABLE BY PTF ONLY
  

Comments

• DFHFCLJ has been changed to check for the original transid that
  led to the CSMI task being attached. If it was CFC1 then
  replication logging is avoided in this case.
