transaction context of the transaction that was rolled back or rolled
forwards. The application associated with this transaction was running with
Pid 74592 Tid 9117 under application name org.apache.nifi.NiFi and under user
identifier mqm. The following application context may also be useful in
identifying the application causing this behaviour CHANNEL(CH1) CONNAME(IP

We suppose there are some issues with "COMMIT" so I check the propertie
"Acknowledgement Mode=DUPS_OK_ACKNOWLEDGE (3)"  
  
What is the difference with "CLIENT_ACKNOWLEDGE (2)" ?  
  
Could we know how many messages consume by NIFI before it commit to the
MQServer ?  
Could we said to NIFI to commit every 100 or 1000 messages for example ?  
  
Thanks For help  
  
Regards
