Hi Sharma
I will try that (turn off the dedicated task runner) and advise, please see
below the answers to the questions that you have asked.
1. how many processors/cores do your machines have?
16 cores
2. are your clients (producers/consumers) local to the broker on the same
machine but different process?
All our consumers are remote, different applications sitting in
different departments (but in the same DMZ). Some of our producers are local
and some remote. We use these messages to kick
Different business work flows in different fulfilment areas
3. looking at the oracle-ds settings in config, is the same machine also
hosting oracle?
The Oracle database is sitting in a different machine but in the same
DMZ
4. what nic does the machine have?
I will have to find this out from our infrastructure guys.
Regards,
P
