Hi Binod,
The connection pooling is fine, I was able to set it via that page. I was
testing the JMS Pooled connections today and it was doing what it is
supposed to do. It's just that the physical connections doesn't match up to
physical connections.
The tool i'm using is sys internals to view the physical connections which
is essentially netstat I guess(?)
I was reading through the genericra user guide again and saw that the
Connection Exception Handlling is not yet tested successfully? Is this still
the case? Have you got test cases that you would like me to test between
SJSAS and MQSeries, I would be happy to offer my services if you require?
anyway, thanks for your help
Jonathon
