What is the steady-pool-size?

Under any condition, the max pool size will not exceed what is
configured in the connection
pool configuration. It could be that for 4 connections, MQ might be
using 2 connections each
to the database. Also, it is possible that there is one house keeping
connection created always
between MQ client and server.
Have you tried increasing the max pool size to say 15 and checked the
number of tcp connections?
Also, how are you checking the tcp connections? netstat?
thanks,
