I am quite sure there is a way to configure the connection to expire for
different reasons, at which time they are closed and new ones are used.  I
don't know enough WebSphere to help further in that area though.

Anyone?

Richard-

In that case I am suprised Alex had the problem which they had (server
brought to its knees after a few days). That must mean that the Connections
in the pool they were using were being kept alive for longer than a few
days, allowing many statements which are no longer used to remain alive. I
guess this is valid, but a "safe" solution to the problem would be to have
the connection manager close connections and replace them with new ones
after a given set of circumstances (example: they have been used twice,
they
are more than 2 hours old, etc..) I don't recall specically, but I think
something like this is configurable within the connection manager?
