I have a BMT, there was no transaction defined in it, which made it to mix up data when dealing with multiple clients.

I have created a userTransaction to rectify this problem, but after adding the transaction, I started getting following error,

javax.resource.ResourceException: This Managed Connection is not valid as the phyiscal connection is not usable .

So I changed the parameter, is-connection-validation-required = “true”.

I am not facing issues so far.

But I have two questions :

1. Will this make my system unstable?
2. Does the parameter changing have any performance issues?

This is a critical situation.
Any help is highly appreciated.

Thanks in Advance.
