I recently worked on application that used Hibernate as JPA provider and using an Oracle database and deploy the application on a WebSphere application server 6.1 server.
my application ran a lot of transactions per second ,all of them were running successfully but one in the middle did not committed (i notice that balance not changed), no problem happened or exception in logs, it happened randomly.
I did not configure where the problem persist , from application server or from my application or even from hibernate.
