Hello All,

I have a spring 3/hibernate 4 applications that has been running for couple of years. In the past month upgraded to spring 4 and hibernate 5 with no code changes. Of course, functionality tests have been performed for regression. However, after the release it appears that database is receiving more "rollback" operations than before the upgrade. We have then downgraded back to hibernate 4 (while leaving spring and other intact). Wonder where to start to find out what is causing this. Most of these rollback operations are coming from mostly "Select" calls. Thanks.

You should investigate what triggers the rollback. Usually, it is a failure on the database side that triggers a rollback, like a constraint violation or an optimistic lock exception. Try finding the reason for the rollback. Otherwise, it's impossible to tell what's to be done.

Thanks for the response. After investigating with DBA, it appears application is triggering the rollback. When switched back to hibernate 4 it doesn't anymore. I am using hibernate 5.1.2.

Maybe, it's a Spring issue. You must use a Spring version that's compatible with Hibernate 5.1.2.
