Atomikos Forum

Hello all,
we have a question about the com.atomikos.icatch.threaded_2pc setting.
We recently upgraded from TransactionEssentials 3.6.5 to 3.8, so according to:
http://www.atomikos.com/Documentation/JtaProperties#Threading
the default value for this setting changed from true to false.

Following this upgrade, performance went down on our production environment. We set the value back to true, restarted our webapps, and everything went back to normal.

But the documentation says: "For maximum compatibility with JDBC and JMS implementations: set this property to false (i.e., disable threaded commits)."

We're using JDBC. What could be the consequences of having this setting set to true instead of false ?

We're using Postgres Databases, Hibernate and Spring.

Thanks for your help,
Phil
