Sun Java System Message Queue 4.2 Release Notes

Persistent Data Store Format Change

Message Queue 4.1 changed the JDBC-based data store to support high-availability broker clusters. For this reason the format of the JDBC—based data store is increased to version 410. Format versions 350, 370, and 400 are automatically migrated to the 410 version.

Please note that the format of the file-based persistent data store remains at version 370 because no changes were made to it.
