We are seeking advice for sharing 2nd-level cache between cluster nodes using Tomcat, Spring, and Hibernate. If you have been successful doing this, we'd appreciate hearing from you. We'd also appreciate learning about dead-ends we might avoid. Our configuration: -- Tomcat 6.0.14 -- Spring 2.0.4 -- Hibernate 3.2.5 -- Spring-supplied HibernateTransactionManager -- JBoss Cache 1.4.1.SP9 (JBC) Our experiences to date: -- pessimistic locking and replication sync work well, except under moderate load where we get ReplicationException's and missing updates to the database. -- async and invalidation_sync did not replicate our caches correctly Specific questions we have: Will it be possible to use JBC reliably using a non-JTA transaction manager such as HibernateTransactionManager? If a JTA transaction manager should be used, which one would you recommend? Thanks in advance for your help.
