Persistence Manager Improvements -------------------------------- Key: JBAS-1339 URL: http://jira.jboss.com/jira/browse/JBAS-1339 Project: JBoss Application Server Issue Type: Task Security Level: Public(Everyone can see) Components: JMS service Affects Versions: JBossAS-4.0.1 Final, JBossAS-3.2.7 Final Reporter: Adrian Brock There are a number of improvements that can be made to the persistence manager. This should really be done by writing a new version that can then be optionally used while it is experimental. 1) Make use of the datasource mappings - similar what has been done for the EJB timer 2) The use of the JTA transaction is unnecessary since we are the only one in the transaction branch. The tranaction still needs suspending so we are isolated from any wrapping transacton. 3) Make use of build writes to the database This can be used for transactional sessions where multiple messages are processed But it could also be used where people want to relax the absolute requirement that messages are persisted in return for some performance improvement. 4) A general review/rewrite of where the persistence manager is invoked from the server with an aim to improve performance.
