[jboss-jira] [JBoss JIRA] Created: (JBAS-5189) Txn-Manager arjuna commits data after timeout in long transactions

Txn-Manager arjuna commits data after timeout in long transactions ------------------------------------------------------------------ Key: JBAS-5189 URL: http://jira.jboss.com/jira/browse/JBAS-5189 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Components: Transaction Manager Affects Versions: JBossAS-4.2.0.GA Reporter: Rￃﾼdiger Schmitz Assigned To: Adrian Brock We encountered the following situation: Within an ejb using hibernate (and it's JTA transaction manager) we execute a long transaction. When the transaction run-time exceeds the arjuna timeout, the container outputs the following message: After this, all following operations are directly committed to the database! So, basically we have two problems: - The timeout of the txn-manager triggers, even while the current database transaction is in continuous heavy use (numerous inserts/selects per second) - Instead of aborting with an exception at once, the transaction manager happily carries on accepting data - The data sent to the database _before_ the timeout is discard - The data sent to the database _after_ the timeout is committed to the database. This results in inconsistent data within the database - After the ejb-method commits an exception is thrown, leaving the database in an inconsistent state. A workaround is of course to increase the transaction manager timeout, but this defeats the purpose of the timeout. Furthermore, the duration of a transaction cannot always be estimated. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
