[jboss-jira] [JBoss JIRA] Resolved: (JBAS-6056) UserTransaction cannot be deployed as clustered proxy and sticky transactions randomly work

UserTransaction cannot be deployed as clustered proxy and sticky transactions randomly work ------------------------------------------------------------------------------------------- Key: JBAS-6056 URL: https://jira.jboss.org/jira/browse/JBAS-6056 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering, Transaction Manager (JBossTM) Affects Versions: JBossAS-4.2.3.GA, JBossAS-5.0.0.CR2 Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: JBossAS-5.0.0.GA When using sticky transactions calling clustered EJBs, user transaction currently uses a non-clustered proxy which means that UserTransaction (UT) calls will always land in the same node. This has a bad side effect in the case of dealing with clustered transaction sticky EJBs. If the UT and EJB calls landed on the same node, everything works fine: no matter how many EJB calls are done within a UT, they're all part of the same UT. If the UT lands on one node but all the sticky EJB calls land on a different node, each EJB invocation is effectively treated as a separate transaction because the tpc (transaction propagation context) does not exist in that node. UserTransaction needs to be able to be deployed with a clustered proxy that supports sticky transactions in the sense that: - Wherever ut.begin() lands, the EJB invocations within it and other ut operations (ut.commit(),ut.rollback()...etc) must land in the same node. - Consecutive ut.begin() calls are free to land on different nodes, based on what the lbp is. For example, in the case of TransactionStickyRoundRobin, the next ut.begin() call will land on the next node in the view of the cluster.
