Georg Waldschmidt [http://community.jboss.org/people/waldsgbq] created the discussion "Database reconnect failed for JBoss/JBPM" To view the discussion, visit: http://community.jboss.org/message/635439#635439 -------------------------------------------------------------- We are using JBoss-5.1.0.GA, JBPM 4.4 and Oracle 11g. When we try to test the database reconnect abilities (by disconnecting the network connection between JBoss and the Oracle server), After reestablishing the network connection, JBPM doesn't reconnect properly. Starting a new business process instance ends in an exception: 2011-11-07 17:34:34,041 ERROR [pool-24-thread-2] (Log4jLog.java:42) failed to execute job: 10500 org.jbpm.api.JbpmException: invalid transaction state: STATUS_ROLLING_BACK at org.jbpm.pvm.internal.tx.JtaTransactionInterceptor.execute(JtaTransactionInterceptor.java:59) at org.jbpm.pvm.internal.tx.JtaRetryInterceptor.executeWithoutRetry(JtaRetryInterceptor.java:56) at org.jbpm.pvm.internal.tx.JtaRetryInterceptor.execute(JtaRetryInterceptor.java:48) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.executeInNewEnvironment(EnvironmentInterceptor.java:53) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute(EnvironmentInterceptor.java:40) at org.jbpm.pvm.internal.svc.SkipInterceptor.execute(SkipInterceptor.java:43) at org.jbpm.pvm.internal.jobexecutor.JobParcel.run(JobParcel.java:48) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) Has anyone any idea on how to ensure that JBPM's job executor proceeds processing new jobs (and ideally jobs that got interrupted) after a database connection interrupt? We would expect, that JBoss's managed connection pool takes care of connections affected by the interrupt.
