[rules-users] Two Guvnor instances sharing repository

Hi Guys, I have two guvnor instances. They are using a mysql db repository. I would like both to point to the same database. I configured them both to use the same database in the repository.xml, but it starting throwing errors and they were not in sync. Errors are like this 11:43:29,597 WARN [com.arjuna.ats.arjuna] (Transaction Reaper) ARJUNA012117: TransactionReaper::check timeout for TX 0:ffff7f000101:55ee0fc5:527e486a:3f in state RUN 11:43:29,599 WARN [com.arjuna.ats.arjuna] (Transaction Reaper Worker 0) ARJUNA012095: Abort of action id 0:ffff7f000101:55ee0fc5:527e486a:3f invoked while multiple threads active within it. 11:43:29,601 WARN [com.arjuna.ats.arjuna] (Transaction Reaper Worker 0) ARJUNA012108: CheckedAction::check - atomic action 0:ffff7f000101:55ee0fc5:527e486a:3f aborting with 1 threads active! 11:43:29,602 WARN [com.arjuna.ats.arjuna] (Transaction Reaper Worker 0) ARJUNA012121: TransactionReaper::doCancellations worker Thread[Transaction Reaper Worker 0,5,main] successfully canceled TX 0:ffff7f000101:55ee0fc5:527e486a:3f 11:44:37,245 INFO [org.apache.jackrabbit.core.query.lucene.IndexMerger] (jackrabbit-pool-5) merged 791 documents in 568 ms into _p. 11:44:37,377 INFO [org.apache.jackrabbit.core.query.lucene.IndexMerger] (jackrabbit-pool-2) merged 1370 documents in 709 ms into _o. 11:48:07,300 WARN [org.jboss.seam.transaction.TransactionServletListener] (http--127.0.0.1-8080-5) Error starting the transaction: javax.transaction.NotSupportedException: BaseTransaction.checkTransactionState - ARJUNA016051: thread is already associated with a transaction! at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.begin(BaseTransaction.java:63) at com.arjuna.ats.jbossatx.BaseTransactionManagerDelegate.begin(BaseTransactionManagerDelegate.java:65) at org.jboss.tm.usertx.client.ServerVMClientUserTransaction.begin(ServerVMClientUserTransaction.java:142) at org.jboss.seam.transaction.UTTransaction.begin(UTTransaction.java:51) [seam-transaction-3.1.0.Final.jar:3.1.0.Final] at org.jboss.seam.transaction.DefaultSeamTransaction.begin(DefaultSeamTransaction.java:88) [seam-transaction-3.1.0.Final.jar:3.1.0.Final] at org.jboss.seam.transaction.TransactionServletListener.requestInitialized(TransactionServletListener.java:110) [seam-transaction-3.1.0.Final.jar:3.1.0.Final] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:143) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [jbossweb-7.0.13.Final.jar:] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:368) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877) [jbossweb-7.0.13.Final.jar:] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:671) [jbossweb-7.0.13.Final.jar:] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930) [jbossweb-7.0.13.Final.jar:] at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0_21] Caused by: java.lang.IllegalStateException: BaseTransaction.checkTransactionState - ARJUNA016051: thread is already associated with a transaction! at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.checkTransactionState(BaseTransaction.java:257) at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.begin(BaseTransaction.java:59) ... 13 more I also tried both instances to also share the repository folder, both this is failing because it lockes the file Caused by: javax.jcr.RepositoryException: The repository home /home/calcacuervo/development appears to be in use since the file named .lock is locked by another process. at org.apache.jackrabbit.core.util.RepositoryLock.tryLock(RepositoryLock.java:166) Any idea on how could I do it?
