There's little helpful information. I don't know what in my app it might be associated with. I've restarted my machine, checked any jms queues that do db activity for stuck messages (none), and looked at the Oracle docs for in-doubt transactions (not applicable.) I've also looked at the known issues page but don't see the ORA-1591 messages listed there. The only db activity my app does is with jms messages. I'm using WLS 8.1sp4, the included Sun jdk, Oracle 9.2.0.1, and BEA's Oracle driver. The error is printed many times every few seconds. I think I saw this once before and it eventually "times-out." Any idea what can be causing it or what I can do about it? thanks john java.sql.SQLException: [BEA][Oracle JDBC Driver][Oracle]ORA-24756: transaction does not exist at weblogic.jdbc.base.BaseExceptions.createException(Unknown Source) at weblogic.jdbc.base.BaseExceptions.getException(Unknown Source) at weblogic.jdbcx.oracle.OracleImplXAResource.commit(Unknown Source) at weblogic.jdbcx.base.BaseXAResource.commit(Unknown Source) at weblogic.jdbc.jta.DataSource.commit(DataSource.java:971) at weblogic.transaction.internal.XAServerResourceInfo.commit(XAServerResourceInfo.java:1291) at weblogic.transaction.internal.XAServerResourceInfo.commit(XAServerResourceInfo.java:519) at weblogic.transaction.internal.ServerSCInfo$2.execute(ServerSCInfo.java:374) at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:219) at weblogic.kernel.Kernel.executeIfIdle(Kernel.java:387) at weblogic.transaction.internal.ServerSCInfo.startCommit(ServerSCInfo.java:364) at weblogic.transaction.internal.ServerTransactionImpl.localCommit(ServerTransactionImpl.jav a:1883) at weblogic.trans

begin MQBEGIN start xastart xa_start xa mqminfo XA JAVA 2 phase commit syncpoint Technote (troubleshooting) Problem(Abstract) You have a WebSphere MQ Java™ application using a JDBC XA connection. The application does an MQBEGIN and reads http://www.ibm.com/support/docview.wss?uid=swg21137061 some messages from a queue using the MQ Java classes. The application then does some http://www.javamonamour.org/2015/10/ora-24756-transaction-does-not-exist.html database updates, which are committed, and then you receive the following error: ORACLE XA: Version 8.1.7.0.0. RM name = 'Oracle_XA'. 123757.70410.1: ORA-24756: transaction does not exist Error Meaning: ORA-24756 transaction does not exist Cause: An invalid transaction identifier or context was used or transaction has completed. Action: Supply a valid identifier if the transaction has not completed and retry oracle error the call. Symptom The final transaction does not commit properly, and the preceding ones only commit after doing the next begin(). After populating the application's input queue with several transactions, the program does the following loop : a) MQ begin b) MQ get c) Some database transactions d) MQ put e) MQ commit f) Sleep one minute During the sleep the results of steps 'a' through 'e' do not appear to have worked. Following oracle error 24756 the next loop round (presumably after the begin) the transaction commits. Cause JServer not installed properly on Oracle (even though SQL*PLUS indicates it is). Diagnosing the problem The MQ trace does show a commit being done, but it completes with a zero reason code and there were no other error messages showing up in MQ. When the MQBEGIN occurs, an RMID of 1 is specified but we then find no associated connection to an XA resource manager associated with that RMID - this is allowed to proceed. There is a call to getJDBCConnection happening on a specific MQQueueManager object which succeeds in connecting, but it notes that we are not in a transaction, so it puts this XA connection into a list of spare XA connections. Just after this in the trace, there is a MQBEGIN call coming in on a different MQQueueManager object. This successfully issues the XA_OPEN (we also see that in the Oracle trace output) but it is unable to issue the XA_START (which is not seen in the Oracle trace) because it can not find an associated XA connection. Following on from this, the commit(), which is issued on the 2nd MQQueueManager object only commits the work on MQ. Presumably at some point after all of this has occurred, Oracle recognizes that there is a prob

You must carefully craft the various timeouts in WebLogic and in Oracle DB. See Oracle note "Troubleshooting ORA-24756 while Running an XA Program or MSDTC with the Oracle RDBMS (Doc ID 1076242.6)". THE rule is: global transaction timeout < session timeout < distributed_lock_timeout . See also "Recommended Timeout Configuration When Using an External Transaction Processing Monitor and XA with Oracle (Doc ID 338880.1)" . Each MDB has a specific timeout, but this should not be involved in the issue (this in the weblogic.ejb.jar.xml DD https://docs.oracle.com/cd/E13222_01/wls/docs103/ejb/DDreference-ejb-jar.html )
