Tim Coninx [http://community.jboss.org/people/timconinxrvp] created the discussion "Re: recovering from invalid messages, selectively deleting from db" To view the discussion, visit: http://community.jboss.org/message/572505#572505 -------------------------------------------------------------- It seems that the problem has to do with messages staying in 'delivering' mode: When application code called by the MDB throws an exception, it seems that the message does not leave the state 'delivering'. A DLQ has been configured, and the messages end up succesfully over there, but still the original Queue has the problem. Code-wise, the MDB will only do a context.setRollbackOnly(); when it encounters a JMSException (I hope that's okay). Trying to remove all messages through the jmx console does not work as 'messages are still being delivered', with the exception java.lang.IllegalStateException: Cannot remove references while deliveries are in progress (Channel 13360), there are 1 And when stopping and starting the MDB (also when starting a server on the same db) we get the exception java.lang.IllegalStateException: Cannot remove references while deliveries are in progress (Channel 13360), there are 1 java.sql.SQLException: Invalid column index at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:208) at oracle.jdbc.driver.OracleResultSetImpl.getObject(OracleResultSetImpl.java:903) at org.jboss.resource.adapter.jdbc.WrappedResultSet.getObject(WrappedResultSet.java:750) at org.jboss.messaging.core.impl.JDBCPersistenceManager.loadFromStart(JDBCPersistenceManager.java:999) at org.jboss.messaging.core.impl.PagingChannelSupport.load(PagingChannelSupport.java:211) at org.jboss.jms.server.destination.QueueService.startService(QueueService.java:105) Starting the Queue, and in fact, the whole messageing subsystem, can then only be done after SQL deleteing the jbm_msg and jbm_msg_ref tables.
