When i change the default db schemas of jbm tables the DLQ - if it contains message - run in deadlock by the next server restart, because it wants to use the default schema instead of the modified db schema ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBMESSAGING-1780 URL: https://issues.jboss.org/browse/JBMESSAGING-1780 Project: JBoss Messaging Issue Type: Bug Affects Versions: 1.4.0.SP3.CP09, 1.4.5.GA, 1.4.6.GA Environment: JBoss 5.1.GA+Seam 2.1.1.GA+mysql 5.1 Reporter: bb bb Assignee: Yong Hao Gao Fix For: 1.4.0.SP3.CP15, 1.4.8.SP11 At first, I modified the default schema of jbm tables in mysql-persistence-service.xml so, I changed the sql properties JBM_DUAL to newSchema.JBM_DUAL and so on... Everything works fine with the modified schema, until I add a posion message to the dead letter queue. Then I want to restart the JBoss server, I get an exception to it run in dead lock, because didn't find the jbm_msg tables (but it would be newSchema.jbm_msg )
