SELECT_COUNTER SQL statement in db2-persistence-service.xml is not correct -------------------------------------------------------------------------- Key: JBMESSAGING-1875 URL: https://issues.jboss.org/browse/JBMESSAGING-1875 Project: JBoss Messaging Issue Type: Bug Components: Messaging Core Persistence Affects Versions: 1.4.8.GA, 1.4.0.SP3.CP12 Reporter: Yong Hao Gao Assignee: Yong Hao Gao Fix For: 1.4.0.SP3.CP13, 1.4.8.SP1 SELECT_COUNTER statement should acquire proper lock to prevent concurrent read before transaction committed. This is required in JBM updating the JBM_COUNTER table. Current: SELECT_COUNTER=SELECT NEXT_ID FROM JBM_COUNTER HOLDLOCK WHERE NAME=? The HOLDLOCK doesn't have any effect on locking. The correct one: SELECT_COUNTER=SELECT NEXT_ID FROM JBM_COUNTER WHERE NAME=? WITH RS USE AND KEEP EXCLUSIVE LOCKS -- This message is automatically generated by JIRA.
