<div class="jive-rendered-content"><p><span style="font-size: 10pt; ">Hi all,<br/> <br/> I am using JBoss AS 4.2.2.GA, JBoss Messaging 1.4.4.GA and JBoss ESB. I  have the following situation, five SQL commands of JBoss Messaging are  running non-stop, making an average of 800 commands every 5 seconds. The  commands are:<br/> <br/> INSERT_MESSAGE_REF=INSERT INTO JBM_MSG_REF (CHANNEL_ID, MESSAGE_ID,  TRANSACTION_ID, STATE, ORD, PAGE_ORD, DELIVERY_COUNT, SCHED_DELIVERY)  VALUES (?, ?, ?, ?, ?, ?, ?, ?)<br/> INSERT_MESSAGE=INSERT INTO JBM_MSG (MESSAGE_ID, RELIABLE, EXPIRATION,  TIMESTAMP, PRIORITY, TYPE, HEADERS, PAYLOAD) VALUES (?, ?, ?, ?, ?, ?,  ?, ?)<br/> UPDATE_ID_IN_CACHE=UPDATE JBM_ID_CACHE SET JBM_ID = ? WHERE NODE_ID = ?  AND CNTR = ?<br/> DELETE_MESSAGE=DELETE FROM JBM_MSG WHERE MESSAGE_ID = ? AND NOT EXISTS  (SELECT JBM_MSG_REF.MESSAGE_ID FROM JBM_MSG_REF WHERE  JBM_MSG_REF.MESSAGE_ID = ?)<br/> DELETE_MESSAGE_REF=DELETE FROM JBM_MSG_REF WHERE MESSAGE_ID=? AND  CHANNEL_ID=? AND STATE='C'<br/> <br/> Running a profiler on the application, 428.156 occurrences were recorded  for each command in 140 minutes and 7736 messages were delivered. In  this profile, I saw that commands are executed from a  ThreadPoolExecutor$Worker.run.<br/> <br/> This process is extremely active in Oracle and there is something wrong  with it, because even without traffic and no message, this high number  of commands are still executed.<br/> <br/> I separated the datasources for each component and saw that the  datasource is used in mbean <mbean  code="org.jboss.messaging.core.jmx.JDBCPersistenceManagerService"  name="jboss.messaging:service=PersistenceManager"... at  oracle-persistence-service.xml.<br/> <br/> <br/> Have someone an idea what could be causing this problem or if there is  any configuration that can stop this thread or even better, solve the  problem?<br/> <br/> <br/> Thanks for answering,<br/> Lucas Balensiefer</span></p></div>
