Persistent services are very noisy in the logs when the table(s) they are trying to create already exists --------------------------------------------------------------------------------------------------------- Key: JBMESSAGING-218 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-218 Project: JBoss Messaging Issue Type: Sub-task Components: Messaging Core Persistence Reporter: Ovidiu Feodorov Priority: Minor Fix For: Unscheduled Original Estimate: 4 hours Remaining Estimate: 4 hours JDBCDurableSubscriptionStore, JDBCMessageStore, JDBCTransactionLog try to create their corresponding tables during their inialization procedure and litter the logs with SQLException stack traces if the corresponding tables exist: java.sql.SQLException: Table already exists: TRANSACTION in statement [CREATE TABLE TRANSACTION] at org.hsqldb.jdbc.Util.sqlException(Util.java:61) at org.hsqldb.jdbc.jdbcStatement.fetchResult(jdbcStatement.java:1580) ..... Use a less noisy way to insure the tables exist. Swallowing the SQLException is not a solution, since it may signal other problems with the database.
