I've managed (finally) to enable logging (that would be another topic of discussion apparently). With the default settings: comm.arjuna.ats.arjuna.coordinator.txReaperTimeout=120000 com.arjuna.ats.arjuna.coordinator.txReaperMode=NORMAL I'm just seeing a Repear thread working every 5 seconds, so I don't know what this txReaperTimeout actually does. Maybe it is microsecs by it defaults to 5 secs minimum??? | sleeping for 5000 | 2007-06-19 22:24:33,542 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] TransactionReaper::check () | 2007-06-19 22:24:33,542 DEBUG [com.arjuna.ats.arjuna.logging.arjLoggerI18N] [com.arjuna.ats.internal.arjuna.coordinator.ReaperThread_1] - Thread Thread[Thread-4,5,jboss] | sleeping for 5000 | 2007-06-19 22:24:38,549 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] TransactionReaper::check () | 2007-06-19 22:24:38,549 DEBUG [com.arjuna.ats.arjuna.logging.arjLoggerI18N] [com.arjuna.ats.internal.arjuna.coordinator.ReaperThread_1] - Thread Thread[Thread-4,5,jboss] | sleeping for 5000 | 2007-06-19 22:24:43,556 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] TransactionReaper::check () | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4055795#...
