[JBoss JIRA] Created: (JGRP-297) Use deadlock detection (JDK 5) to find deadlocks in stress tests or during regular operation

by Bela Ban (JIRA)

Use deadlock detection (JDK 5) to find deadlocks in stress tests or during regular operation -------------------------------------------------------------------------------------------- Key: JGRP-297 URL: http://jira.jboss.com/jira/browse/JGRP-297 Project: JGroups Issue Type: Feature Request Affects Versions: 2.4 Reporter: Bela Ban Assigned To: Bela Ban Fix For: 2.5 The java.lang.management.ThreadMXBean has a method to check for and (if found) enumerate deadlocked threads (only with simply synchronized locks, jav.util.concurrent locks currently not supported afaik). This can be run every N seconds, and is useful in both stress testing and possibly also during operation. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1330) Using RuleBase in multithread application server environment

by Navaljit Bhasin (JIRA)

Using RuleBase in multithread application server environment ------------------------------------------------------------ Key: JBRULES-1330 URL: http://jira.jboss.com/jira/browse/JBRULES-1330 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: Rule Flow Affects Versions: 4.0.3 Environment: Red Hat Linux as OS, weblogic 9.2 using jrockit-1.5.0_10 Reporter: Navaljit Bhasin We are deploying an applcation which has one major component which executes rules. At the startup of the application server, we load the various rules and save them in a hashmap with appropriate key. The value of these HashMaps is RuleBase. This is part of a singleton service. The applcation is based on JMS. A MDB receives message, calls the sigleton service to get stateful session from a specific RuleBase ( saved in HashMap by key as mentioned above). This singleton service get the RuleBase from Map, call newStatefulSession(false) on this RuleBase object and return the new StatefulSession. This works fine as long as we have one MDB on the application server. When we increase the number of MDB's to more than one, and both MDB's process the messages( different messages) simultaneously, the results from stateful session rule firing are messed up. It skips amny valid LHS and so on. I even tried using the Stateless Session, but the results are still messed up. So my question is: Can we use the Rulebase in multithreaded environment ? My understanding was that we can use it. There should be no interaction between various stateful sessions received from same rulebase object. If we can't use it this way, the we have build it form PackageBuilder for every invocation. There are lots of complex rules and for hundreds of calls it adds up to considerable waste of resources. Thanks for reading this bug report Can you please post or email me the code to use the statefule sessions from a RuleBase object in multithreaded environment? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBMESSAGING-876) Allow onMessage to be executed on the remoting thread

by Tim Fox (JIRA)

Allow onMessage to be executed on the remoting thread ----------------------------------------------------- Key: JBMESSAGING-876 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-876 Project: JBoss Messaging Issue Type: Sub-task Reporter: Tim Fox Assigned To: Tim Fox Fix For: 1.2.1 As an optimisation we should allow message listeners to be executed straight through using the same thread that delivers the message to the message callback handler. This would avoid an extra context switch.. Currently the thread used is from an executor per session - so as to be strictly JMS compliant. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

Acknowledge in single tx optimisation ------------------------------------- Key: JBMESSAGING-1143 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-1143 Project: JBoss Messaging Issue Type: Task Reporter: Tim Fox Assigned To: Tim Fox Fix For: 2.0.0 Beta Current for client_ack or dups_ok we acknowledge each message in the list in a separate jdbc tx when persistent - this can be done in a single tx Furthermore, no need to send the complete list of ids to acknowledge - they will be contiguent - and can be worked out from the delivery list in the session. For a transacted session the same applies. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
