    Periodic Recovery runs at every 2 minutes in jboss as 7.1 (com.arjuna.ats.arjuna)

    Ramesh Chokkapu Newbie

      Hi Gud mrng..

       

      please answer  for below  question anyone.

       

      Periodic Recovery is running in my jboss as 7 server at every 2 minutes. In that time my server working as 'stop the world'. after recovery completed then again its working normal... recovery taking too long time means ( between 30 secs and  120 secs).


      And i want to increase this 2 minutes to 10 minutes.. and where should i configure this time in my standalone xml...

      (or)

      how can i disable this Periodic Recovery?

       

      In standalone.xml :

       

      <subsystem xmlns="urn:jboss:domain:transactions:1.1">

                  <core-environment>

                      <process-id>

                          <uuid/>

                      </process-id>

                  </core-environment>

                  <recovery-environment socket-binding="txn-recovery-environment" status-socket-binding="txn-status-manager" recovery-listener="false"/>

                  <coordinator-environment default-timeout="300"/>

         </subsystem>

       

       

      and

      In Hibernate :

       

      cfg.setProperty("hibernate.transaction.factory_class","org.hibernate.transaction.JTATransactionFactory");

      cfg.setProperty("hibernate.transaction.jta.platform", "org.hibernate.service.jta.platform.internal.JBossAppServerJtaPlatform");

       

      In Ejb :

       

      Bean managed trasations. but i am not using any transations.

       

       

      how can i disable transation management in jboss as 7 or at  Ear Application level ?

          You can change the timeout using the default-timeout parameter in the coordinator-environment element.

           

          If your code is running from an EJB you can use the javax.ejb.AccessTimeout annotation instead. (EJBs are super easy these days so it's worth checking this out - an EJB can even be in your webapp if you want).

           

          But really, you should try to avoid these "stop the world" scenarios. If you tell us what you're trying to do maybe we can can come up with a better solution.

            Thank u very much for reply sir,

             

            <coordinator-environment default-timeout="300"/> (5 minutes). this already existed defaultly in my standalone.xml

            but PeroidicRecovery Running in every  2 minitues... where is that 2 minitues configuration in my server, i didnt get still..

            but i have checked in source code in com.arjuna.ats.arjuna.coordinator.TransactionReaper class

            In that code declared as "public static final long defaultCheckPeriod = 120000; // in milliseconds".

            i want to change this time.

             

            how can i achieve from this? i need this Recovery in every 1 hour..

            (or)

            how can i disable this Periodic Recovery Completely in my jboss as 7 server?

             

            please help me sir..

              I don't think the transaction recovery thread should cause "stop the world" problem. Have you taken thread dumps and did other diagnostics tests to see what's causing this "stop the world" problem? The recovery itself taking 30 to 120 seconds for each run looks wrong.

                I've moved this thread to the JBoss Transactions forum, at least for now, since someone from that team might have a better understanding of what's going on.

                    Hi Ramesh,

                     

                    If you look at your log in your original post periodic recovery is not taking anywhere near 30 seconds.

                    04:56:11,392 DEBUG [com.arjuna.ats.arjuna] (Periodic Recovery) PeriodicRecovery: background thread Status <== SCANNING

                    04:56:21,402 DEBUG [com.arjuna.ats.arjuna] (Periodic Recovery) PeriodicRecovery: background thread backing off

                     

                    Its taking 10 seconds, which corresponds nicely to the 10 second sleep which takes place between:

                    04:56:11,397 DEBUG [com.arjuna.ats.arjuna] (Periodic Recovery) 

                    04:56:21,398 DEBUG [com.arjuna.ats.arjuna] (Periodic Recovery) Periodic recovery second pass at Thu, 30 May 2013 04:56:21

                     

                    Overall this is not causing your "stop the world" problem, it may coincide with another event that happens then but as I see it recovery is doing almost nothing.

                     

                    If you want to change the values related to recovery intervals:

                    -DRecoveryEnvironmentBean.periodicRecoveryPeriod=<default is 120> -DRecoveryEnvironmentBean.recoveryBackoffPeriod=<default is 10>

                     

                    Hope that helps,

                    Tom

                      Thank u very much to Tom sir and all,

                       

                      -DRecoveryEnvironmentBean.periodicRecoveryPeriod was very helpful to me.. thank you alot..

                       

                      but

                       

                      please look at my log below TIME before "<== SCANNING"  and "after backing off" taking long time.. why it was taking that much time for SCANNING and backing off.

                        Hi Ramesh,

                         

                        I can confirm that the line immediately after the one that is printed is a sleep for "RecoveryEnvironmentBean.periodicRecoveryPeriod" seconds.

                         

                        I would therefore assume that there is some other activity in play that is causing the sleep. Why don't you get a few thread dumps imediately after:
