    SuspectException handling.

    Thomas Jean Newbie

      Hello,

      i'm working on a two nodes synchronous replication cluster.

      I make a failure happen (with System.exit()) on a node when performing an operation on memory with the other node in order to check failover capacities.

      All my operations are in transactions with dummyTransactionManager.

      Then when node crash, the other node throws the SuspectException. ==> This implies that when a node crash, all in progress write operations from other nodes will fail?

       

      See StackTrace:

      My question is can we handle this exception to retry the failed operation?

      Is the cluster still coherent if we do so?

      Is this problem handled in next versions of infiniSpan?

       

      Have a nice day,

      Thomas.

          Well it depends on how quickly the suspect is removed from the cluster and a new view is installed.  This is controlled by your failure detection settings in JGroups: FDVersusFD_SOCK

            Manik, I can not open the link that was put into the prior post you did.

              Ok, thanks for yours replies.

              I saw the document for failure detection but i don't see a way to speed up the view replacing.

              I give you a more detailled log view to analyse the problem

              (See StackTrace at the bottom)

              (You can see the config file too at bottom.)

               

              On this stackTrace, we can notice that the Exception happen 125 ms (14:25:51,847 - 14:25:51,722) after trying to put() and remove() variable in cache. ==> It makes me suppose that it is not a timeout problem..

              The problem appear to be in the short period between:

              1. FD_SOCK     - VIEW_CHANGE  received:  [ProcessUnit_AgentManager_1-2202]
              2. AbstractLogImpl     - Received  new cluster view:  [ProcessUnit_AgentManager_1-2202|6]  [ProcessUnit_AgentManager_1-2202]

              I suspect there is short period of time where the cluster state is not coherent and it should be managed to prevent request to fail by waiting that the new view will be replaced.

              Can you confirm or invalidate this hypothesis?

               

              Have a nice day,

              Thomas.

                If you invoke an RPC on {A,B,C,D} and C fails, then the RPC will be received by A, B and D, but because C failed there's a suspect exception.

                 

                If you want atomicity, ie. A, B and D should *not* apply the change, then you need to make the call in a transaction.

                  Call in a transaction and configure a JBoss Transactions based transaction manager lookup instead of the dummy transaction manager. The former is a fully fledged transaction manager whereas the second is purely for dummy testing.

                    Hello everybody, thanks for your replies that help me in managing suspectException.

                     

                    I resolved the problem by using the jbossjta transactionManager, then  catching the suspect exception, waiting for view to change, then rollbacking the transaction and retrying the operation.

                     

                    But i come back with a new problem on SuspectException Handling.

                    I recently upgrade ISPN to version 4.1.

                    I did notice that SuspectException was catched at ISPN level which was throwing a RollBackException which trace is :

                    javax.transaction.RollbackException: [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted][com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] Could not commit transaction.

                     

                    Well, i adapt my code to simply retry operation. But it seems that locks are not released.

                    Let's see the trace:

                    Manager 51908 ERROR 14 sept. 2010 17:09:56,874 [Session Task] interceptors.InvocationContextInterceptor     - Execution error:org.infinispan.util.concurrent.TimeoutException: Unable to acquire lock after [20 seconds] on key [test2.msgState] for requestor [GlobalTransaction:<node01-26609>:5]! Lock held by [GlobalTransaction:<node01-26609>:4]

                     

                    All futur attempts to acquire lock will fail in the same way until process is restarted.

                     

                    Is anyone experimented the same problem?

                    Have a nice day,

                    Thomas.
