    Pessimistic Locking

    Nathan Messer Newbie

      I'm not sure my understanding of pessimistic locking is correct, as I have a situation which is working but I don't understand why.

      My understanding is that:
      1) Locks are held for the duration of a transaction
      2) Writers must wait until there are no read locks on a node

      I have a transaction T1, which reads a node A from the cache, so it should have a read lock on the node.

      This transaction is then suspended, when an EJB method is called with it's transaction attribute set to requiresNew. This transaction T2 then writes to the node.

      Transaction T2 then commits, and transaction T1 continues, and commits as well.

      I'm using Pessimistic Locking with an Isolation Level of READ_COMMITTED

      Why does T1s read lock not block T2s obtaining of the write lock?

          Have you got PessimisticLockingInterceptor logs to show this behaviour? To check lock owners, etc. of the data being accessed?

            I've turned trace logging on for

            org.jboss.cache.interceptors.PessimisticLockInterceptor

            but all it gave me was the following.

            I'm trying to get more comprehensive logs for you, but it's proving difficult to get the app up with a lot of trace logging turned on.

                  Forgot to mention, the interesting part is the locking of the node /Parameters/ISchmParam/4686570 in GlobalTransaction::42 and GlobalTransaction::43

                  • 6. Re: Pessimistic Locking
                    Mircea Markus Master

                    The logs you sent do not show how GlobalTransaction::43 tries to acquire locks on /Parameters/ISchmParam/4686570, only how to first one succeeds. They seem incomplete.
                    Is it possible for you to do the following:
                    log this : CachePrinter.printCacheLockingInfo(c) immediately after suspending the first tx and immediately before committing the second one?
                    Also, can I have the full jbosscache log (full meaning everything logged by org.jboss.cache in time frame before starting the first tx and after the second one successfully commits.

                      You are quite correct, I seem to have lost some of the log while pasting into the forum.

                      I'm reposting the relevant section here.

                      I'll also try and get you the full log you asked for, it may take me a little while though, as it takes quite a long time to get to that point with much trace logging turned on. Is it trace level logging you need?

                        I have a transaction T1, which reads a node A from the cache, so it should have a read lock on the node.

                        This transaction is then suspended, when an EJB method is called with it's transaction attribute set to requiresNew. This transaction T2 then writes to the node.

                        Transaction T2 then commits, and transaction T1 continues, and commits as well.

                        I'm using Pessimistic Locking with an Isolation Level of READ_COMMITTED

                        Why does T1s read lock not block T2s obtaining of the write lock?


                        The semantic you described sounds like REPEATABLE_READ to me, not READ_COMMITTED.
