    Recovering non-serializable XAResource

    Juha Moisio Newbie

      Hi,

      We are using JBoss 4.0.5GA with JBossTS (jta) and Sonic JCA Adapter for JBoss to connect SonicMQ JMS Server.

      We have clustered sonic server and the JCA adapter is capable to reconnect another node when connection is dropped.

      Today we made a test where we crashed Sonic server during sending and receiving messages, one message was lost, and after that JBossTS
      started to log:

      21:58:33,137 WARN [loggerI18N] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] Could not find new XAResource to use for recovering non-serializable XAResource < 131075, 31, 29, 1--3f3db8c2:efb2:45d46e6d:113eb-3f3db8c2:efb2:45d46e6d:113ec >
      



      Server is still running and TS has been logging this several hours.
      I tried to google and read manuals but I did not figure out
      meaning of this warning. Could someone tell me what is going?

      Best regards,

      Juha Moisio

          Is the XAResource serializable?

            Hi Mark,


            Do you know if there is some way I can check it without asking from Sonic Software? Because I'm quite sure we are dealing with Sonic's XAResource...


            And if I guess right, it isn't serializable....

              I suspect it isn't serializable. In which case you need to read the Failure Recovery Guide and the JTA Programmers Guide and look at what they have to say about the Recovery Manager and the XAResourceRecovery interface. Then check out http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossTSRecovery.

                I just noticed, it also can be MySQL XAResource... is there any tool I can use to read files in JBossTS object store?

                  I'm just wondering if someone could provide good example
                  of RecoveryModule for non-serializable XAResource.

                    Have you worked through the recovery tests I pointed out?

                      Sorry no... I have been very busy with other projects.
                      I will check them when I've time.

                        Hi Mark,

                        I gor answer from Sonic Software. They said that Sonic's XAResource
                        is not serializable. Does that mean I have to write own RecoveryModule for it?

                        I know you told me to make those tests...
                        I still haven't had time do them :-(

                          Yes. Definitely look at those examples.

                            Ok. It good to know that I'm on right track :)
                            Thanks for your help (again).

                              Hi Mark!
                              S0d0 is in Paris this week at the IBM Conference so I am writing the implementation of XAResourceRecovery class. I have gone throe those examples and discussed the problem with Sonic Software. I still have some questions about jbossjta-properties.xml file.

                              Where in *properties.xml file I should insert the properties

                              com.arjuna.ats.jta.recovery.XAResourceRecoveryOracle=com.foo.barRecovery
                              and
                              com.arjuna.ats.jta.xaRecoveryNode

                              as said in jtaProgrammersGuide?

                              And what should be the value of xaRecoveryNode? How to know what kind of identifier JbossTs creates for the node?

                              Here is my jbossjta-properties.xml file. Properties in question are at the end of file.

                                I still have some questions about jbossjta-properties.xml file.

                                Where in *properties.xml file I should insert the properties

                                and
                                com.arjuna.ats.jta.xaRecoveryNode


                                As it says in the recovery examples on the wiki:

                                "You also need to add the following to the jta section of your properties file: "

                                Please check out the wiki examples before proceeding. They will help explain a lot of what is going on.


                                as said in jtaProgrammersGuide?

                                And what should be the value of xaRecoveryNode? How to know what kind of identifier JbossTs creates for the node?


                                It needs to be alphanumeric. All you need to do is make sure that the value is unique across your nodes. Some users simply start at "1" and work their way up.

                                  Hi Mark!

                                  It says following in the ProgrammersGuide


                                  Note: When running XA recovery it is necessary to tell JBossTS which types of Xid it can recover. Each Xid that JBossTS creates has a unique node identifier encoded within it and JBossTS will only recover transactions and states that match a specified node identifier. The node identifier to use should be provided to JBossTS via a property that starts with the name com.arjuna.ats.jta.xaRecoveryNode; multiple values may be provided. A value of ?*? will force JBossTS to recover (and possibly rollback) all transactions irrespective of their node identifier and should be used with caution.


                                  You said


                                  It needs to be alphanumeric. All you need to do is make sure that the value is unique across your nodes. Some users simply start at "1" and work their way up.


                                  As I have understand it JBossTS handles the creation of that identifier. I am only trying to implement XAResourceRecovery for non-serializable XAResource. So can I use

                                  <property name="com.arjuna.ats.jta.xaRecoveryNode" value="*"/>
                                  


                                  in jbossjta-properties.xml file even thou it says


                                  A value of ?*? will force JBossTS to recover (and possibly rollback) all transactions irrespective of their node identifier and should be used with caution.

                                    If you check out the JTA guides that ship with the product, you will see reference to com.arjuna.ats.arjuna.xa.nodeIdentifier. This needs to be unique for each node in your environment. xaRecoveryNode tells the recovery subsystem which nodeIdentifiers is should perform recovery on and which it should ignore. * is a wildcard.
