    XA recovery in JBossMQ

    Paul Robinson Master

      Hello,

      I noticed on the JBossTS forum the following posting:

      http://www.jboss.com/index.html?module=bb&op=viewtopic&t=83316

      This posting is off-topic in the JBossTS forum and as such won't get a response.

      I would also like an answer to this query, can we discuss it here please?

      Thanks,

      Paul.

          To make things easier, here is the origional posting:

          In order to get proper crash recovery, I was advised to use JBoss Transactions in place of the built in JBoss transaction manager. But a colleague pointed out to me that the recover() method in SpyXAResource.java returns an empty list of xids.

          public Xid[] recover(int arg1) throws XAException
          {
          if (log.isTraceEnabled())
          log.trace("Recover arg1=" + arg1 + " " + this);

          return new Xid[0];
          }

          Doesn't this mean that MQ will forget about any transactions that were left in the prepared state when a crash occurs? Will JBoss Transactions buy me anything. Our transactions span MQ (backed by Oracle) and Hibernate (also backed by Oracle).

          Thanks

            Unfortunately the original post is not very useful without the response(s) that followed. Interested parties should read all of the original thread.
