Gary Tully updated AMQ-1585:
----------------------------
Attachment: AMQ-1585.transacted.patch
with a transacted producer there is a failure, txid does not exist.
modifying the TransactedTopicMasterSlaveTest to stop the master reproduces the
problem. The fix is to have the failover transport state tracker rember the
transaction begin command so that the begin can be correctly replayed.

> -------------------
> Hi all,
> I am having trouble setting up a *stable* ActiveMQ Pure Master/Slave topology.
> Initially I have tried v4.1.1 which failed with an exception. I found an AMQ
> JIRA ticket which said that Pure/Master slave didn't work in v4.1.1.
> Ok, so I switched to AMQ 5.0.0, created 2 configs (master/slave, see end of
> message) and ran two AMQ instances (on the same box) and most of the times my
> test (see below) worked, but more often I get various error messages like:
> - On the slave:
> ERROR Service - Async error occurred:
> javax.jms.JMSException: Slave broker out of sync with master: Dispatched
> message (ID:tbuckel-desktop-41814-1202886136210-0:0:565:1:1) was not in the

> - After having killed the master, stopped the slave, copied the slave's data
> into the master's data directory various error message came up (as described
> in the Master/Slave recovery section), e.g. (internal) ActiveMQ topics were
> not available, the admin webApp showed exceptions and errors on the client.
> The test I've created uses Spring 2.0.x and pumps 1000 MapMessages in a queue
> through Spring's JmsTempate, each message is created within its own
> transaction, using JmsTransactionManager and TransactionTemplate.
> The created messages are consumed by an initially instantiated transactional
> DefaultMessageListenerContainer. The AMQ JARs in the test's classpath are
> activemq-core-5.0.0.jar, geronimo-jms_1.1_spec-1.0.jar,
> geronimo-jta_1.0.1B_spec-1.0.jar as I've noticed a really bad performance
> when only using the activemq-all-5.0.0.jar (maybe this is the problem?).
> The test code work's without problems with OpenMQ, but I'd prefer using the
> nice Pure Master/Active ActiveMQ if I can get it running in a *stable* config
> ;)
> I would highly appreciate any help or suggestions. Maybe my config is wrong
> or I miss something essential. I've also tried a recent AMQ 5.1 SNAPSHOT
> which wasn't better...
> See below for the small program i used to test (no unit test, behaviour
> appeared to be non deterministic to me and it's not so nice as i've changed
> it quite often)
> Thanks in advance,
