Hello.
I'm evaluating JBoss Messaging 2.0.0 BETA4 .
And, I tried the following procedure to check JBM's persistence functionality.
1. Start up JBM.
2. Check MessageCount of ExampleQue by jconsole. and 0 message found.
3. Producer sends a hundred messages to ExampleQue by a single transaction. and commit.
4. Check MessageCount of ExampleQue by jconsole. and 100 messages found.
5. Kill JBM process by Windows Taskmanager.
6. Start up JBM again.
7. Check MessageCount of ExampleQue by jconsole. and 100 messages found. It's OK.
...and I tried once more.
9. Procducer sends a hundred messages to ExampleQue by a single transaction. and commit.
10. Check MessageCount of ExampleQue by jconsole. and 200s message found.
11. Kill JBM process by Windows Taskmanager.
12. Start up JBM again.
13. Check MessageCount of ExampleQue by jconsole. and only 105s message found!
My 95 messages have gone somewhere. persistence functionality does not seem to work
properly.
I confirmed following by jconsole.
o JournalSyncTransactional is true.
o ExampleQueie is durable.
o DLQ and ExpilyQueue has no message. (MessageAdded, MessageCound are 0)
And my environment is
o Windows XP SP3
o Sun JDK 1.6.0_15
o JBoss Messaging 2.0.0 BETA4
Any comments or suggestion?
