[jboss-user] [JBoss Messaging] - Re: problem when testing multiple failovers in a cluster

[chatzi]

Hi

Thanks for the reply.

Initially I did the following (all locally on my machine, Windows XP, SQLServer 2005).
1) Start the Cluster.
2) Wait for it to completely come up.
3) Start my 'test' tool
- The test simply sends messages as quickly as possible to a distributed topic, while additionally (in another thread) receiving them again.
- At this point in time both JBoss instances start consuming CPU.
4) Shutdown one JBoss instance (through CTRL-C in its command window).
- There are now some exceptions thrown in the background, but the test continues to run.
- There is no 're-initialisation' of any JMS recources whatsoever from my side (the cluster should be transparent to me).
5) Wait for 'my' test to finish.
- The test in the end reports the number of 'send' and received messages. Some have gone lost, but ok, not too many.

Now I did the test again,with the following differences:
1) Extend the duration of the test.
2) Start everything again.
3) Shutdown JBoss instance 'A' (as above)
4) Re-start JBoss instance 'A'
5) Wait for it to come up again.
6) Shutdown JBoss instance 'B'
- THE PROBLEM: At this point in time exceptions start to pour in, the test fails. 'Failover', i.e. the sender connection previously using 'B' now using 'A' did not happen for me.

Regards
Alex
