HAJMS fail over problem

gokturk Apr 1, 2004 1:38 PM

I am trying to use HAJMS to achieve fault tolerance, I think I stumbled into a bug. Messageid seems to be kept in memory separately in each server in the cluster. If there are persistent messages stored into database and waiting to be consumed, trying to fail over to other server causes database to throw unique constraint exception on messageid. I think max(messageid) needs to be taken from persistent store during fail over to avoid this problem.

Which JBoss version?
If it is 3.2.3, then you may want to get the 3.2.4RC since it has significant enhancements.

Ivelin, I am using 4.0.0DR3, not sure it has the same enhancements?

It does not. It is not in 3.2.4RC1 either.

You have to get it from cvs
cvs ... co -r Branch_3_2 jboss-3.2
then run the all configuration.

HAJMS from 3.2.4 is not synced up with 4.0. Interested to help?

Thanks for the responses... Ivelin, for your question for the help, yes but after I get more familiar with jboss...
