[jboss-user] [Clustering/JBoss] - Re: Singleton Failover

[chanyungwan]

There are totally 3 singletons.  Make it simple, may be we use 1 singleton to illustrate the scenario.  What I mean the "long" time for launching it in 2nd case is that the singleton almost needs 2 - 3 minutes for being completion of running its constructor and "startSingleton" method defined in jboss-service.xml, then finally the new cluster view is built.  You can see the following log in 2nd node once I quit the master node using "Ctrl-C":

:

Since there are 3 singletons in my case, so the total time for "completing" their activation is about 10 minutes.  It's really a big problem for us!!
