Im given a problem and am currently trying to come up with the best way to solve it. I have a few ideas, but one question about jboss clustering. keep in mind these applications were written very poorly, thats why they require so much memory and there is nothing i can do about that right now.
Now, I have clustered applications on Jboss where the application was small enough to run on one box. Meaning if i needed to, one machine could handle the load. But the current problem is that i have been asked to run several systems on the same environment. Our machines are virtuals and due to limited hardware, are restricted to 8 gigs of ram which gives jboss about 7 gigs to itself. That isn't enough to run the group of applications, Im constantly getting heap errors and crashes.
If i cluster 2 or 3 jboss instances together, can i run applications that consume more resources than a single box can handle?
