Synchronize in Clustered Environment

[nitin pokhriyal]

Hi ,

Recently i came to encounter a situation where code works fine in single environment using synchornization block but now code has to move in clustered environment. I was wondering how can we prevent same thing in clustered environement. Any idea is appreciated.

Thanks

Go for terracotta

What terracota can do in this scenario? I think "Terracota" is a company with lot of products under its belt.

I wrongly marked this thread as a resolve but actually it is not. So can admin help here to reopen this thread or should i start new?

I flagged it as "unresolved".

The main Terracotta product does what you want -- don't know the name though (but it's not the ehcache product).

Basically, the product includes a class loader that will change synchronization calls to remote calls to a services that will do the synchronization. This allows multiple JVM to do synchronization together.

Obviously, you will pay a price -- as there is a big diff between a lock grab (in memory) and a network call and response to a service to do a lock grab. So, you definitely don't want to do this with every lock.
