synch ehcache instance
hi guys
I have 3 application servers connected in cluster. each server has its own JVM. There is ehcache instance attached with each jvm. How will i make sure that each ehcache instance is in synch with other ehcache instance(s).
thanks

no it isn't
You can use jboss treecache

I have a ehcahce setup in my application, right now it just caches data. Is there anyway i can save the ehcache data in database?
thanks
thanks
Doesn't really make sense to do that.
You've stored it in the cache to *avoid* calling the database.

Depending on the data you may be able to solve it by giving the data a short lifetime. That way they may get a little out of sync but not for long before they get themselves back in sync.

from this documentation http://ehcache.org/documentation/distributed_caching.html
>>>A distributed or replicated cache eliminates the per-instance overhead of loading and refreshing multiple caches from a database.
which arises the question how is ehcache and database connected?

is the ehcache instance running on a jvm?..thx
its just a set of classes, it doesn't run seperately.
ie. the cache is part of your application

After reading the doc, i see there are two ways, one is through distributed using terracotta like you said which is not oen source and another way is using replicated mechanism. If i want to use the JMS replicated mechanism to keep instances in synch, do i have to buy any product from ehcache?
thanks
thanks
I think replication is available but 100% sure

Java
Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
