[jboss-user] [JBoss Cache: Core Edition] - Re: Cache modified time not updated in a clustered environme

[manik.surtani@jboss.com]

All eviction logic, queues and timers are local to a single cache instance and is not shared across a cluster.  Marking a node as in use, also, only affects a single cache instance.

Since you have your own eviction policy that actually does a remove instead of an evict, that's where you may have a problem.  Perhaps using your own RPC call across a cluster to have all caches call markNodeCurrentlyInUse()?  Why do you need a custom eviction policy that does a remove anyway, why not just a standard eviction policy?  If you don't use a cache loader it has almost the same effect as a remove, and won't affect the entire cluster.

Oh and FYI this API call is available in 1.4.X - you just need to get a hold of the TreeCache, not just the TreeCacheMBean, and call getEvictionRegionManager().
