I wonder if it's possible to invoke a method on all instances of a MBean of a cluster?
Not as far as i know, but you could lookup a cluster view via haPartition and loop through the server nodes and call the methods manually.
It's a bit more work and probably not the fastest possibility but should do it.
Somethuing different just came in my mind, what if you install listeners on every node and broadcast a message to all of them?
