1. Re: Lock durations and catchEvent() callback events
mircea.markus Mar 3, 2010 4:07 AM (in response to teroheinonen)Q1: in case the local node makes the put-operation, how do the locks behave with respect to:
- catchEvent() callback when e.isPre() == true
- catchEvent() callback when e.isPre() == false
Are the acquired locks locked during both callback call events? Or during any of them?
yes, the current thread (or tx associated with it) does have the locks (locked) during both calls.
Q2: as above, but in case some other node makes the put-operation (which is also currently partitioned to the node in question)
let's say that we have A, B nodes and k1 the key to be updated, residing on B (and backuped on some other node C, numOwners=2).
On A: cache.put(k1, "val1"); //this will call a local event listener, with lock held on k1
then, when distribution will update the remote value on B, another listener will be called in B's JVM, again, with locks held.
