Global lock question

[hsaha]

Hi,
Is there any way to obtain a lock on a node for a cluster?
Ideally for a distributed global cache, i may want to lock a particular node for update. Is there a way to use the org.jboss.cache.lock package or any alternatives?

I understand that in 2 phase commit, the write-lock is obtained on transaction commit, but i would like to lock a node for update, then perform the update so that the changes are reflected globally.

An example for that could be global statistics in a cluster.

No, there is no way to acquire and hold distributed locks. The 2PC mechanism is how we ensure data consistency across the cluster.

Thanks Manik.

Just curious.. are there any plans for this feature in future releases or this use-case is not considered at all at JBoss.

Sorry Himadri, no such plans at this time.
