"alllle" wrote : | - What is considered as a "read"? I mean, does cache.getNode() considered a "read", or only when I do a subsequent node.get("key") is when the lock obtained? | cache.getNode() is a read. "alllle" wrote : | - With "REPEATABLE_READ" isolation, is the "write skew" still a problem? - I think it's not but I'd like to get a confirmation from you. | Write skews are *only* a problem with R_R. See the discussion in the user guide for details. "alllle" wrote : | - What is the scope of the current "InvocationContext"? Is it within the current transaction, or current thread, or something else? | Invocation contexts last for, well, an invocation! :-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4256831#...
