Kevin, I heard your name before and I am fully aware that you know much more then me. Truly symmetric clustered FS that I used to work with was known as Files-11. DEC representative used to tell us, I quote, "not to do image activation from remote nodes". As you probably know, VMS did not do file caching before version 6. The only question I have is synchronization of caches across the nodes. [snip] -- http://www.freelists.org/webpage/oracle-l
