Hello,
I know that this was part of a previous thread, but the thread didn;t cover the database integrity.
Somebody asked if you should use cooked or raw devices with Oracle, for speed and integrity reasons.
From what I know, If you use cooked devices on unix, the file system will try to cache as much as it can and the data you commit will be "commited" in the fs cache and flushed from time to time to disk. This means that if the server crashes you will probably loose non-flushed data with the database engine not being aware of the loss(so no rollback for you).
Am I wrong, is Oracle smart enough to detect this situation? Thanks
