RE: [U2] U2 Silliness from a vendor
Unless you are running RFS, no, there are not any. However if you are they should be on a separate mount. Some may think you need them but from my experience the database is so robust it has never been necessary. Of course I've never run the database on MS.

RE: [U2] U2 Silliness from a vendor
We have a similar scenario on UV/AIX. Our unix tech was actually a bit more detailed. They're talking about the unix filesystem logs - in our case, JFS/JFS2 logs. If they're isolated to a different logical partition, the system is a little more efficient. I'm not sure if that applies to your system or not, but it sounds like the same 'tech suggestion'. Hope this helps!

Re: [U2] U2 Silliness from a vendor
correct. If you don't have Recoverable File System (RFS) enabled, there are no archive/undo/redo logs for UniData. Of course - virtually all UniData data file i/o is essentially random i/o. You should tune your disk subsystem to accomodate this. Wally Terhune SWG Client Support - Information Management Software U2 Support Architect b IBM U2 Client Support Team 4700 S.
