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.

[U2] U2 Silliness from a vendor

We've been having performance problems as of late which have been tracked
down
to disk IO. When I was talking with our hardware vendor, he had one of his
Sun techs with him where we had the following exchange:
Sun tech: Because of the inherent difference of random and sequential you
want
to ensure your archive/redo logs are on a different mount then your
database
files.
Me: Oh - we're not on Oracle.
Sun tech: Whatever the database, you've got archive/redo logs.
If we're not using RFS, can someone confirm that Unidata really doesn't
have
archive/redo logs - or am I just clueless. I've been wrong before...
