In my experience with Linux Oracle, it supports all the standard Oracle
functions, replication, hot standby, etc.  To me a gfs situation with
Oracle would be an ideal situation.  Put Oracle data files on the shared
array and just start oracle on the standby machine if the primary fails,
although there amy be something with Oracle that wouldn't allow this.

I've seen Oracle run in hot standby mode with Linux, but in this mode it
requires you to eventually rebuild and repopulate the standby server, or
you can go back and forth, the standby because the primary and the
original primary then becomes the standby.

I also think there something with Oracle 8i that allows the standby to be
mounted in read only mode which makes things easier when restoring the

I just throwing things out from past experience, I didn't actually do any
of the stup of this, I'm not a DBA.
