Home -> Community -> Mailing Lists -> Oracle-L -> Re:Oracle and MC/Serviceguard
Riley,
Having done this a couple of years ago:
Put EVERYTHING on the shared disks. The major reason for this is that any temporary files created by our good friend Oracle to detect what has happen will be in $ORACLE_HOME/dbs by default. Failure to do so may cause your db to act very funny if not start up at all when the system switches over. In general you want the file systems to look identical in all respects when each machine is running as the 'prime host'. Now, as to your suggestion about upgrading, don't. The reason is that you have to take the db down one way or the other to upgrade and it's a lot better to do it once than to forget you did not upgrade the backup host.

We are implementing MC/Serviceguard here for failover, and I have some questions about configuration/placement of Oracle files.
Our Oracle environment:
Oracle 8.1.6 (64-bit)
HP-UX 11.0 (64-bit)
We are not running OPS. The shared disks are on HP AutoRaid.
Do all Oracle files need to be on the shared disks? I know that the datafiles for all data/index/rbs tablespaces need to be there, as well as the control files and online redo logs. How about datafiles for temp tablespaces or archive logs? One other thing: would it be possible to have the Oracle binaries *not* be on shared disks, so that for Oracle upgrades/patches we could failover, upgrade/patch Oracle on the primary host, then fail back to the primary and upgrade/patch Oracle on the backup host?
Thanks in advance!
Riley
