"Everybody wants to go to heaven, nobody wants to die" - 24x7 operations

Greetings All,

My company is running a large manufacturing application (Glovia) on a RS/6000 S70 using Oracle 7.3.4. The manufacturing plants don't ever want the database to come down (well, hardly ever - "everybody wants to go to heaven, nobody wants to die"). The S70 has mucho disks, at least a couple of SSA arrays with 4.5GB disks. Right now, the database is currently in NOARCHIVELOG mode; I've had many a long argument regarding this. The database is shut down for about 2 hours (as much as 6 if the users won't get off) for a system backup to be taken using the AIX 'sysback' utility.

I've FINALLY gotten through to them about the requirement to run in ARCHIVELOGMODE - the options being considered are:

(a) Triple Mirroring with Hot Tablespace Backups
(b) Hot tablespace backups without mirroring

I've seen a white paper by Oracle that briefly describes the triple mirroring, but I was wondering if anyone out there has ever eimplemented it, or if anyone has any alternatives. Thank you very much.
