In 8.1.x, as long as your schemas have their own tablespaces, you could to TSPITR (Tablespace Point in Time Recovery).

Please respond
to ORACLE-L
Something to ponder. The archive logs are tied to the system. Thus, if you want to recover to a point in time for a multi-schema /one instance system, if one schema gets rolled back - everything gets rolled back.
We had this same issue. Perhaps someone knows a way around this.

1. Is that performance gain absolutely necessary?
What happens if one company goes down and takes down them all.
On another note, I tend to agree on lesser instances against more
instances. Easier to tune, better perforamance due to what I call
instance wastage and much easier to maintain. But if one system
changes alot, has significiantly different access methods, or goes up
and down more than anyone, I would evaluate seperate instances.

Subject: Multiple schema's or multiple databases
Oracle 8.1.6 and Solaris
I'm going to inherit production databases when I start my new job
next week. I gather that the production database consists of 8
schema's (8 companies) that are all in one database. Its an ERP
package called Maximo and it interfaces to Financials 11i
databases (don't know if this is multiple databases or schema's
yet).
Apparently there is some data passing between companies and
multiple schema's perform better than using database links with
multiple databases, and this is the reason for multiple schema's.
Does anyone have an opinion on this. If I'd have done it I would
have done multiple databases as they are separate companies, but
I'm open to comments as not quite got my head round it yet, plus
I've been vacationing (partying) for 3 weeks.
Thanx
Sam
