Thus, if you want to recover to <FONT color=#0000ff face=Arial size=2>a point in time for a multi-schema /one instance system, i<FONT color=#0000ff face=Arial size=2>f one schema gets rolled back - everything gets rolled back.

We had
this same issue.  Perhaps someone knows a way around this.

  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.

    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
