RE: two instance -- one database

Not exactly the same issue, but when we moved our application onto a
Citrix farm separated from the database server by a Gig Ethernet, then
some queries which had simply performed poorly when the were on PCs on a
10 meg Ethernet network suddenly had a significantly larger impact on
the database.

 

Obviously if the 2 databases are on separate servers there would be a
throttling effect on queries that involved full table scans of large
tables.

 

However I suspect that there would be a more conventional way to achieve
the same goal.

Subject: two instance -- one database

 

I have a friend (no really, this isn't some lame way of telling you
about me but trying to hide that by ... )

 

 

I have a friend, and at his company they have an Oracle database with
tables and data. We'll call it Database A and they have another Database
B that has views across dblinks to each of the tables in Database A. The
data team says that this protects Database A from bad queries.

 

So can anyone think of any possible benefit from this arrangement? Will
administration be easier, queries faster, performance more predictable?
Anything?
