hi all,
My company is asked to make a proposal for an ERP application for
several small business companies who uses this application.
the situation now is that those companies each have a single database
(9.2.0.8) on the same node.
In the new situation it will be be 1 or 2 10G release 2 RAC Clusters
with each one " shared" database. Oracle Label security must assure that
on row level the different companies can not use each other's data.
I am examining three questions:
- is Oracle Label Security an absolute, garantueed, method that
different companies using the same database/schema, not can see each
others data? My company has as far as i know no experience met Label
Security, so therefore is ask here for experiences;
- is there any argument for two clusters above one clusters with 2/3/4/n
instances?; i don't see them, concerning avalaibility, scalablity, or
other, but maybe i overlook something;
- can i use the the "services" concept in 10G RAC to force a bit of a
flexible way of loadbalancing (company A and B uses instance 1, coampany
C and D uses instance 2, company Eand F uses instance 3, etc.. and
flexible, that i can change that when company C uses more resources at
moment x...
Thanks,
Joop Gijsbers
