Hi Amir,
This is a common practice. There is no need to create a new OS user. You can
even create a new database under the same Oracle home.
The thing to keep in mind is that the combination of ORACLE_SID and ORACLE_HOME
need to be unique. So, that will uniquely identify an instance on a host, and
then that instance's pfile/spfile will point to your database's control
file(s). In that way, your new instance will clearly identify which database
it will mount and open.
Hope that helps,
-Mark

Subject: Multiple Instance in Unix
Hi listers,
I have a HP Unix box that has Oracle 10g R2 installed on it. There is already
an instance running and a database attached to it.
I need to create another instance and database. There is no X Server installed
on the OS. I created the first database through command line.
My question is whether I have to create another OS user in order to create the
new instance? Or I can use the same OS user (oracle:dba) to create the new
instance? As I need to set environment variables then if I use the same OS
user, what would happen to the first instance?
Is there a guideline on how to do this?
Thanks.
