Two instances same home, how to restrict access of client from certain IP's?
I have 11gr2 rac on two nodes(say the DB SID is PRD), I also created a new instance (STG) on one of the two nodes in same home. Now I need to have access control so some client can only access STG instead of PRD. What is the best way? I know I can create login trigger to check IP address but feel it is not best.
Thanks
