I would like to limit number of connections through db link to one connection only.
I've set both parameters open_links and open_links_per_instance to 1.
But i can still run more than one queries in different sessions (also query inside pl/sql loop). What is wrong. I think that i can't understand these parameters meaning.
How can i limit number of connections through db links ? How these parameters work really what i don't know ? Very appreciate for any answer
