ORA-24778: cannot open connections

2968123Jun 9 2017 — edited Jun 9 2017

I am getting error 'ORA-24778: cannot open connections' when a front end screen tries to connect to database B via a shared db link in database A. What are the possible causes?

the DB link is a public shared link. We tried bumping up the db parameter open_link_per_instance to 40 and bouncing the database. The error stopped for a while only to re-appear again.

DB : oracle 11g

J2EE application running on Weblogic 10

Please help!
