SCAN is not working, when connecting to DB from applications

880047Sep 14 2011 — edited Oct 1 2011

Hi ALL,

I am in big trouble, I am working on 11gR2 4 node RAC database, and 1hr ago i have bounce the database for some issue. It came up and working fine for me, when i am connecting from the server. but the users (Performance team) who are connecting from application, it is not able to connect with SCAN address. we haven't changed any thing at the DB level or at OS level. and even i is not connecting from SQLDeveloper. It is thronging error message saying that "IO Exception: The network adopter could not establish the connection"

What are the things i need to check, Please give me your valuable suggestions and all of the application team is waiting for this issue to be resolved.

Thanks in advance.
