Indicating a time out from lack of connectivity somewhere along the chain of communications (firewalls, permissions, etc.)

Would recommend using ODP.NET instead of OLEDB for web service efforts

Please see this solution

 

ODP.NET, Managed Driver supports connecting to Oracle DB server 10.2 or higher. It does not support DB 10.1.
