"The Network Adapter could not establish the connection" error
903917Jun 21 2012 — edited Jun 26 2012I'm intermittently able to connect into my development database from my PC. When I'm not able to connect in, I'm getting a message of "The Network Adapter could not establish the connection" regardless of the client I'm connecting with. This database is located on a server and is Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production. I have a local install of WebLogic Server that has generated the error message when attempting to start. I have also received the message in SQL Developer and SQL Plus.
As I stated in my first sentence, the issue is intermittent this morning - sometimes I can connect and sometimes I can't...
I've been working successfully in this database for months now without this issue, so I'm guessing that the database itself is having issues, but I'm not a DBA...just a measly developer trying to use the database ;)
Are there good questions for me to ask of my DBA or ways to discover what could be causing the issue? Or, is there something I can do on my machine to get around this?
