Oracle server error while connecting at localhost


At first you should check the doc ID 1311489.1

The doc solutions will be:

Configure a Network Channel
1.Configure a network channel for localhost [WebLogic Admin console > log in as Administrator].
2. Servers > Protocols > Channels.
3.Click on "Configure a new Network Channel,"
4.Configure the network channel as follows. [You may change the name of the channel]

 ◦Name: Loopback
◦Protocol: t3
◦Listen Address: localhost
◦Listen Port: 7001 [same as Admin server host]

Create the network channel.
5. Shut down and restart the server.
6.Look in the WebLogic log for a successful ping message:

<Mar 29, 2011 6:14:01 PM EDT> <Notice> <WebLogicServer> <BEA-000355> <Thread "ListenThread.Loopback" listening on port 7001, ip address>

Configure WLS 8.1 For Default

NOTE: This is for WLS 8.1 only.

You may take a test by doing:

1.In the console, navigate to <server> -> Configuration -> General -> Listen Address.
2.Remove any entry for parameter "Listen Address."
3.Apply changes.
4.Restart the WebLogic instance.

Now you can access the application with all DNS names/IP addresses which are associated with the machine. You can also use the loopback address for the weblogic.Admin PING utility. The WebLogic instance will listen on loopback address – either localhost or
