WebLogic Server Connection Refused


This is a simple symptom-cause-solution blog entry only. I hope these blogs will help fellow administrators.

Symptom

The WebLogic admin or managed server is running, but telnetting to it fails, with an error like:
Trying 10.123.123.123...
telnet: connect to address 10.123.123.123: Connection refused
Cause

You may be using a development/limited license. These restrict WebLogic to accept connections from up to 5 different IP addresses and then stop accepting connections from any other IP.

If you have multiple interfaces on the server, WebLogic may be listening on one of the others. If you do not specify a listen address for a admin or managed server, it will listen on all interfaces.

Solution

Replace the dev license with a purchased one, or restart the server to clear the 5 IPs that it accepts connection from.

Change the listen address, or telnet to the correct address.

Connection refused: No available router to destination

This is a simple symptom-cause-solution blog entry only. I hope these blogs will help fellow administrators.
Symptom

The following exception occurs in WebLogic server logs. Most likely to occur during WebLogic server start-up, but similar exceptions may occur at other times.

BAD_CERTIFICATE - A corrupt or unuseable certificate...

This is a simple symptom-cause-solution blog entry only. I hope these blogs will help fellow administrators.
Symptom
In wls_utc, when trying to test a webservice using SSL, the following error message is received: javax.net.ssl.SSLKeyException: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was received.
If SSL debugging is enabled, the following error also appears in the logs: ExecuteThread: '4' for queue: 'weblogic.kernel.Default (self-tuning)' <1254822672320>>
verification failed because RSA key public exponent [3] is too small
Cause
The certificate encryption is of a weaker strength than expected by newer versions of Java.
Solution
Add the flag "-Dweblogic.security.SSL.allowSmallRSAExponent=true" to the server startup parameters.

WebLogic Admin Console

WebLogic Admin Console
The WebLogic Admin Console is a web-based, user interface used to configure and control a set of WebLogic servers or clusters (i.e. a "domain"). In any logical group of WebLogic servers there must exist one admin server, which hosts the WebLogic Admin Console application and manages the associated configuration files.
WebLogic Administrators will use the Administration Console for a number of tasks, including:
Starting and stopping WebLogic servers or entire clusters.Configuring server parameters, security, database connections and deployed applications.Viewing server status, health and metrics. Note: It is not strictly necessary to use the Weblogic Admin Console to perform these tasks, as they can be scripted using WLST (the WebLogic Scripting Tool).
Accessing the Admin Console
WebLogic Admin Console Url: http://hostname:port/console.
To access the WebLogic Administration Console, assuming the admin server has been started, goto the above url. Where hostname…
