Windows Systems: Troubleshooting Symptom 3

Symptom: Instances of Agent for Sun Java System Web Server 6.1 are not effective after modification of the Sun Java System Web Server 6.1 configuration using the Administration Console

Possible Causes: The changes made by the agent installation to the server configuration files are overwritten by saving the changes in Administration Console.

Possible Solution: The right procedure when using the Administration Console is to load the configuration first (from disk file to memory), then to make modifications and save the changes (from memory to disk) by clicking the Apply button.

Windows Systems: Troubleshooting Symptom 4

Symptom:When a user attempts to access a resource using Internet Explorer as the browser, access is denied.

Possible Cause: Internet Explorer overrides the port number of the web agent with the Access Manager port number. In such cases, the agent log file lists the URL that is being evaluated. The port number for that URL is incorrect.

Possible Solution: You can ensure this problem does not occur by setting the following property in the web agent AMAgent.properties configuration file to true as shown:

com.sun.am.policy.agents.config.override_port = true

Windows Systems: Troubleshooting Symptom 5

Symptom: The agent issues a message stating that the web server is not recognized. This problem is specific to Agent for Sun Java System Web Server 6.1.

Possible Cause: Agent for Sun Java System Web Server 6.1 searches for the file WebServer.inf to verify the web server version number, but the file does not exist.

Possible Solution: Enable Agent for Sun Java System Web Server 6.1 to recognize the Sun Java System Web Server 6.1 instance by creating a file and adding text to that file that includes the version number of the Sun Java System Web Server instance as demonstrated in the task description that follows.

To Create a File To Allow Agent for Sun Java System Web Server 6.1 To Recognize the Web Server

Create a directory named WebServer in the following directory of the Sun Java System Web Server 6.1 instance:
```
WebServer-base/setup/
```
After you perform this step, the full path to this directory is as follows:
```
WebServer-base/setup/WebServer/
```

Create a filed named WebServer.inf in the WebServer directory.

After you perform this step, the full path to this file is as follows:
```
WebServer-base/setup/WebServer/WebServer.inf
```

Add the version information of Sun Java System Web Server 6.1 to the WebServer.inf file.

After you perform this step, the WebServer.inf file includes the following type of information:
[webcore] Version=6.1

Save the file.

Next Steps

Once you have properly created the WebServer.inf file, install Agent for Sun Java System Web Server 6.1.
