Problem(Abstract) |
When trying to access the Administration Console, the
browser displays "Error 500: An error occurred while processing
request." |
|
|
|
Cause |
This error can occur in a couple of different ways:
- After entering your username and trying to log in, the Error 500
message displays along with part of the Administration Console.
- You can log into the Administration Console fine, but after making
certain selections on the
left hand navigational menu in the Administration Console, the right hand
side displays the Error 500 message.
Both of these scenarios have been resolved on numerous occasions by one of
the following: |

Resolving the
problem |
First, be sure that the machine's hostname does not
contain an underscore. PQ75492 addresses this issue as underscores in
hostnames are not allowed. If it does not, then try the following:
- Logout of the Administration Console (if possible).
- Stop the server.
- Delete all contents in the
<install_root>/wstemp/
folder.
- Restart the server.
- Login to the Administration Console and see if the error
persists.
If cleaning up the wstemp folder does not work, follow these steps:
- Open up your web browser and delete all cookies, history, temporary
internet files, and so on. In Internet Explorer, select Tools >
Internet Options from the menu.
- Close and then reopen the browser.
- Access the Administration Console.
- Log in and see if the error persists.
- Navigate to <WAS_HOME>/config/.repository. There should
only be one file in this directory, metadata.xml. If there are
other files besides metadata.xml, problems can arise as WebSphere
tries to parse each one.
Note: In Version 6.0, the files sib-metadata.xml and
sibws-metadata.xml should also be present in this directory.
If clearing your browser's history files does not work, try reinstalling
the Administration Console application if you are running Version 5.0 or
5.1 (this is not possible in 6.0). To do so, see the following technote on
how to reinstall the Administration Console: Reinstalling
the adminconsole or filetransfer application
If that fails as well, open a Problem Management Record (PMR) with IBM
Support.
