The WebSphere Plugin comes with a plugin-key.kdb file upon installation The password of WebAS is set to expire by April 26, 2012 US EDT. If you have not generated a key file for the WebSphere plug-in you will run into this expiration. Web traffic via the web server and plugin will no longer function. Most customers don't use this keyfile, rather after configuring the plugin to a web server, they will generate a new keyfile and have it propagate to the web server location.
Important Notes
- This applies to IBM http server Plugin and when you use the default plugin kdb file which came while installing websphere.
- Checking the expiry through GUI is time taking and needs access to iKeyman utility. So, i am writing procedure to verify from commandline.
- No restart is required for this task
- The KDB file or Plugin configuration will be reloaded when web server restarts or a new plugin configuration is propagated from application server.
- If the password is not change before 26th April 2012, then plugin initialization will fail when you restart web server. And also you will not be able to propagate new plugin configuration from websphere application server.
1) First determine the location of your plugin installation [Default : IHS_installation/Plugins]
2) Next find out the location of the web server definition [default : IHS_installation/Plugins/config/webserver_definition]
3) Now make sure that you have GSKit installed on that machine [ls -l /bin/gsk7capicmd]
4) Find out the Plugin KDB file passowrd expiry using the below command : /bin/gsk7capicmd -keydb -expiry -db "IHS_installation/Plugins/config/webserver_definition/plugin-key.kdb" -pw *****
- If it returns Validity '0' ... means the password doesn't expire. You can stop here.
- If it returns the date like "26 April 2012", then you need to change the password.
5) If the password is expiring... use the following command to reset the passowrd validity
- backup the existing stath file [plugin-key.sth]
- Change password : /bin/gsk7capicmd -keydb -changepw -pw old_pass -new_pw new_pass -stash -db IHS_installation/Plugins/config/webserver_definition/plugin-key.kdb
- change the password back to the original passowrd. [not necessary but good to change to it back]
- verify the expiry date now : /bin/gsk7capicmd -keydb -expiry -db "IHS_installation/Plugins/config/webserver_definition/plugin-key.kdb" -pw *****
6) Please note that, it is a good practise to change the passowrd for the template KDB file as well. This can be found under IHS_installation/Plugins/etc directory. The default password is "WebAS" for this file.
- Check the expiry [/bin/gsk7capicmd -keydb -expiry -db "IHS_installation/Plugins/etc/plugin-key.kdb" -pw *****]
- Change password, if required [/bin/gsk7capicmd -keydb -changepw -pw old_pass -new_pw new_pass -stash -db IHS_installation/Plugins/etc/plugin-key.kdb ]
- Change the password back to default password [/bin/gsk7capicmd -keydb -changepw -pw old_pass -new_pw new_pass -stash -db IHS_installation/Plugins/etc/plugin-key.kdb ]
- Verify validity again [/bin/gsk7capicmd -keydb -expiry -db "IHS_installation/Plugins/etc/plugin-key.kdb" -pw *****]

Hello All We are compiling all my old blog posts and articles about the new WebSphere Application Server into one big document. Since it covers all the new features of WAS v8, i named it as WebSphere Application Server v8 Primer. We hope this series of articles/documents will give you a smooth transition to WAS v8 from the previous versions. We are planning to publish the series on " websphereapplicationservernotes.wordpress.com" . So we will not be duplicating the same content here on GWC. Sorry for that but you can import all the documents using google docs. we will post list of topics under this series and update the google docs links when they are published. Note: We are not promoting our blog and we are just trying to avoid duplication of the content and the project is more of consolidation of work done by Joseph Amrith Raj.

Link to part-5 of this troubleshooting series.
Fifth part of this series [do you know who did it? Troubleshooting issues in websphere application server], we will be discussing issues with the class loading. The below document explains the class loader, how it works, how websphere implements class loader, available class loader policies and combinations etc… then, finally we use the toll ‘class loader viewer’ to check the loaded classes at what level they are available.
