As a WebSphere administrator, you should be aware of taking thread dumps and tools to analyze them.

Application troubleshooting is always exciting and challenging. However, if you were not equipped with required tools, then it would be frustrating.

Putting your WebSphere behind Web Server is essential for various reasons including performance, security, and scalability. If you are working as a WebSphere administrator or just started then one of the tasks you will be involved in is to connect IHS with WAS.

IBM released WebSphere Application Server (WAS) 8.5.5 in 2013 and since then market share is growing but slowly. It’s surprising to see version 6 is still used by 50% where version 8 is just 9.6%.

One of the WebSphere Administrator tasks is to keep the environment up-to-date and you should be familiar with the process. This assumes you already have WebSphere 7 installed and running on Linux environment.
