Example: “I am familiar with a variety of platforms, including Windows, Linux, and AIX. I am also familiar with a variety of web servers, including Apache, IIS, and Websphere.”

What do you think are the most important skills for a WebSphere Administrator?

The interviewer is trying to gauge the candidate's understanding of the skills necessary to perform the duties of a WebSphere administrator. It is important to ensure that the candidate has the necessary skills to perform the job because a WebSphere administrator is responsible for managing and configuring WebSphere application servers.

Example: “There are many important skills for a WebSphere Administrator, but some of the most important include:

1. Understanding of WebSphere architecture and components - It is important for a WebSphere Administrator to have a good understanding of the different components that make up WebSphere, as well as how they interact with each other. This knowledge is necessary in order to be able to effectively configure and manage a WebSphere environment.

2. Experience with configuring and managing WebSphere environments - A WebSphere Administrator should have experience configuring and managing WebSphere environments. This experience will allow them to effectively troubleshoot problems that may arise, and will also help them to better understand the capabilities and limitations of WebSphere.

3. Good communication skills - A WebSphere Administrator must be able to effectively communicate with other members of the team, as well as with customers or clients. This communication is necessary in order to coordinate activities, exchange information, and resolve issues.

4. Good problem-solving skills - A WebSphere Administrator must be able to identify problems and then find solutions for them. This skill is necessary in order to keep the environment running smoothly and to avoid or resolve any potential issues that could arise.”

How would you go about troubleshooting a WebSphere issue?

An interviewer would ask "How would you go about troubleshooting a WebSphere issue?" to a Websphere Administrator in order to gauge the Administrator's problem-solving skills. It is important to be able to troubleshoot WebSphere issues because administrators are responsible for ensuring that the WebSphere application server is running smoothly and efficiently.

Example: “There are a few steps that can be taken when troubleshooting a WebSphere issue. First, check the SystemOut.log and SystemErr.log files for any errors that may have been logged. Next, check the WebSphere Application Server log files for any errors. Finally, check the Web server log files for any errors. If all of these logs are clear, then the issue may be with the application itself.”

What do you think are the most common problems with WebSphere?

The interviewer is trying to gauge the candidate's understanding of Websphere and its potential problems. It is important for the interviewer to understand how the candidate would identify and solve problems with Websphere.

Example: “There are a number of common problems that can occur when using WebSphere. Some of the most common problems include:

-Memory leaks. Memory leaks can occur when applications fail to release memory properly. This can lead to OutOfMemoryErrors and other stability issues.

-Classloader leaks. Classloader leaks can occur when applications fail to release classloaders properly. This can lead to OutOfMemoryErrors and other stability issues.

-JVM crashes. JVM crashes can occur for a variety of reasons, including memory leaks, configuration issues, and hardware problems.”

What do you think are the most common mistakes made when configuring WebSphere?

There are a few potential reasons why an interviewer might ask this question:

1) To gauge the candidate's technical knowledge - A good answer to this question would demonstrate that the candidate is familiar with the most common mistakes made when configuring WebSphere, and how to avoid them.

2) To assess the candidate's problem-solving skills - The interviewer wants to see if the candidate is able to identify potential problems and come up with solutions to fix them.

3) To evaluate the candidate's ability to communicate effectively - This question allows the interviewer to see how well the candidate can explain their thoughts and ideas in a clear and concise manner.

Example: “The most common mistake made when configuring WebSphere is forgetting to set the JVM Heap Size. The JVM Heap Size needs to be large enough to accommodate your application, otherwise your application will not perform as expected. Another common mistake is forgetting to configure the Web Container thread pool size. The Web Container thread pool size needs to be large enough to handle the number of concurrent requests your application will receive.”

What performance tuning techniques are you familiar with?

An interviewer would ask this question to a Websphere Administrator to gain insights into the Administrator's understanding of how to improve the performance of a Websphere system. This is important because Websphere systems can be complex, and performance tuning is essential to keeping them running smoothly. By understanding the techniques that are available, the Administrator can make informed decisions about how to best optimize the system.

Example: “There are a number of performance tuning techniques that can be used to improve the performance of WebSphere applications. Some of the most common techniques include:

1. Optimizing the application code - This involves making sure that the application code is as efficient as possible. This can be done by using caching, optimizing SQL queries, and using efficient algorithms.

2. Configuring the WebSphere environment - This includes setting the appropriate values for various WebSphere parameters such as connection pool sizes, thread pool sizes, and JVM settings.

3. Monitoring the WebSphere environment - This helps to identify bottlenecks in the system so that they can be addressed. Monitoring tools such as Tivoli Performance Viewer and IBM Support Assistant can be used for this purpose.

4. Tuning the operating system - This involves making sure that the operating system is configured properly to support WebSphere applications. This can include setting appropriate values for kernel parameters, network parameters, and file system parameters.”

What do you think is the best way to monitor WebSphere?

The interviewer is asking this question to gauge the candidate's understanding of how to properly administer a WebSphere server. It is important to monitor WebSphere so that any potential issues can be quickly identified and addressed. By knowing how to properly monitor WebSphere, an administrator can prevent problems before they occur, or at least identify and resolve them quickly when they do occur.

Example: “There are a few different ways to monitor WebSphere. The best way depends on what you want to monitor and how much detail you need.

The WebSphere Application Server Performance Monitoring Infrastructure (WPMI) is the recommended way to monitor WebSphere. WPMI uses operating system and JVM performance monitors to collect data about WebSphere performance. This data can be used to identify performance bottlenecks and tune the system accordingly.

The WebSphere MBean Server is another way to monitor WebSphere. MBeans are Java objects that expose information and statistics about the running system. WebSphere provides a set of predefined MBeans that can be used to monitor various aspects of the system, such as JVM performance, application deployment, and datasource usage.

The WebSphere administration console also provides some basic monitoring information, such as JVM statistics, application deployment information, and datasource usage.”

What tools do you use to manage WebSphere?
