Technical Skills & Experience

• 6. Can you explain the basic architecture of Weblogic servers?
  Answer: Weblogic servers follow a distributed architecture, with a central Administration Server managing a domain and one or more Managed Servers running applications. The Administration Server stores and maintains configuration information, while the Managed Servers run the applications and communicate with the Admin Server.
• 7. How do you configure a Weblogic server?
  Answer: To configure a Weblogic server, you need to create a domain, which is a logical grouping of Weblogic servers. You can then configure various components, such as clusters, machines, and applications, within the domain. You can use the Weblogic console or scripts to configure these components.
• 8. In your experience, how do you troubleshoot common performance issues in Weblogic servers?
  Answer: Performance issues in Weblogic servers can be caused by various factors, such as high load, memory leaks, or incorrect configurations. To troubleshoot, I start by analyzing server logs and monitoring tools to identify the root cause of the issue. I then make necessary adjustments to server configurations, such as increasing heap size or tuning thread pools, to resolve the issue.
• 9. How do you deploy an application on a Weblogic server?
  Answer: To deploy an application on a Weblogic server, you can use the Weblogic console or scripts to package and deploy the application file (WAR, JAR, or EAR) on the server. You can also use the Deployment Manager to deploy the application to multiple servers simultaneously.
• 10. How do you secure a Weblogic server?
  Answer: Security in Weblogic servers can be achieved through various means, such as setting up SSL encryption, configuring user authentication, and setting up firewalls. In addition, you can use Security Realms and Role Mapping to control access to server resources based on user roles.

Behavioral Questions

• 11. Tell me about a time when you faced a challenging issue while configuring a Weblogic server. How did you handle it?
  Answer: In my previous job, I had to configure a Weblogic server for a complex application with multiple components and dependencies.

Situational Questions

• 16. If you encountered a critical issue in a production Weblogic server, what would be your approach to resolving it?
  Answer: My first step would be to analyze the server logs and get an understanding of the issue. I would then try to isolate the issue and make any necessary configuration changes to resolve it. If the issue persists, I would escalate it to my team members and follow the established protocols for handling critical issues in production.
• 17. How would you handle a situation where a developer reports that their application is not performing well on a Weblogic server?
  Answer: I would start by analyzing the server logs and performance metrics to identify the root cause of the issue. I would also gather information from the developer, such as the application code and any recent changes. Based on my analysis, I would make the necessary optimizations and work with the developer to resolve the issue.
