IBM WAS Admin

1. Installation and Configuration: Installing and configuring WebSphere Application Server instances on servers according to the organization's requirements. This involves setting up server profiles, configuring network settings, and tuning server parameters.

2. Application Deployment: Deploying Java EE applications to WebSphere Application Server environments. This includes configuring application resources, managing application deployment descriptors, and ensuring smooth application deployment processes.

3. Performance Tuning and Optimization: Monitoring and optimizing the performance of WebSphere Application Server instances to ensure optimal resource utilization and application responsiveness. This may involve tuning JVM settings, adjusting connection pool configurations, and optimizing database access.

Before diving into learning IBM WebSphere Application Server (WAS) administration, it's beneficial to have a strong foundation in several key areas of IT and software development. Here are some skills that can help you excel as an IBM WAS administrator:

1. Operating Systems: Understanding of operating systems, particularly Linux and Windows, is essential as WebSphere Application Server can be deployed on various operating system environments. Knowledge of basic system administration tasks such as file management, user management, and permissions is important.

2. Networking: Familiarity with networking concepts including TCP/IP, DNS, HTTP, and SSL/TLS is crucial for configuring network settings and ensuring connectivity between WebSphere Application Server instances and client systems.

3. Java EE: Proficiency in Java Enterprise Edition (Java EE) is necessary as WebSphere Application Server hosts Java-based web applications. Understanding Java EE concepts such as servlets, JSP (JavaServer Pages), EJB (Enterprise JavaBeans), and JMS (Java Message Service) is beneficial for application deployment and troubleshooting.
