Understanding WebSphere in Linux, UNIX & Windows environments
This two-stage course introduces the world of WebSphere. In the first part, the Enterprise Java (J2EE) platform (the basis for the WebSphere architecture) is explained. The integration of Java with existing (enterprise) systems is also covered.
The second part of the course is designed for Linux, UNIX and Windows environments users who, if they have not already encountered a WebSphere Application Server (WAS) in their organisation, are likely to in the near future. This section of the course explains the WebSphere Application Server at a conceptual level, and introduces WAS administration and security, as well as covering scalability, availability and failover issues.
On successful completion of this course, attendees will be able to:
- discuss the architecture and possibilities of Enterprise Java (J2EE)
- describe the pros/cons of different solutions for typical business problems
- list the most recent J2EE APIs
- understand the integration of Java with existing enterprise systems
- list the products and tools in the J2EE domain
- describe the set-up of this environment: web, web applications, web servers , etc.
- explain the role of Java and the importance of an architecture combined with application components
- describe the role of WebSphere Application Server
- discuss the relationship of WAS to its operating environment
- understand WAS administration features
- appreciate WAS security issues.
No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.
Application programmers and administrators who are going to use web applications in an enterprise environment, based on a WebSphere platform.
Some familiarity with Internet concepts and Java would be an advantage, but is not mandatory. For day two, an understanding of your own Linux, UNIX or Windows environment is required.
