In a large-scale enterprise system such as the WebSphere® Application
Server for z/OS® environment,
diagnosis might require a variety of skills to progress from a symptom to
fixing the underlying cause of that symptom.
Because WebSphere Application
Server for z/OS exploits
many of the qualities and services that are unique to the z/OS operating
system, diagnosing system-related problems might require skills in the following
areas:
- Parallel sysplex
- TCP/IP
- Security Server (RACF®) or the equivalent
- Database systems such as DB2 Universal Database for z/OS
- UNIX® Systems
Services
You can find information for many of these topics in the publications
available through the z/OS library
Web site.
Similarly, diagnosing application-related problems might require a variety
of skills because of the variety of application components that WebSphere Application
Server for z/OS supports.
Programmers who diagnose application problems in the WebSphere Application Server for z/OS environment
need some familiarity with the following:
- The roles defined in the Sun Microsystems Java Platform, Enterprise Edition (Java EE)
Specification V1.3.
- The programming models and specifications for application components
(Enterprise beans, Web applications, and client programs) supported in the Java EE
1.3 environment.
- The process of assembling, deploying, installing, and running server
applications and clients in the WebSphere Application Server for z/OS environment.
- Various tools such as the WebSphere Application Server for z/OS error
log, and the job logs for programs running on z/OS.
