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 2 Enterprise Edition Specification
V1.3.
- The programming models and specifications for application components
(Enterprise beans, Web applications, and client programs) supported in the
J2EE 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.
