IBM Course Code: NW791
This course is designed to give you the skill required to diagnose and debug TCP/IP problems when operating on z/OS. This skill consists in developing knowledge of commands and tools together with a methodology in tackling TCP/IP problems.
The lab activity and paper projects provide an opportunity to debug real problems.
What You'll Learn
- Learn what commands are useful in a z/OS environment to control TCP/IP resources, the TELNET application, and debug TCP/IP simple network problems
- Learn which trace types (packet, TELNET, FTP, and so forth) are available in a z/OS environment and know:
- What kind of information can be found in a trace
- When to activate a trace
- How to activate a trace
- How to interpret a trace (for the packet trace there is a dedicated topic)
- Use the proper diagnostic technique to approach TCP/IP problems
- Describe the Syslog function in the UNIX environment and know how to configure the /etc/syslog.conf file
- Understand how to handle and modify the translate tables used by many TCP/IP applications that connect to remote systems which use ASCII character coding
- Activate and interpret several trace types, and debug some real problems which involve the use of various application protocols.
Who Needs to Attend
This intermediate course is for anyone who works on TCP/IP networks and provides support in the resolution of communication problems on z/OS.
You should complete:
- TCP/IP for z/OS Implementation Workshop (CB695)
You should have knowledge of z/OS.
