TCP/IP troubleshooting on z/OS (NW79G)

• Support teams handed mainframe network incidents with no idea where to start.
• Administrators whom IBM always asks for more data than they collected.
• Anyone with a network performance problem nobody manages to reproduce.

• The TCP/IP commands and utilities used when diagnosing
• How traces are activated and read
• Following a connectivity problem step by step
• Diagnosing the services: FTP, Telnet and name resolution
• Network performance problems
• What data to collect before raising a case with IBM

• Labs on a running z/OS TCP/IP stack, with traces and diagnosis on real cases.
• Taught directly by IBM Champion instructors from the SIXE team.
• Credly badges available: credly.com/organizations/sixe/badges
• Flexible format — online, classroom or onsite — in closed groups, priced per attendee, in the language of your choice (ES / EN / FR).

Do we read real traces?
Yes, and it is the bulk of the course: turning them on, formatting them and getting the answer out of them, which is not the same as looking at them.

Does it cover what IBM asks for in a case?
The last block is exactly that: what to collect and when, so you do not have to reproduce the problem a second time.

How is it organised and what does it cost?
It runs as a closed group, priced per attendee. Tell us how many you are and which dates suit you, and we will send a proposal.
