z/OS Networking

This course examines network theory and architectures (TCP/IP and SNA/APPN), the business problems to be solved and actual implementations, as well as security, administration, and operations. A PC with Windows is required to complete assignments where you learn and investigate general computer networking, and 2 hands-on labs where you will work on your own virtual z/OS system: examining, modifying, and repairing its network. The labs and lectures are an introduction to the tasks of a z Systems network administrator and will enable you to discuss data center issues with network managers as an informed and active participant.
