z/OS Communications Server Part1– SNA & VTAM [VTAN]

 This updated, four-day course is the second part of the definitive z/OS Communications Server training programming. This course explains in detail how TCP/IP works in a z/OS environment. Installation, profile definition and implementation are all taught in depth. All versions of TCP/IP for z/OS are covered, along with all the servers. Additionally, all the essential and important configuration options are explained and examples are provided.
