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

OVERVIEW

This new, 4-day course is the first part of the definitive z/OS Communications Server training programmer. It is an essential requirement for all personnel working in or with an SNA (APPN and SubArea) network. This in-depth course introduces and explains the concepts, terminology and configuration of SNA, VTAM and APPN. Emphasis is placed upon, but is not limited to, VTAM implementations of SNA in both an APPN and SubArea Network. Additionally, APPC is explained in detail. The course also teaches how to define the network in order to optimize response time and throughput, especially in a Parallel Sysplex.
 

Please note that this is a highly practical course where each student will have their own VTAM/APPN Network.
