SUMMARY:   This practically focused class covering addresses the needs of network technicians responsible for the planning and implementation of modern SNA over IP techniques in the modern mainframe environment. This can involve migration from a SNA/VTAM Subarea network to a SNA/VTAM APPN network and lead to the implementation of Enterprise Extender. Enterprise Extender (EE) is a solution which consolidates both SNA and IP network traffic over a single networking protocol – typically IP. PREREQUISITES:   Some experience of working with VTAM/SNA and/or TCP/IP in the mainframe environment. DURATION:   3 days. OBJECTIVES:   Describe a traditional subarea SNA network Describe TCP/IP implantation on the mainframe Describe the SNA/APPN/HPR architecture Migrate from a VTAM/SNA subarea network to a mixed VTAM/SNA subarea and APPN network. Code the VTAM parameters required to migrate from a VTAM/SNA subarea network. Implement an Interchange Node, Migration Data Host, Network Node or End Node. Use VTAM commands to control an APPN network Take advantage of APPN's dynamic definition capabilities Describe the Enterprise Extender Implement the Enterprise Extender COURSE CONTENT:   Review of traditional VTAM/SNA Review of TCP/IP on the mainframe The Communications Server Component Introduction to APPN APPN connection management Topology Database and Exchange APPN directory services Session establishment Additional APPN functions and Considerations including DLUR/S APPN High Performance Routing (HPR) Exploiting SNA traffic over IP The Enterprise Extender (EE) Implementation of EE Extended Border Node using EE PCOM as DLUR node over EE EE Performance Various other EE options and exploitation HW/08
