Audience
This course is for the Information Systems communications professional who is planning to install TCP/IP for z/OS and for TCP/IP users who are interested in installing and customizing IBM's TCP/IP product in interoperability environments and main applications.
Prerequisites
- You should understand basic concepts and architecture of TCP/IP and the TCP/IP protocols.
- You should be familiar with z/OS systems and networking operations, and be familiar with z/OS UNIX Services configuration and usage.
- You should also have a basic knowledge of data communications.
Duration
5 days. Hands on.
Course Objectives
This course is intended to replace and enhance the content provided by the old IBM “CB69G - TCPIP implementation” course which was withdrawn by IBM.
CB69G enabled students to configure and understand a Z/OS Comms Server TCPIP stack, but despite students needing to have a good understanding of VTAM and configure it, the course paid only basic lip service to any references to VTAM.
Whilst most students will have a basic understanding of TCPIP; VTAM/SNA/APPN will be alien to them, but is required knowledge to build, customise and support TCPIP on Z/OS.
This course intends to give the students an understanding of VTAM and the ability to customise it, so as to build, sustain and support a TCPIP stack on Z/OS. The student will therefore build, customise and start a TCPIP stack from scratch, adding VTAM definitions and activating them as required for the extensive hands on course labs.
Thus, the course relies heavily on practical sessions, with students creating their own Comm server TCPIP stack and connecting it to an instructor system, using both TCPIP & VTAM/SNA/EE links.
