BMC Mainframe: Mainframe Networks - an Introduction
The course is developed and delivered by © RSM Technology.
This two-day course introduces mainframe personnel to networks in a Z Systems environment. The course describes mainframe networks at a conceptual and terminological level, giving attendees a sufficient depth of detail to enable them to discuss issues relating to their organization’s networks with confidence and understanding.
The course introduces the important aspects of SNA, VTAM, APPN and TCP/IP, and explains their relationships. Attendees are also taught about the use of Console commands and how to use TSO commands to interrogate a TCP/IP network.
Several practical, hands-on exercises are included throughout the course.
