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.
Familiarity with the z/OS environment and the ability to use TSO/ISPF.
This course introduces the issues, problems, and solutions to the challenges in integrating SNA and TCP/IP networks. Emphasis is placed on open standard solutions (via RFCs,) although some innovative vendor-specific solutions are also included. All variations of SNA are covered, including subarea SNA and APPN (including APPN/HPR). This course is primarily concerned with identifying the areas of difficulty and suggesting standard solutions to overcome these, the aim is to provide attendees with the background information necessary to make sensible choices for their own networks.
Existing knowledge of either (or both) SNA and TCP/IP are highly desirable, although a review of the operation of these networks is provided
This is the essential course for anyone who needs a solid understanding of TCP/IP networks. The course describes and explains the concepts & features of TCP/IP, providing a complete introduction to the TCP/IP protocols, services & applications. Assuming no existing TCP/IP knowledge, it covers all aspects of TCP/IP, the Internet and Intranets, including security issues. Common user and system applications are explained (including FTP, Telnet, WWW, DNS, NFS, and SNMP), in addition to a detailed examination of the major protocols, message formats and addressing methods
An understanding of networking principles and terminology is required
This course explains how to set up security for the z/OS networking environment. With the advent of TCP/IP and the Internet, network security requirements have become more stringent and complex. The Communications Server, along with other elements in z/OS including RACF, provides IP security functions. These protect data privacy and integrity, z/OS, and system resources from unauthorized access
A sound knowledge of TCP/IP concepts and protocols. This can be gained by attending the course TCP/IP Fundamentals [CTCP] or TCP/IP in a z/OS environment. This can be gained by attending TCP/IP for z/OS – Implementation [CTMZ] A good knowledge of UNIX System Services is also needed, which can be gained by attending the course Using RACF under UNIX System Services [RAUS].
