ISYS 4453/5453 –Introduction to Enterprise Servers Wednesday evenings– 5:30 to 8:20 PM Hunt 220
What is the first thing that comes to you mind for the word mainframe?
Common Challenges • System z is too expensive • System z is legacy, stabilized and new development should be on other platforms • Then, the z will eventually go away • I’m afraid if I use z I will have a “single point of failure” • The MF skills are all ready to retire—who will support “anything” MF going forward?
Questions • In what decade was the first MF? • What was its name? • Last year, the world produced more transistors than grains of rice? t/f • What MF name was used for the first follow on MF from above? • By 2010, there will be more than 30 billion RFID tabs in circulation. t/f • What version of MF would used in the 90’s? • What is the major database used on MFs? • There are more than 1 billion camera phones in use today? t/f • What has been the most prevalent programming language on the MF? • What are “modern” languages being used on the MF?

Why take this course? • Jobs • Know companies like Baldor, Data-Tronics, Dillards, JB Hunt, Walmart, etc. • http://mainframejobs.zjournal.com/a/jbb/find-jobs • Additional computing platform that many students do not have opportunity to learn • Broading skillsets as System z becomes more open and accessible • Fast growing server—appears to continue as a major computing platform • RAS—Reliability, Accessibility, Scalability • Did I say Jobs? Or did I say Jobs?
Platform choice – Fit for purpose, workload and situationMany factors influence a platform selection, making it difficult to present a simple selection matrix.
System z clouds achieve operational efficiencythrough economies of scale
A government organization consolidates applications and data to drive down costs of hardware, software and management by 70%!

Application Performance Characteristics – what fits on which platform? Workload performance varies by application and can be best served by different platforms or the right mix of multiple platforms.
Course Goals • Be able to express the benefits of a mainframe including • Z Series architectural concepts • Consolidation and TCO advantages of this environment • Major applications running on the mainframe as well as the type of applications for which it makes sense to put on a mainframe • The role of JCL for scheduling and batch processing • How z/VM exploits virtualization and allows Linux to be run as a virtual guest • Know the value of Linux on the mainframe
Course Goals (cont) • System z skills under zOS • Be able to navigate TSO/ISPF and RDz environments • Be able to create partitioned datasets; edit, upload, download files • Be able to used selected utilities including IDCAMS to create VSAM files • Be able to run simple programs that utilize files and JCL on the mainframe
Course Goals (cont) • Linux skills using the Integrated Facility for Linux. • Be able to effectively work in the Linux environment including RDz • Be able to do essential system tasks • Be able to work with files including creation, editing, coping, etc. • Be able to write basic Linux scripts • Be able to create Web sites using LAMP (Linux, Apache, mySQL, PHP)
