MAINFRAME COMPUTING - 2021/2
Module code: COM3015
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
many large enterprises where security, reliability, availability, manageability, scalability and predictability are key concerns. 80% of the world's corporate data resides or originates on IBM mainframes. IBM mainframes (“System z”) are used by 95% of US Fortune 500 companies, 71% of global Fortune 500 companies, all of the top 25 worldwide banks, 23 of the top 25 US retailers and 9 out of 10 of the world's largest insurance companies. The mainframe operating system z/OS supports large-scale databases through DB2, IBM's flagship mainframe database software, and IBM's mainframe transaction serving software CICS handles more than 30 billion transactions per day.
The IBM Mainframe Computing module introduces students to mainframe concepts and “Large Systems Thinking” and provides the knowledge and skills necessary for using mainframes and preparing for a career in large systems computing. Experienced IBM IT professionals who are Subject Matter Experts (SMEs) in mainframe computing provide the module.
Software and hardware technologies that will be covered include System z and zEnterprise, z/Architecture, Parallel Sysplex, TSO/E, ISPF, datasets, DFSMS, ISPF, JES2, JCL, SDSF, DB2, CICS, CMS and REXX. Further topics that may be covered include RACF, SMP/E, PIPELINES, MQ and WAS.
Mainframe Computing in general provides for an interesting background to, and contrast with, Cloud Computing, and in relation to Business Systems and Distributed Computing more generally

Prerequisites / Co-requisites
Familiarity with operating systems and machine architectures would be helpful
Indicative content includes:
1. Fundamental concepts of the System z mainframe including its real-world usage, hardware and architecture.
2. Fundamentals of z/OS®, the IBM “flagship” mainframe operating system, covering hardware, virtual storage, workload management and interactive usage.
3. Mainframe workloads and the major middleware applications in use on mainframes today, including batch, enterprise database management and transaction serving.
4. Virtualisation of enterprise Linux workloads using the mainframe's hardware and microcode virtualisation support, along with IBM's hypervisor operating system z/VM which can host and manage thousands of separate Linux virtual servers securely and reliably on a single mainframe.
5. Data sets (DFSMS, allocation, VSAM, catalogs)
6. Batch processing: JES, JCL, SDSF, utilities
7. Systems programming: customizing the system, change control, system initialization
8. Advanced, specialised areas of mainframes such as z/OS systems programming, enterprise security or enterprise application programming.
9. Mainframe software, technologies and business considerations including, but not limited to: System z10; z/Architecture; Security overview (RACF, integrity); Parallel Sysplex and continuous availability; ISPF; DB2; CICS, MQ and REXX. Additional topics may include: Networking (TCP/IP, SNA, VTAM), WebSphere MQ, WebSphere Application Server (WAS).
|Assessment type||Unit of assessment||Weighting|
The assessment strategy is designed to provide students with the opportunity to demonstrate :
- Analysis and critical evaluation of the basic concepts of the System z architecture.
- Both theoretical and practical knowledge of the System Z Operating System
- A professional understanding of mainframe computing and business critical systems
Thus, the summative assessment for this module consists of:
- The individual project, which involves use of the Zeus mainframe and is assessed through written deliverables and development and configuration within the Zeus environment. (week 10). This addresses LO2
- A 2 hour unseen, closed book, written examination. This addresses all LOs.
Formative assessment and feedback
Students will be able to seek formative feedback in the lab sessions, and in relation to preparatory work for assessment, with the SMEs and use these opportunities to gauge their progress.
- provide students with a professional and practical understanding of the leading industry standard for mainframe design, the IBM Mainframe
- Expose the fundamental concepts of the System z mainframe including its usage, hardware and architecture
- Offer understanding of mainframe workloads and major middleware applications, virtualisation of enterprise Linux workloads, Introduce advanced mainframe topics such as z/OS systems programming, enterprise security or enterprise application programming.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
introduce students to mainframe concepts and “Large Systems Thinking” and provide the knowledge and skills necessary for using mainframes and preparing for a career in large systems computing.
The learning and teaching methods include:
- SMEs running weekly 4 hour “workshop” sessions face-to-face at the University. These typically involve 3 hours of presentations and an hour of practical investigation with a “live” mainframe system, IBM's European University hub mainframe “Zeus”.
- 24/7 access to Zeus from any internet-connected system to enable further investigation, and teavching materials via IBM’s Moodle-based materials.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
