Mainframes are computers, which particularly qualify for efficient and reliable data processing. They are deployed especially in financial institutes, insurance companies and enterprises, in which a lot of transactions are handled. Mainframes excel in their high data throughput and their reliability, which is achieved among others by redundant hardware. At the moment there is a shortage of professionals, which can administrate and program mainframes, since research and teaching in the area of mainframes decreased in the last decades. One of the reasons for this is the fact that universities often don’t have the means to operate a mainframe. With the System z Development and Test Environment (zD&T) IBM develops an application, which emulates the IBM’s Mainframe architecture on a x86-computer. With this one can run IBM’s mainframe operating system z/OS on a x86-computer. Thus zD&T represents an alternative to a physical mainframe to do research and teaching in the environment of mainframes. As part of this thesis zD&T is installed on the chair’s servers and the process of the installation is documented. Subsequently a course is designed, in which initially the installation and configuration of zD&T and z/OS is shown, and afterwards different basic software components of mainframe programming are introduced.
