Mainframe Modernization Overview


Duration: 1 day

Method: Instructor led, lecture only with live demos.

Price: $600.00

Course Code: MF7000


This course will be of interest to all mainframe personnel. It does include some technical details oriented to various technical personnel. However, it will also provide management with necessary information to show how the mainframe has been modified to fit into today’s complex infrastructure.


You may associate the IBM mainframe with legacy applications and think that it is old and stodgy. Think again! The past few generations of the hardware have been improved to favor implementation of today’s newer environments. This includes support for things like Perl, Python, Java, Docker, cloud processing, and Node.js. All of this plus more along with the heritage things like, CICS, MQ, Db2, and COBOL. First we will take a brief look at the last three generations of the hardware and their capabilities. Next we will have a look at the new features on z/OS like z/OS Connect, containers, WebSphere Application Server (more than a mainframe based web server), z/OSMF, Unicode System Services, and a few other modern development tools. We will then have a look at the updates to heritage software products like COBOL, CICS, Db2, MQ, and IBM Developer for Z in support of these new features. Last we will look into some other software like Rational Team Concert (RTC), zOpenDev, urban code, and new scripting tools used in DevOps processing. Please remember, that this is an “overview” so this class to help you understand some of the things you should consider on the modern mainframe. Hands-on courses for each major topic are currently being developed.


Upon successful completion of this course, the student will be able to:

  • Understand the components of a modern mainframe.
  • Determine which of the components discussed should be further investigated in their enterprise.
