Introducing domain 'MVS - z/OS'

Definition

MVS - z/OS

MVS (Multiple Virtual Storage) was the most commonly used operating system on IBM mainframe computers. First released in 1974, MVS was renamed by IBM to MVS/XA (eXtended Architecture), to MVS/ESA (Enterprise Systems Architecture), then to OS/390 when UNIX services were added, and finally to z/OS when 64-bit support was added on the zSeries models; but it remains fundamentally the same operating system.

Importance

Mainframes outdated? No-way! A major part of existing corporate data and applications still runs smoothly on a trusted, good old mainframe!

Once indeed, they were considered obsolete. They were to be replaced by cheaper, simpler, more flexible 'distributed' alternatives. For some applications, these distributed alternatives are to be considered a valid option. And granted - the term 'mainframe' does sound old fashioned. Today, the term 'Enterprise Server' has a much nicer ring to it! This new term stresses to importance of this 'old' platform as a consolidator for an important set of distinct individual servers - database servers, mail servers, security servers, web servers. All services available from this one single 'Enterprise Server'.

ABIS still believes in the importance of the mainframe; even after 20 years, it still remains the focus of much of our attention. We are still convinced of the importance of application development and systems management on the z/OS platform. And although clearly changes can be observed with respect to the way in which the platform is used and managed, ABIS is ready to give it all the attention this platform deserves. This fact, combined with our knowledge of related subsystems (CICS, DB2, IMS), and our expertise with respect to new application development paradigms, is our added value!

Core competencies

Based on the dominant role played by the z/OS platform, ABIS has identified the following core points of interest.

Given the importance of the z/OS platform, ABIS provides all required expertise for an efficient handling of the platform. Developer, architect, systems manager, administrator - you will find all required - even conceptual - knowledge you desire and need.

Starting as an application developer on z/OS requires very specific z/OS knowledge - practical experience with z/OS system specifics (ISPF, JCL, ...). Furthermore, additional knowledge with respect to the different subsystems to be used in day-to-day activities is required: DB2, IMS, CICS. We focus on technical aspects as well as on different ways to effectively deal with the most commonly occurring challenges. Performance and management effectively are considered as well.

z/OS and related subsystems have to be configured and managed - a specific domain treated in detail together with our partners. No an easy task - given the amount of new functionality for which these subsystems are used. We focus for example on parallel sysplex, z/OS Unix System Services, RACF (Security Server).

Our offering ...

On the next set of pages, our z/OS course offering - including course description - is discussed in detail. Courses can be followed stand alone as well as part of a coordinated course track. Obviously, tracks can be designed based upon your proper requirements.
