Master Z

So you are now working on the mainframe platform. You wanted to keep up with the latest and greatest or you just wanted to get to know a topic or feature associated with the mainframe. Either you just started your job in a mainframe shop or you are an experienced mainframer wanting to know some specific information on the mainframe. Where do you start? Where do you go to look?

In this article, I suggest some helpful ways to get you started. If you haven’t already seen my earlier article about the latest trend in Z, the mobile Apps, then I highly recommend you read that article first (hint: some apps I suggested in that post will be of great use here for you to get started on topics!).

This information isn’t particularly aimed at someone wanting to get started with mainframe technology. Although some of the approaches mentioned below may be relevant to you as well, there are other better venues for you to get started on the mainframe. I will make a separate detailed post for you, I promise! Here we go with the list (in no particular order):

1. Z Favorites

3. IBM Redbooks

IBM Redbooks core content typically provides positioning and value guidance, installation and implementation experiences, typical solution scenarios, and step-by-step “how-to” guidelines. It sometimes reflects working experiences about a specific topic and often includes sample code and other support materials.

By the way, while researching for this article, I got curious on the name “redbooks” – why red books? Why not blue or white or green book? A quick search on Wikipedia gave me the following on the history:

It happened that in the Center storeroom was a pallet of red oak tag that had been previously ordered to be made into various posters to hang around the center. Without much thought, this heavier red paper was stapled on as a protective cover to the document, printed with the WTSC logo (a series of circles representing the world that one of the SE’s had sketched out) and the first of the IBM Redbooks was born.

4. zNextGen community

zNextGen is a user-driven community of over 1,000-members, representing 24-countries for new and emerging Z System professionals that has the resources to help expedite your professional development and skills-sharpening.

Pro tip #1: Subscribe to the digital copies of these cost-free magazines and tech journals.

8. Mainframe annual surveys

Every year, several surveys are conducted across the mainframe community. These surveys are conducted among various mainframe users. The results of these surveys offer insights about the general trends of the mainframe technology. There is one from BMC, one from Syncsort and one from Arcati. If you are a strategist then you need to keep an eye on these surveys. The surveys reveal key trends that shape the future of the technology. For example, surveys may disclose, key challenges the industry is facing, the top priorities going forward, growth trends, mainframe modernization and changing workforce etc.

Pro tip #1: Search Google for “Annual Mainframe Survey” and subscribe or register to download the digital copies of these surveys.

Pro tip #2: Even if you are not a strategist, but a mainframe professional/user, it is good idea to be aware of where the industry is heading. With several myths floating about mainframe computing (such as outdated, dead, irrelevant etc.), it is difficult get an unbiased view of the industry. The annual surveys offer just that – an actual mainframe user driven surveys results.

There you go! If you are a system programmer, or an application programmer, or in sales, or an architect or a strategist, or a mainframe user, listed above are some of the best ways you can keep on top of Z!

My approach: When I am planning to attend either SHARE or CMG conferences, I look for the sessions, labs or workshops that I am interested in at that time. If conferences are not imminent then I usually search for handouts from earlier conference proceedings on the topic either from SHARE or CMG conferences or zNextGen virtual meetups. That gives me a quick start on the topics I need. These SHARE, CMG, zNextGen, IDUG conference presentations stems from experts on the subject, and they do good job explaining concepts. I then go and search on zFavorites for IBM Redbooks or other manuals to get in depth concepts of topics.

In addition, keeping up with what’s going around the industry, I follow various mainframe centric conferences, read magazines and annual surveys, and check Z Favorites. That should give me a solid understanding of the trends in the technology I admire!

Now, It’s quiz time.
