Bridging the z/OS Mainframe Performance & Capacity Skills Gap

B._Phillips-web0By Brent Phillips

Many, if not most organizations that depend on mainframes are experiencing the effects of the mainframe skills gap, or shortage. This gap is a result of the largely baby-boomer workforce that is now retiring without a new generation of experts in place who have the same capabilities. At the same time, the scale, complexity, and change in the mainframe environment continues to accelerate. Performance and capacity teams are a mission-critical function, and this performance skills gap represents a great risk to ongoing operations. It demands both immediate attention and a new, more effective approach to bridging the gap.

Is Your Car or Mainframe Better at Warning You?

Imagine driving your car when, without warning, all of the dashboard lights came on at the same time. Yellow lights, red lights. Some blinking, while others even have audible alarms. You would be unable to identify the problem because you’d have too many warnings, too much input, too much display. You’d probably panic!

That’s not likely, but if your car’s warning systems did operate that way, would it make any sense to you? Conversely, if your car didn’t have any dashboard at all, how would you determine if your car was about to have a serious problem like very low oil pressure or antifreeze/coolant? Could you even operate it safely without an effective dashboard? Even the least expensive cars include sophisticated monitoring and easy interpretation of metrics into good and bad indicators on the dashboard.

You have a need for a similar dashboard of your z/OS mainframe to alarm you. When any part of the infrastructure starts to be at risk of not performing well, you need to know it, and sooner is better. By being warned of a risk in an infrastructure component’s ability to handle your peak workload, you can avoid the problem before it impacts production users or fix what is minor before the impact becomes major. The only problem is that the dashboards and reporting you’re using today for your z/OS infrastructure, and most monitoring tools, do not provide this type of early warning.
