Health Check for Your z/OS Systems Should Include Coupling Facility Activity

 

As another New Year begins, most of us are open to some new practices that improve life both at home and at work. Probably the most common challenge we face personally in the new year is our weight. I put on my share, and it’s never easy to get back on track! Reducing calories on the intake side is a good start, however, coupled with a regular regimen of exercise, diet has a multiplying effect. Suddenly, the effects of exercise go far beyond the goal that drove the change in activity, and it pervades other areas.

It’s no different in IT.

(Here’s a reference of the exercise multiplier and an example article showing the many other exercise benefits.)

Whether you have just completed your year-end budgets or not, it won’t be long before cost pressures, time pressures and all the other pressures of new projects squeeze many of us into ‘surviving the next day’ versus moving along a progressive path of improvement. I’ve been there.

Root Cause Analysis for z Systems Performance – Down the Rabbit Hole

By Morgan OatsDown the Rabbit Hole - Root Cause Analysis

Finding the root cause of z Systems performance issues may often feel like falling down a dark and endless rabbit hole. There are many paths you can take, each leading to further possibilities, but clear indicators as to where you should really be heading to resolve the problem are typically lacking. Performance experts tend to rely on experience to judge where the problem most likely is, but this may not always be adequate, and in the case of disruptions, time is money.

Performance experts with years of experience are more likely able to resolve problems faster than newer members of the performance team. But with the performance and capacity skills gap the industry is experiencing, an approach is needed that doesn’t require decades of experience.

Rather than aimlessly meandering through mountains of static reports, charts, and alerts that do more to overwhelm our senses than assist in root cause analysis, performance experts need a better approach. An approach that not only shines a light down the rabbit hole, but tells us which path will lead us to our destination. Fortunately, IntelliMagic Vision can be your guide.
