5 Reasons IBM z/OS Infrastructure Performance & Capacity Problems are Hard to Predict and Prevent

B._Phillips-web0By Brent Phillips

Solving z/OS infrastructure performance and capacity problems is difficult. Getting ahead of performance and capacity problems before they occur and preventing them is more difficult still. This is why it takes years, and decades even, for performance analysts and capacity planners to become experts.

And together, with the rapid retiring of the current experts, the difficulty in becoming an expert is why the performance and capacity discipline for the mainframe is experiencing a significant skills gap. It is simply too difficult and time consuming to understand what the data means for availability, let alone derive predictive intelligence about upcoming production problems within the complex IBM z Systems infrastructure.

The primary root causes of this performance and capacity management problem are:
