In the previous article, “ISPF Power Tools: Working With the Data Set List Line Commands”, we examined many of the options available on data set lists by using line commands, which are typed to the left of an individual line on the display screen.

These new requirements drive the need for underlying tools that dynamically manage these workloads. Clearly, these tools must embrace what already works today—while accommodating what’s needed tomorrow—without disrupting operations…

For many organizations, the question of how to handle Big Data has become much more urgent over the last year. Big Data is of unprecedented size, is typically more unstructured, and is more likely to reside initially on public cloud server farms. It isn’t just a “hot topic”; it’s integral to the effective use of new analytics capabilities that are a high corporate priority…
