Code Change and Resilience

A lot of our projects recently have been all about resilience: strengthening mainframe systems and applications, and reducing outages. So, in this edition, we thought we'd talk about some resilience issues that, well, people often don't talk about.

As assembler programmers, we love using eyecatchers for data areas. We talk more about how this can improve the resilience of any program in our first technical article. In our second, we look at options when we're modifying code that is really, really bad.

In our opinion article we argue that change management is good, change management that is too heavy is bad, and counter productive.

In November, we presented at the Perth Z Community Event, discussing some of the z/OS resilience features we see unused, or under-used.

Finally, at TechChannel, we look at five ways to quickly speed up batch jobs.

We hope you enjoy this issue.
