Each of these regions displays a transaction counter in its logs unique to itself, but you want to get a global view of the transactions, meaning you want to see how each region is doing individually compared to the others as well as what the current global transaction count is. You have a workload with one piece replicated to three z/OS jobs, each running in a unique region spread across three z/OS LPARs. Imagine you are an application developer or a system programmer. Problem Statementīefore delving into the pros, cons, and differences between Zowe and ZOAU, I’d like to first offer a use case for which we can refer to for this blog. Since covering every available tool would take considerable time not only for me to research but for you to read about, I would like to offer a comparison of two of my favorite, and still relatively new tools: Zowe and Z Open Automation Utilities or ZOAU. In this blog post, I hope to offer some insight on which tools will best meet your goals. In my opinion though, it can sometimes be difficult trying to decide which tool is the best choice to use. The myriad of tools we young folks have available is great in that it allows us to choose, and in some cases even build a solution to, how we interact with the mainframe. In a time where more early-tenured software engineers and computer scientists are working on the mainframe than at any recent point, this is certainly a good problem to have. ![]() What’s worse, is that when folks explain or demonstrate these tools to their peers, it seems that they often get feedback that “this is nothing new” or “such and such a tool does (or used to do) the same thing.” Again, I find this both troubling and amazing at the same time. It seems like every day (OK maybe that’s a stretch, let’s just say “relatively frequently”) there is a new tool from a new area that offers a modern interface or method to interact with z/OS. I see this as both a blessing and a curse, and it’s something that has been in the back of my mind for quite some time now. Today, it seems that there is no shortage of modern methods of interacting with z/OS.
