Many Db2 DBAs treat the z/OS Workload Manager (WLM) as "the system programmer’s problem," but WLM is actually the engine that determines if your SQL succeeds or fails. In this session, we will demystify WLM from a DBA’s perspective. We’ll cover the basics: defining service classes, importance, and goals. You will learn how WLM distinguishes between "local" work (like batch) and "remote" SQL (using enclaves), and why this matters for your daily performance monitoring. We’ll wrap up with simple best practices and a look at how to spot WLM issues before they become outages. Join this session to learn how to speak the language of WLM and ensure your Db2 workload gets the priority it deserves.
