IDUG NA 2026

Even well‑written SQL can slow Db2 for z/OS when subtle mistakes slip through. In this hands‑on lab, attendees will work with preloaded queries that showcase common pitfalls—over‑indexing, missing or stale statistics, inefficient joins, unnecessary sorting, and predicate mismatches. You’ll identify the issues, apply targeted fixes, and validate improvements using metrics, access path analysis, and supporting tools.
Beyond immediate speedups, this lab reinforces a repeatable diagnostic approach that strengthens day‑to‑day tuning and sets the stage for AI‑assisted operations—where consistent, high‑quality data enables smarter automation and more reliable outcomes.
