De-Mystifying the High Performance DBAT with John Campbell
Jul 16, 2025
Julia Carter & Marcus Davage for IDUG

After hearing John Campbell speak at GSE Nordic 2025, Marcus had questions...What is a high-performance DBAT? How do you make a thread "high performance"? 

John Campbell – Db2 guru, consultant, and former IBM Distinguished Engineer  – starts at the beginning of the distributed journey within Db2 for z/OS. Tune in to learn about cheap connections vs expensive threads, whether a large or small connection pool is better, and the really stupid default in an early Db2 Connect fix pack. Truly an enjoyable conversation (that even our non-technical marketing team could follow).
