Speaker Bio: Senior Manager and Senior Software Engineer with IBM DB2 LUW development, responsible for multiple core DB2 kernel components. Always thrilled to work on hard-to-crack puzzles. Expertise in DB2 LUW kernel architecture, configuration and administration, advanced problem determination, memory architecture, memory leak troubleshooting, and assembly language. Hands-on development experience with buffer pool management, storage, prefetching, page cleaning, transaction logging, recovery, monitoring, and problem determination. As a member of the DB2 team, Pavel spent years in DB2 L2/L3 advanced support (over 1,500 resolved cases), then transitioned to DB2 LUW kernel development. In his past life Pavel was an application developer mostly using C++, SQL, .NET, Oracle, MS-SQL, and Informix on Windows, Linux, Solaris, and HP-UX.

Abstract:  DB2 storage de-mystified. DMS, SMS, Automatic Storage table space internals. Default table space types across different DB2 editions and versions. Best practices. Container structure, naming conventions, internal architecture. Buffer pool considerations. Storage paths, auto-extend mechanisms, automatic striping. Parallelism vs. performance discussions. Common high watermark issues, reclaimable (object-relative) vs. non-reclaimable (pool-relative). Explanation on current deprecation statements, upgrade paths and considerations. Common tooling and tricks to deep dive into the storage components (db2dart, db2pd, and others).
