Db2 for z/OS Data Sharing: configurations and common issues  Mark Rader IBM

Abstract: Db2 for z/OS Data Sharing has been available for over 25 years. Many IBM clients rely on Db2 Data Sharing for their production systems to provide continuous availability, flexible scalability, and workload balancing to their critical applications. This session briefly reviews Parallel Sysplex components, describes basic data sharing configurations, and discusses common issues, including considerations for Db2 coupling facility structures: shared communications area (SCA), lock structure (LOCK1), and group buffer pools (GBPs).

“Identify Hidden Insights using Db2 13 SQL Data Insights” Akiko Hoshikawa IBM

Db2 13 offers an industry’s first embedded AI capability that exploits Db2 data through a simple SQL functions. The session introduces what this innovative capability offers, the technology behind, and more importantly, how you can exploit AI semantic queries using various examples. 

“Db2 13 for z/OS Application Management Enhancements”  Tammie Dang IBM

 Db2 13 for z/OS was recently released last May with several features to support better application management. This presentation focuses on the enhancements with regard to application locking where multiple applications with different characteristics could apply their own priorities, wait time intervals and exist in a multi-tenancy cloud. Enhancements that help to improve object’s online schema change while applications with static SQL are executing concurrently are also discussed.
