Fast copies of Db2 for z/OS tables are increasingly difficult as newer features add structural complexity. Table versioning, partition growth and rotation, XML and LOB data, temporal and archive relationships, and deferred VSAM creation can prevent direct dataset-level copies and force slower fallback methods. This webinar explains the key challenges and what they mean for copy speed and reliability.

Efficient data extraction is critical for analytics, migrations, and modern application integration. Optim High Performance Unload (HPU) provides a powerful, flexible, and lightning-fast way to unload Db2 data without impacting production workloads. This session will explore how HPU can be used for faster unloading and migrating data by using direct access methods to deliver unmatched performance compared to traditional unload utilities. In addition, we will demonstrate how HPU can recover data directly from backup images in the event of table loss, ensuring business continuity and minimizing downtime. Attendees will learn best practices for optimizing unload tasks, and handling large-scale migrations to cloud or hybrid environments. Real-world case studies will highlight performance gains, reduced disk space consumption, and simplified operations. Whether you are a DBA, or architect, this session will equip you with practical strategies to maximize the value of HPU in your enterprise.

This 4 hours workshop - knowledge transfer session will be conducted by following presenters: Toine Michielse, Michal Bialecki, Emil Kotrc, Denis Tronin
In the world of Db2 for z/OS, "set it and forget it" is a recipe for performance degradation and wasted storage. As data volumes explode and batch windows shrink, traditional housekeeping—REORG, RUNSTATS, and IMAGE COPY—must evolve from manual chores into a streamlined, automated strategy.
This deep-dive workshop provides a comprehensive blueprint for modern Db2 maintenance. We will move past the basics to explore how to balance object availability with optimal performance. Attendees will learn how to leverage the latest utility enhancements to reduce CPU consumption, manage multi-terabyte objects, and ensure that the optimizer always has the "ground truth" through intelligent statistics collection.
