This session will share experience from client studies and engagements: sharing proven recommended best practice; learning good, bad and ugly; providing answers ti important, frqeeunt or difficuly questions. This session will cover the following topics: Complacency about component failure and ability to absorb workload failover in a dat asharing environment; missed opportinity for elapsed time performance improvementnfor skip sequnetial batch processing; misteps in evaluating the performance benenfit of CICS-Db2 thread reuse and RELEASE(DEALLOCATE); SQL coding to avoid update anomaly when using cursor stability isolation; misadventures when using High Performance DBATs;monitoring WLM policy achievement; options for mass data recovery following logical data recovery and data loss; performance issue with remote DDF batch workload; tuning ogf GBPs; thorough Disaster Restart testingh.

Recovery is only as good as the backup that fuels it. While "taking an Image Copy" is a daily routine for every DBA, understanding the internal mechanics of that process is critical for modern data resilience. In this session, we go beyond the syntax to explore the physics of Db2 data protection.We will dissect the copy process showing how the choice of backup type directly dictates recovery performance.
