Do you run REORGS on a fixed schedule or when certain statistics thresholds are reached? Are they actually helping your applications? This session will explore techniques for correlating real I/O performance to the need for pageset reorganizations. There are potentially savings to be had if REORGS are only done when needed, which might be much less than you think.

Identify object and application triggers that help identify objects in need of reorganization
Establish a process for identifying application pagesets for analysis
Identify I/O performance trends for DB2 pagesets
Correlate reorganization benefits to I/O performance trends
Understand the best methods for collecting I/O performance data
