Issue/Introduction
What are the causes for high Db2 GETPAGE activity captured by Detector for Db2 for z/OS?
Environment
Release: 20.0 Component: PDT
Resolution
High GETPAGE activity means that Db2 is reading a lot of pages to satisfy SQL requests. This generally points to an index tuning opportunity or the fact that RUNSTATS may not have been run causing Db2 to choose the wrong access path to the data.
