DB2 graphic QMF Version 8

Query Analyzer

The Query Analyzer provides preemptive governing capabilities. It traps queries before they are processed by DB2 and estimates their resource consumption. Queries that are judged too intensive can be canceled before they run. This facility can only be activated for QMF/TSO sessions.

Note:
When running QMF under TSO, QMF looks for a governor module named DSQUEGV1. When running QMF under CICS, QMF looks for a governor module named DSQUEGV3. The HPO/Governor modules and the QMF sample governor modules have the same name. "Step 4.b Special allocations for the HPO/Governor module," explains what is necessary to ensure that QMF finds the HPO/Governor modules instead of the sample governor modules.
