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.
