SQL/MP Program Overview (SQLPROG)
SQL/MP Program Overview (SQLPROG)
This 76-column chart provides an overview of SQL/MP programs. It is sorted by
descending elapsed busy time (summed over all SQL/MP statements executed by all
processes run from each program file name) so the program objects that spent the
longest time waiting for SQL/MP statement executions are at the top of the list. This
chart includes:
•
Program file name
•
Program’s overall selectivity (total records used divided by total records accessed,
expressed as a percentage
•
Flags for nonzero sorts, recompiles, lock waits, timeouts, and escalations
•
Program’s individual share of total elapsed busy time
•
A chart of the preceding share
•
Cumulative share of total elapsed busy time
This chart uses the GLOBINFO, SQLTOTAL, and PROGSQL entities.
Parameters used are:
•
LID—specifies the Measure Load ID
•
SECTION—specifies the report section number
The chart is sorted in descending elapsed busy time.
