The SQL Counts (3) workspace provides information about
currently committed rows, multi-row processing, workfile storage,
and concentrate statements.
This workspace is comprised of the following views:
- “Use Currently Committed” shows, for the
selected thread, the number of rows for currently committed data that
is skipped or accessed by read transactions when processing a DB2® application.
- Multi-Row Processing enables you to track
performance improvements such as multi-row fetch and multi-row insert.
- Workfile Storage shows the statistics on
the usage and storage of DB2 workfiles.
- Concentrate Statements indicates if literal
constants, which are referenced in dynamic SQL statements, are replaced
with special markers so that these constants are not cached with the
statement in the dynamic SQL statement cache.
Based on the information that this workspace provides,
you can recommend changes, set up situations, and verify that your
recommended changes improve system performance.
