Once all major bugs and performance deficiencies have been removed and once the
benchmark implementation has been audited, the final tuning and the formal measurements
can take place.
The final tuning usually consists of finalizing the layout of the database on the
available storage subsystem and fine-tuning the various
DBMS and OS parameters.
Last minute bugs may also be discovered and may have to be corrected at this stage.
Because the implementation has already been audited, no major changes can be made
to the benchmark kit without having to repeat the pre-audit.
Once the target performance has been reached, a fresh new database in built and
the formal measurements begin. The audited procedures are followed and the audited
scripts are executed. The results of all the measurement tests are captured into
predefined audit files, ready for the final audit.
