You must enable certain facilities and objects on a DB2® database or subsystem before
you can use the no-charge tuning features to tune the SQL statements
that run on that database or subsystem.
If you want to tune SQL statements with the full set of
tuning features, you must activate a license for IBM® InfoSphere® Optim™ Query Workload Tuner on the DB2 databases or subsystems that
you work with.
For a comparison of the features that are supported
in Data Studio with the features that are supported in InfoSphere Optim Query
Workload Tuner, see Tuning features by product.
