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 the full set of tuning features 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.
