You can activate the license for InfoSphere® Optim™ Query Workload Tuner by running a JCL job, if you do not want the license to be activated automatically by the IBM® Data Studio full client.
A product license must be active on each DB2® for z/OS® subsystem that you connect to through the client when you are tuning queries and query workloads.
When you connect to a DB2 for z/OS subsystem from the IBM Data Studio full client and the license activation kit is installed with the client, the client detects whether a license is not yet present on the subsystem. If a license is not present, the client installs and activates the license.
If you would rather activate the license manually on a subsystem, you can run a JCL job that is included in the installation directory for the client after you install the license activation kit.
