Configuring a DB2 for z/OS subsystem for query tuning
You must configure a DB2 for z/OS® subsystem for
tuning SQL statements and workloads by using the InfoSphere Optim™ Query Tuner client or
by running a JCL job on the subsystem. During the configuration process,
you create objects such as tables, table spaces, indexes, and aliases,
bind packages, and enable the stored procedures.
