Using dynamic enablement

As explained in Learning about z/OS, the priced features support dynamic enablement. This means that the priced features that you order are shipped enabled and are ready to use after you install and customize them. The priced features that you do not order are shipped disabled; even though you install them, you cannot use them. Later on, if you decide to use them, you enable them dynamically.

While priced features are the main focus of dynamic enablement, several related items can also be dynamically enabled should you decide to use them with z/OS®:

The individual product versions of z/OS nonexclusive features.
The product Document Composition Facility (DCF) (5748-XX9).
IP Services, one of the components of base element Communications Server, which is shipped enabled when you order the standard z/OS base but disabled when you order the alternate base configuration. Note that "TCP/IP" is the name used for dynamic enablement of this component.

Note: Infoprint Server Transform products V1 (5697-F51) was removed from the list when service support ended. The follow-on Infoprint transform products have not been added to the list because they are not dynamically enabled.

In brief, the steps required to dynamically enable are:

Notify IBM® that you are starting to use the feature, product, or TCP/IP on a specific processor (as identified by a specific processor serial number).
Update parmlib. IBM supplies a SYS1.PARMLIB member, IFAPRD00, that is tailored to your order. IFAPRD00 contains entries that enable the priced features, products, or TCP/IP that you ordered for a specific processor. To make the parmlib update, copy the contents of IFAPRD00 to an IFAPRDxx member that will be active on the processor for which your z/OS order was placed, and modify IFAPRDxx appropriately.
Establish the active parmlib member through the PROD parameter in IEASYSxx or the SET PROD operator command.
