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).
In brief, the steps required to dynamically enable are:
  1. 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).
  2. 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.
  3. Establish the active parmlib member through the PROD parameter in IEASYSxx or the SET PROD operator command.
The rest of this section helps you decide whether you need to use dynamic enablement, describes in detail the three steps to do it, and explains how to disable should you want to. Topics are:
