To dynamically activate the updated enablement policy without an IPL, place the updated PRODUCT statements in the appropriate IFAPRDxx member of the active SYS1.PARMLIB data set. You can then issue the SET PROD operator command to specify the IFAPRDxx member that defines the enablement policy. See z/OS MVS System Commands for more information.

The enablement policy change takes place immediately but does not affect any instances of features, products, or TCP/IP that are already executing. Also, activating a new enablement policy does not start any of the enabled features, products, or TCP/IP. They will only run when explicitly started by some other action, such as a START command.

Be sure to change the PROD system parameter in IEASYSxx to point to the appropriate IFAPRDxx member; no IFAPRDxx member is activated by default. This change ensures that the next IPL activates the correct policy. For more information about using IFAPRDxx, see z/OS MVS Initialization and Tuning Reference.
