Note the following when using the IFAPRDxx member:
You can use the SET PROD operator command to modify the enablement
policy dynamically by specifying which IFAPRDxx member(s) the system
is to use. Statements in the member(s) modify, not replace, an existing
policy.
The change to the policy takes place immediately but does
not affect any product instances that are already running.
The system does not automatically list the IFAPRDxx parameters
at IPL or when the operator issues SET PROD, but the operator can
issue the DISPLAY PROD,STATE command to display the active enablement
policy.
