It's less overhead to have a permanent STC on each LPAR and use a MODIFY command for change notification.

There're different ways, Sysplex Services (other guys already mentioned) or developing a STC that runs on every LPAR listening to IP stack. The problem is (and always will), how to be sure all the LPARS got, understood and refreshed the needed infos. If you want to simplify sending commands starting STCs on every LPAR, you could use an operator interface (IBM, Broadcoam, BMC, your own). You can issue a WTO and let the automated-operator to send the needed command to all the LPARs (RO *ALL). This should avoid the APF auth at your programming level. Regards.
