You could have a VTAM application on each system; I can't think of a simpler way that doesn't require authorization.

We want to make sure that any updates to the data in one system are broadcast to the other computer systems in the installation (LPARs or physical computers). Or at the very least notify the other systems that their data is not up-to-date. What would be the simplest and cheapest way to send some kind of signal from one system to the other without requiring I/O to shared DASD? We thought of issuing a console command starting a started task in each of the other computer systems (the JES2 spool is shared by all the systems.) . But this is problematic since the required SVC (34) requires that the program be authorized. Any other ideas?
