Hi Steff,
Have the application which updates the data put out a WTO which triggers your Automation to schedule Tasks on all other LPARs (e.g. RO *ALL, S UPDATE).

We have global data pointed to by a name-token that is available to all the
address spaces in each computer system.  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?

Thanks,
Steff Gladstone
