If this was my code, I would be using one of : (o) IXCNOTE (o) IXCSETUS with XCF groups (o) IXCSEND/RECV
All the above are really easy to code and built for exactly this sort of thing. If you absolutely must use problem state code, then a couple of ideas : (o) SYSTEMS scope ISGENQ with USERDATA with servers in periodic wakeup to issue ISGQUERY to check the contents of the USERDATA to see if changed. (o) TCP/IP sockets (so many error codes to consider and recover from...)

Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] 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?
