I am curious to know if anybody has found a good way to "replicate" event posting across IOCs. I am thinking about utilizing CPP flags, but not sure if that is a good solution.


If you can tolerate latency, each IOC can have its own event record. One IOC hosts a trigger record which can then use CA links to trigger processing of each of these event records (e.g. fanout, CP/CPP links, etc.). If you cannot tolerate the latency or need real-time performance, a hardware-based timing system is typical.
