How Operator Messages Are Created
The Event Management Service (EMS) is a set of processes that collects event messages
from reporting processes and subsystems. The EMS primary collector process ($0) is the
primary collection point for these event messages. $0 collects messages generated by
reporting subsystems and writes these messages to an event log file.
The event log file is read by the EMS distributor processes configured onto or started on
your system. The distributor processes then send messages to various destinations.
The $Z0 compatibility distributor can be configured only in EMS mode. It formats event
messages from the event log file into operator messages and distributes them to the local
operator console.
