The third component in OCS is called Event Management Logger. Event Management logger also runs as daemon process ‘evmd’. The daemon process ‘evmd’spawns a permanent child process called ‘evmlogger’ and generates the events when things happen. EVMD child process ‘evmlogger’ spawns new children processes on demand and scans the callout directory to invoke callouts. It will restart automatically on failures and death of the evmd process does not halt the instance. Evmd runs as ‘oracle’ user.
