Enable/disable writing of InterSystems IRIS system error log entries (see InterSystems IRIS System Error Log in the Monitoring InterSystems IRIS Using the Management Portal chapter of the Monitoring Guide) to the messages log file on shutdown.
This setting controls InterSystems IRIS behavior during execution of its SHUTDOWN procedure. The value n may be 1 or 0:
When 1 (true) during shutdown InterSystems IRIS logs error information from the InterSystems IRIS system error log into the messages log file (that is, messages.log in the InterSystems IRIS system management directory, or the alternate filename.log named by the second piece of the console parameter).
