n is an alphanumeric string. The default is an empty string.
SystemMode defines a label that appears in the Management Portal header. This label can be used to easily identify an instance of InterSystems IRIS® data platform. For example, you could label a production system “LIVE,” or a test system “TEST.”
Changing This Parameter
On the Startup page of the Management Portal (System Administration > Configuration > Additional Settings > Startup), in the SystemMode row, select Edit. Enter the desired label in the SystemMode text box.
Instead of using the Management Portal, you can change SystemMode in the Config.Startup class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
CPF Parameters in the “ICM Reference” chapter in InterSystems Cloud Manager Guide.
