n is the name of a license key in the target .key file. By default, no key is specified.
If InterSystems IRIS® data platform does not detect a local iris.key file at instance startup, it uses LicenseID to request a license key from the License Server. Each license key loaded in the License Server will have a unique LicenseID.
For more information about license keys, see the Managing InterSystems IRIS Licensing chapter in System Administration Guide.
Changing This Parameter
On the Startup page of the Management Portal (System Administration > Configuration > Additional Settings > Startup), in the LicenseID row, select Edit. Enter a LicenseID.
Instead of using the Management Portal, you can change LicenseID 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).
