n is either 1 (true) or 0 (false).
When this parameter is enabled (n = 1), InterSystems IRIS® data platform enables the ECP service (%Service_ECP) during instance startup. When EnableECP is disabled (n = 0), %Service_ECP is unchanged during instance startup. This means EnableECP can be used only to enable the ECP service, not to disable it.
EnableECP is not in the default CPF, but can be included as a parameter in a CPF merge file. To directly enable %Service_ECP without the EnableECP parameter, use the Services page of the Management Portal (System Administration > Security > Services).
Changing This Parameter
EnableECP is not in the default CPF. You can manually add this parameter to the [Startup] section of the CPF using a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
After adding EnableECP and restarting InterSystems IRIS, you can change the parameter using a text editor, the Config.Startup class (as described in the class reference), or the Startup page of the Management Portal (System Administration > Configuration > Additional Settings > Startup).
