n is either 1 or 0. The default value is 0.
When JDBCGatewayUsePassphrase is enabled (n = 1), a passphrase is required for JDBC connections from InterSystems IRIS to external applications. The instance generates a new passphrase each time it starts the JDBC Gateway. Applications running inside an InterSystems IRIS instance that use the JDBC Gateway automatically include the appropriate passphrase, as needed, when connecting to the gateway.
When JDBCGatewayUsePassphrase is disabled (n = 0), a passphrase is not required.
Changing This Parameter
On the JDBC Gateway Server page of the Management Portal (System Administration > Configuration > Connectivity > JDBC Gateway Server), select Use Passphrase to require a passphrase.
You can also change JDBCGatewayUsePassphrase with the Config.SQL 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).
