ssl connection for RJDBC

[joepowers16]

My company is instituting an ssl requirement soon for database connections.

I previously connected to our Vertica database via DBI and RJDBC packages. I have tried adding an sslmode='require' parameter to my connection. But adding this parameter has no effect. I can still connect to the database but the connection is not ssl.

Can anyone advise on how to enable ssl connection for DBI? In Pycharm I merely had to set ssl to true in the driver properties.

DBI::dbConnect(
	drv = RJDBC::JDBC(
		driverClass = driver_class,
		classPath = class_path
	),
	url = url,
	UID = user_id,
	PWD = password,
	sslmode = 'require'
)
}

A different ssl parameter was required. I am having connection success with the function below that uses ssl = 'true'

	DBI::dbConnect(
		drv = RJDBC::JDBC(
			driverClass = driver_class,
			classPath = class_path
		),
		url = url,
		UID = user_id,
		PWD = password,
		ssl = 'true'
	)
