Excerpt below from last two articles, which is important to me.
$ $JAVA_HOME/bin/java -jar ords.war configdir /u01/ords/conf

INFO: Set config.dir to /u01/ords/conf in: /u01/ords/ords.war
$
Configure ORDS using the following command. This is the equivalent of specifying the "install simple" command line parameters. Make sure you agree to configure the PL/SQL Gateway and not to enable "standalone mode".
Auto SSL (HTTPS)
ORDS will automatically create a self-signed certificate for use with SSL if you don't specify a valid certificate and key.
Edit the "/u01/ords/conf/ords/standalone/standalone.properties" file, setting the following parameters. Adjust the port as desired.
jetty.secure.port=8443
ssl.cert=
ssl.cert.key=
ssl.host=
Restart ORDS.
