When Studio's outward-facing port is configured securely (with reverse proxy), the plug-in uses the same port to also connect to Studio in secure mode.
To establish a secure connection, you need to provide the plug-in with the SSL Keystore/Trust Keystore information.
Before installing Big Data Discovery, you can configure options in bdd.conf for a secure installation of Studio within WebLogic Server. For information, see the Installation and Deployment Guide. That guide also describes how you can set up Studio to use a reverse proxy, after the installation.
If Studio is not deployed securely, the Guided Discovery process of the plug-in determines this fact and does not let you provide SSL information during target discovery process in the plug-in. In such cases, to make sure that the plug-in uses the secure port for Studio in BDD 1.0, you should manually provide information about SSL for a Studio target in the plug-in by setting the monitoring credentials. For information on setting monitoring credentials within Enterprise Manager plug-in, see https://docs.oracle.com/cd/E24628_01/doc.121/e36415/sec_features.htm#sthref208 in the Enterprise Manager Cloud Control Security Guide.
