During installation, the Oracle FS System vSphere Plug-In generates a self-signed certificate used to secure traffic between the vSphere Client and the vCenter Server.
The Common Name (CN) used for both the issued to and issued by parts of the certificate will match the vCenter Server name or IP address. Since these portions of the field are generated locally, they will not match the list of trusted issuers used by the browser embedded in the vSphere Client. Therefore, when you view the Oracle FS System tab or select a Manage Oracle FS System Storage Management task, a Security Alert dialog appears indicating the certificate is not trusted.
The certificate must be trusted in order to use the Oracle FS System vSphere Plug-In. When the Security Alert dialog appears, you must click Yes to indicate that you trust the certificate. This indicates that you trust the certificate for the current session only. You can install the certificate in a trusted certificate store to keep this dialog from appearing each time you start the vSphere Client to use the plug-in.
