When i tried to start EM dbconsole got this “ERROR http: 14: Unable to initialize ssl connection with server, aborting connection attempt” in emagent.trc file. Then i realized that EM certificate is expired. You can check EM certificate state from any browser’s (IE, Mozilla etc.) security report. All you need is just “emctl secure dbconsole” command.
$ emctl secure dbconsole
TZ set to Turkey
