SOA 12c Database EM is not accessible in the browser

Assumption: Database 12c is installed successfully on your local VM.

After successful install of Oracle Database 12c and starting the Listener and the Database, you might notice that the EM is not accessible in the Firefox by typing https://localhost:5500/em/login,

You will see this issue only if you are running the database on Linux VM and trying to access the EM in the Linux Firefox. The initial login EM page requires Flash plugin. Usually, on the Linux based VM's the flash is not installed and you cannot bring up the login page.

You can try to access the EM from the host machine by typing https://<VM Machine Name>:5500/em/login and the page should come up if the Flash plugin is installed and the Database and Listener are running.

I hope this will help to resolve the issue if you happen to encounter one.
