I know this error has already been intensively discussed in this thread here: Resolving port 5500 not free issue during Oracle 12c Release 2 Database Configuration Assistant installation on CentOS
However, despite the solutions proposed I can't install Oracle 12c on CentOS 7.
I skiped the Database Configuration Assistant during standard installation process in order to run it again using Xming. There it is possible to enter the
EM database express port manually.
I tried almost any port number, I always get the error message shown in the screenshot.
Do you have any suggestions what else I could do?
