ORA-48108: invalid value given for the diagnostic_dest init.ora parameter

What triggered the Error:

The value given for the diagnostic_dest directory is not a valid directory. Either the directory does not exist or the process does not have read/write privileges on the directory.

Use a value for diagnostic_dest that is a valid directory with the proper read and write privileges.
