I installed oracle database 11g enterprise edition to my laptop. When I was installing oracle, at the beginning I selected Desktop Class (not server class) option.
Now I am trying to make remote connection to my Oracle database from another PC but I cannot connect to Oracle and get this error message:
"ORA-12545: Connect failed because target host or object does not exist"
even though all Oracle services have been already started.
May the reason be why I installed Oracle as desktop class instead of server class?
