자세한 답변 정말로 감사드리고요.. 한가지만 더 질문 드릴께요.

제가 자바에서 접속을 할때

String url = "jdbc:oracle:thin:@localhost:1521:orcl"; //oracle 로 하면 안되요.

Connection con = DriverManager.getConnection(url,"scott","tiger");

이렇게 해야만 접속이 되거든요. 근데 저의 listener.ora 하고 tnsname.ora 의

SID 명을 oracle 로 했거든요. 근데 위의 @localhost:1521:orcl";에서

oracle 로 하면 안되는데.. 상관이 없는건가요.

설치 할때 global database name 을 oracle 로 했는데..

감사합니다.
