Oracle XE 11g2에 연결할 수 없습니다

Question

이것은 2 일 동안 나를 미치게했습니다. 필자는 최근에 localhost (Windows 7 Enterprise)에 Oracle Express Edition 11g2를 설치했습니다. 데이터베이스와 수신기를 시작할 수는 있지만 연결할 수 없습니다.

나는 다음과 같은 매개 변수를 사용하여 SQL Developer에서 연결을 시도 :

Username: SYSTEM 
Password: *********** 
Hostname: localhost 
Port: 1521 
Service name: XE 

나는 다음과 같은 오류 얻을 : An error was encountered... IO Error: The Network Adapter could not establish the connection. Vendor code 17002 분명히 SQL 개발자가 ORA-12541: TNS no listener에 대한 이야기입니다.

내가 SQL 명령 줄에서 연결을 시도

은 :

SQL> connect 
Enter user-name: system 
Enter password: 
ERROR: 
ORA-12638: Credential retrieval failed 

내 ORACLE_HOME은 C:\oraclexe\app\oracle\product\11.2.0\server로 설정됩니다.

리스너 시작은

SQLNET.AUTHENTICATION_SERVICES = (NTS) 

잘 작동하는 것 같다 인터넷 검색의 solutio에 이르지 못했습니다 n ...

Answer 1

리스너 및 TNSNAMES 파일에서 LOCALHOST 대신 IP 주소 127.0.0.1을 사용하십시오.

수신기를 다시 시작하고 다시 연결하십시오.
