ORA-12505, brak połączenia z bazą

Question

Cześć,

Na wstępie zaznaczę, że jestem lakiem jak chodzi o SQL.
Mam problem z połączeniem się z bazą danych, ponieważ wyskakuje mi komunikat:

"An error was encountered performing the requested operation:
Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
Vendor code 12505"

Listener status:

C:\Windows\system32>lsnrctl status

Usługi:
OracleXETNSListener - działa
OracleXEClrAgent - działa
OracleServiceXE - działa
OracleMTSRecoveryService - nie działa "system windows nie może uruchomić usługi OracleMTSRecoveryService na komputer lokalny. Błąd 3: System nie może odnaleźć określonej ścieżki"

 

Próbowałem szukać rozwiązania, ale albo nie umiem rad zastosować, albo nie działają...

Któś wie, co może być nie tak? :(

 

Answer 1

A jakiego SID / SeviceName wpisujesz w trakcie logowania ?.

Możesz wykonać polecenie TNSPING na tę nazwę i zobaczysz czy jest ona dostępna.

SID: xe

Z TNSPING otrzymuję:
