TNS-12514：TNS：偵聽器當前不知道連接描述符中請求的服務4/2016

我在嘗試從SQL Developer或Net Manager連接到新安裝的Oracle Enterprise時出現此錯誤。我嘗試了所有我找不到的解決方案。TNS-12514：TNS：偵聽器當前不知道連接描述符中請求的服務4/2016

我想連接一個系統帳戶，並且能夠使用sqlplus登錄，所以我知道我的憑據是正確的。

的listener.ora

SID_LIST_LISTENER = 
    (SID_LIST = 
    (SID_DESC = 
     (PROGRAM = extproc) 
     (ENVS = "EXTPROC_DLLS=ONLY:C:\Oracle\OracleUser\product\12.1.0\dbhome_2\bin\oraclr12.dll") 
     (SID_NAME = CLRExtProc) 
     (ORACLE_HOME = C:\Oracle\OracleUser\product\12.1.0\dbhome_2) 
    ) 
) 
LISTENER = 
    (DESCRIPTION_LIST = 
    (DESCRIPTION = 
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) 
    ) 
    (DESCRIPTION = 
     (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) 
    ) 
) 

ADR_BASE_LISTENER = C:\Oracle\OracleUser\product\12.1.0\dbhome_2\log

的tnsnames.ora

LISTENER_ORCL = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) 

ORACLR_CONNECTION_DATA = 
    (DESCRIPTION = 
    (ADDRESS_LIST = 
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) 
    ) 
    (CONNECT_DATA = 
     (SID = CLRExtProc) 
     (PRESENTATION = RO) 
    ) 
) 

ORCL = 
    (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) 
    (CONNECT_DATA = 
     (SERVER = DEDICATED) 
     (SERVICE_NAME = orcl) 
    ) 
)

它使我困惑，而不是'系統'Oracle帳戶，錯誤是列出我的Windows登錄帳戶（my_wind ows_login）。

請指教！

看來你有兩個oracle家園。

檢查cmd的輸出 - >tnsping orcl命令。您可以看到正在使用哪個oracle目錄。

然後您可以檢查環境變量 - >系統變量 - >路徑並重新排序Oracle主目錄。這工作在我的情況。
