Question

尝试从SQL Developer或Net Manager连接到新安装的Oracle Enterprise时出现此错误。我确实尝试了所有我找不到的解决方案。

我正在尝试连接系统帐户，我可以使用sqlplus登录，所以我知道我的凭据是正确的。

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)
    )
  )

在<\ product \ 12.1.0 \ dbhome_2 \ log \ diag \ tnslsnr \ iper410a \ listener \ trace \ listener.log

内的

TNS-12514: TNS:listener does not currently know of service requested in connect descriptor

让我感到困惑的是，而不是系统＆＃39; Oracle帐户，错误是列出我的Windows登录帐户（my_windows_login）。

请指教！

看来你有两个甲骨文家园。

检查cmd的输出 - ＆gt; tnsping orcl命令。您可以看到正在使用的oracle目录。

然后你可以检查环境变量 - ＆gt;系统变量 - ＆gt;路径和重新排序Oracle主目录。这适用于我的情况。
