OracleDB TNS侦听器配置

Question

我想在我的计算机（win 8.1）上配置OracleDB18c，但侦听器配置有问题...

我想与我的计算机（localhost）上名为ORCL的数据库连接，但是尝试配置侦听器失败（尽管我通过SQL * Plus建立了连接）

这是我的配置文件：

listener.ora

# listener.ora Network Configuration File: C:\Users\User\Desktop\oracleDB\NETWORK\ADMIN\listener.ora

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\Users\User\Desktop\oracleDB)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\Users\User\Desktop\oracleDB\bin\oraclr18.dll")
    )
    (SID_DESC =
      (GLOBAL_DBNAME = orcl.localhost)
      (SID_NAME = ORCL)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =

    )
  )

      (PRESENTATION = RO)
    )
  )

    )
  )
