Oracle Error :ORA-12514:TNS：监听程序当前无法识别连接描述符中请求的服务的解决办法

ORA-12514的解决办法

报错信息：
ERROR:
ORA-12514: TNS：监听程序当前无法识别连接描述符中请求的服务的解决办法

解决办法：
搜索“listener.ora”文件，并且以txt的形式打开，增加一下内容：

(SID_DESC = 
        (GLOBAL_DBNAME = orcl)
        (ORACLE_HOME = F:\app\Dell\product\11.2.0\dbhome_1)
        (SID_NAME = orcl)
    )
//其中，ORACLE_HOME那里应该是你自己电脑上面Oracle安装的所在位置，
//要根据自己的情况进行修改

修改好，我的listener.ora文件所长的样子：

# listener.ora Network Configuration File: F:\app\Dell\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = F:\app\Dell\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:F:\app\Dell\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
    (SID_DESC = 
        (GLOBAL_DBNAME = orcl)
        (ORACLE_HOME = F:\app\Dell\product\11.2.0\dbhome_1)
        (SID_NAME = orcl)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )
