Oracle ORA-12514 解决办法

1. 找到listener.ora监听文件，具体位置如：

C:appAdministratorproduct11.2.0dbhome_1
etworkadminlistener.ora

2. 在lisener.ora文件中添加下方加红加粗部分：

# listener.ora Network Configuration File: C:appAdministratorproduct11.2.0dbhome_1
etworkadminlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:appAdministratorproduct11.2.0dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:appAdministratorproduct11.2.0dbhome_1inoraclr11.dll")
    )
    (SID_DESC = 
      (GLOBAL_DBNAME = ORCL) 
      (ORACLE_HOME = C:appAdministratorproduct11.2.0dbhome_1) 
      (SID_NAME = ORCL) 
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-UBKOOK0BP2K.geostar.com.cn)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = C:appAdministrator

3.相同目录下tnsnames.ora文件内容如下，参考使用：

# tnsnames.ora Network Configuration File: C:appAdministratorproduct11.2.0dbhome_1
etworkadmin	nsnames.ora
# Generated by Oracle configuration tools.

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

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-UBKOOK0BP2K.geostar.com.cn)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

4、重启服务

1). 先停监听，后停实例。
2). 先起实例，后起监听。
