Listener refused the connection with the following error: ORA-12514, TNS:listener does not currently know of service requested in connect descriptor.oracle

緣由：監聽器配置問題，具體沒搞懂，猜想是SID連接不匹配，監聽器沒法監聽到orcl。app

修改oracle安裝目錄下D:\app\xuannan\product\11.2.0\dbhome_1\network\admin\listener.ora文件spa

# listener.ora Network Configuration File: D:\app\xuannan\product\11.2.0\dbhome_1\network\admin\listener.ora

SID_LIST_LISTENER =

(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\app\xuannan\product\11.2.0\dbhome_1\bin\oraclr11.dll")

加上這一段就行了配置
