3、數據庫無監聽程序解決方法

先查看服務是否開啓 services.msc

找到該目錄地址：app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN

1、用記事本打開文件tnsnames.ora
新增如下內容

ORCLTEST =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 計算機名)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ORCLTEST)
    )
  )

其中(ADDRESS = (PROTOCOL = TCP)(HOST = 計算機名)(PORT = 1521))
修改HOST的參數
#有網HOST=127.0.0.1
#無網HOST=計算機名

#有網用計算機名可能也行，未驗證

2.記事本打開文件listener.ora
新增如下內容

LISTENERTEST =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = PC-20160205BPRE)(PORT = 12580))
    )
  )
