ORA-12541: TNS: 無監聽程序

虛擬機安裝oracle報錯：ORA-12541: TNS: 無監聽程序    ，（每個人遇到的問題不一樣，具體看是否適用）,不建議安裝本機oracle

具體和三個文件有關，listener.ora（監聽）    sqlnet.ora   tnsnames.ora(監聽實例?),具體例子可到C:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\SAMPLE 中複製修改

原始文件

回退一布文件夾中的內容

tnsnames.ora 需要修改的內容 監聽ip地址，端口，實例名稱

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.80.10)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

listener.ora 如下 oracle_home的環境變量配置SID 以及listener 的TCP的ip和端口

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oracle\product\10.2.0\db_1)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.80.10)(PORT = 1521))
    )
  )
 

sqlnet.ora 具體如下

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

 

用你的instantclient 連接試試 ，注意實例名稱不要錯，就是安裝oracle的用戶名稱

D:\soft\instantclient_12_1>sqlplus system/[email protected]:1521/orcl
