ORA 12541 TNS 無監聽程式」錯誤解決

sid_list_listener =

(sid_list =

(sid_desc =

(sid_name = pl***tproc)

(oracle_home = d:/oracle/product/10.1.0/db_1)

(program = extproc)

) )listener =

(description_list =

(description =

(address_list =

(address = (protocol = ipc)(key = extproc))

) (address_list =

(address = (protocol = tcp)(host = pc-***.mail.yyy.cn)(port = 1521))

) ) )

把(address = (protocol = tcp)(host = pc-***.mail.yyy.cn)(port = 1521))

改為(address = (protocol = tcp)(host = 127.0.0.1)(port = 1521))

pc-***.mail.yyy.cn

是計算機名

127.0.0.1

也就是目前資料庫正在用的

ip位址。

4. 檢視

oracle/product/10.1.0/db_1/network/admin/tnsnames.ora

找到下列語句：

orcl =

(description =

(address_list =

(address = (protocol = tcp)(host = pc-***.mail.yyy.cn)(port = 1521))

) (connect_data =

(server = dedicated)

(service_name = orcl)

) )將(address = (protocol = tcp)(host = pc-***.mail.yyy.cn)(port = 1521))

改為(address = (protocol = tcp)(host = 127.0.0.1)(port = 1521))

5. 關閉後再啟動

listener

執行->cmd

啟動dos

視窗，執行

lsnrctl stop

關閉，lsnrctl start
