oracle提示TNS:无监听程序的解决思路

登录提示：无监听程序的解决思路

看了一下F:\oracle\product\10.2.0\db_2\NETWORK\ADMIN

无下面两个文件

tnsnames

listener

再看了一下服务

CMD->SERVICES.MSC

ORACLE本来应该有三个服务的，少了一个监听服务！

现在从另外一台机器上拷贝过来下面两个文件:

tnsnames

listener

再将里面的内容进行改一下，

现在tnsnames文件下内容为:

COGNOS =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = cognos)

    )

  )

现在listener文件下内容为:

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = F:\oracle\product\10.2.0\db_2)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (SID_NAME = CLRExtProc)

      (ORACLE_HOME = F:\oracle\product\10.2.0\db_2)

      (PROGRAM = extproc)

    )

  )

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

    )

  )

然后再在CMD窗口中输入：lsnrctl start

提示启动成功！

再看看服务窗口，该服务启动了！

用PL/SQL登录进去，一切OK！
