配置oracle服务器以从外部机器访问oracle

    今天在虚拟机里面装了个Oracle，之后发现不能从主机访问,觉得是监听程序配错了，开始修改listener.ora(路径是：c:\app\xp\product\11.2.0\dbhome_1\NETWORK\ADMIN)，把监听的主机由  localhost 改成虚拟机的IP。

     如下： 

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (DESCRIPTION =
#原来的是(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) ，也就是把localhost改成你自己机器的ip
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.24.128)(PORT = 1521))
    )
  )

这里再用:sqlplus /@orcl as sysdba 连接，oracle会报：ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务,通过在这个文件里面加条配置就可以解决：

 

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\xp\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\xp\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
#这是新加上去的
    (SID_DESC =
      (GLOBAL_DBANAME = orcl)
      (SID_NAME = orcl)
      (ORACLE_HOME = C:\app\xp\product\11.2.0\dbhome_1)
    )
  )
