操作系统：windows7X64

安装软件：oracle 11g

开始->程序->Net Manager

查看本地IP

修改主机为IP地址（否则局域网其他电脑不能访问）

打开services.msc启动监听服务

增加配置tnsnames.ora文件

TEST =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST =172.27.35.8)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )

常见错误：ORA-12514: TNS:listener does not currently know of service requested in connect

解决方案：

修改listener.ora文件为

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
      (SID_NAME = ORCL)
	)
    (SID_DESC =
      (PROGRAM = extproc)
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.27.35.8)(PORT = 1521))
    )
  )

至此，同一局域网的其他电脑就可以访问本地oracle服务器了
