配置文件路径：\NETWORK\ADMIN

如：C:\Oracle11gR2\product\11.2.0\dbhome_1\NETWORK\ADMIN

一、修改配置文件：listener.ora

# listener.ora Network Configuration File: D:\Oracle11gR2\product\11.2.0\dbhome_1\network\admin\listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = CLRExtProc)

(ORACLE_HOME = D:\Oracle11gR2\product\11.2.0\dbhome_1)

(PROGRAM = extproc)

(ENVS = "EXTPROC_DLLS=ONLY:D:\Oracle11gR2\product\11.2.0\dbhome_1\bin\oraclr11.dll")

)(SID_DESC=(SID_NAME=orcl)

(ORACLE_HOME = D:\Oracle11gR2\product\11.2.0\dbhome_1)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))

)

)

ADR_BASE_LISTENER = D:\Oracle11gR2

修改listener.ora配置文件中LISTENER节点中host的地址由localhost为IP地址。

另外，一定要在SID_LIST节点中添加一个SID_DESC节点说明。否则会在启动服务时会报如下错误提示。

二、修改配置文件：tnsnames.ora

修改tnsnames.ora配置文件中的地址为IP地址：

# tnsnames.ora Network Configuration File: D:\Oracle11gR2\product\11.2.0\dbhome_1\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.

LISTENER_ORCL =

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

ORACLR_CONNECTION_DATA =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

(CONNECT_DATA =

(SID = CLRExtProc)

(PRESENTATION = RO)

)

)

ORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

通过以上的配置后，重启Oracle监听及实例服务后即可在其他计算机中通过IP地址连接。
