\--==========================  
\-- 配置sqlnet.ora 限制IP访问Oracle  
\--==========================  
  
与防火墙类似的功能，Oracle 提供限制与允许特定的IP或主机名通过Oracle Net来访问数据库。这个功能由sqlnet.ora配置文件来实  
现。该文件通常$ORACLE\_HOME/network/admin/ 目录下，与tnsnames.ora以及listener.ora位于同一路径。用法也比较简单。通过监听器的  
限制，实现轻量级访问限制，比在数据库内部通过触发器进行限制效率要高。  
  
**1. 实现方式**  
通过在sqlnet.ora文件中增加下列记录来实现

> tcp.validnode\_checking = yes tcp.invited\_nodes = (hostname1, hostname2，ip1,ip2) tcp.excluded\_nodes = (10.103.11.17,hostname1,hostname2)

当使用invited\_nodes时，则所有没有包含在invited\_nodes值中的IP或主机将无法通过Oracel Net连接到数据库。而如果使用  
excluded\_nodes时，除了excluded\_nodes值中列出的IP和主机不可访问之外，其余的节点都可以访问数据库。通常情况下，更倾向于使  
用excluded\_nodes参数。  
  
**2. 注意事项**  
使用excluded\_nodes与invited\_nodes的一些特性  
不支持通配符的使用(如hostname不能写为svhs0\*，IP地址不能写为10.103.11.\*）  
excluded\_nodes与invited\_nodes为互斥方式，要么使用前者，要么使用后者  
如果tcp.invited\_nodes与tcp.excluded\_nodes都存在，则tcp.invited\_nodes优先  
要将本地地址，或者Cluster群集其他节点的地址都加入到允许列表，否则监听器可能无法启动  
修改之后，一定要重起监听或reload才能生效，而不需要重新启动数据库  
仅提供对TCP/IP协议的支持  
  
**3. 实战演习**

**4.使用触发器限制单用户或IP段**
