来自官方文档：（1）Can I change the public hostname in my Oracle Database 10g Cluster using Oracle Clusterware? Hostname changes are not supported in Oracle Clusterware (CRS), unless you want to perform a deletenode followed by a new addnode operation. The hostname is used to store among other things the flag files and Oracle Clusterware stack will not start if hostname is changed. （2）Does the hostname have to match the public name or can it be anything else? When there is no vendor clusterware, only Oracle Clusterware, then the public node name must match the host name. When vendor clusterware is

一、ModSecurity的规则 基本格式 SecRule VARIABLES OPERATOR ACTIONS 1 SecRule：ModSecurity主要的指令，用于创建安全规则。 VARIABLES ：代表HTTP包中的标识项，规定了安全规则针对的对象。常见的变量包括：ARGS（所有请求参数）、FILES（所有文件名称）等。 OPERATOR：代表操作符，一般用来定义安全规则的匹配条件。常见的操作符包括：@rx(正则表达式）、@streq(字符串相同）、@ipmatch(IP相同）等。 ACTIONS：代表响应动作，一般用来定义数据包被规则命中后的响应动作。常见的动作包括：deny（数据包被拒绝）、pass(允许数据包通过）、id（定义规则的编号）、severity(定义事件严重程度）等。 二、ModeSecurity规则例解 规则1：防XSS攻击 SecRule ARGS|REQUEST_HEADERS "@rx <script>" "id:001,msg: 'XSS Attack',severity:ERROR,deny,status:404" VARIABLES ARGS：所有请求参数； REQUEST_HEADERS：请求数据头部。 OPERATOR @rx <script>：如果正则匹配字符串"<script>"成功，则规则执行。 ACTIONS id
