易如反掌不用杀毒软件也能消灭病毒

作者：宋政编辑：杨晓勇 2007-07-17 07:35

    【IT168 专稿】本文是Redhat下Oracle9i 安装全攻略系列的第三篇《脚本精选》。其他参见《中文显示》、《安装指南》、《常见错误》。

    脚本说明：对 grep 程序路径和参数进行管理，是为了确保在SunOS/HP-UX及Redhat 9.0/Redhat AS3运行的兼容性，得到准确的检查结果。如果不作特别声明，以下内容默认是以 root 权限操作的。

    /etc/rc.d/init.d/dbora 这个脚本是以 Oracle 8i 和 Redhat 7.3 为基础设计的，修改个别参数后能在 Oracle 9i 和 Redhat 9.0、Redhat AS3上正常使用。因为篇幅的关系，请大家参考网页。

    Oracle 的标准系统服务脚本 for Redhat Linux

    $ORACLE_HOME 的 .bash_profile 和 .bashrc 这两个是 oracle 登录脚本
    /usr/bin/dbstat 通过 ps, lsof, grep 这几个命令,来检测服务运行状态

    /usr/bin/mc 修改 gcc 和 gc++ 的当前版本,一般是 link 到 296 或 323
    /usr/bin/mn 过滤 chinput 垃圾信息要用,必须确保 /dev/null 设备存在
    /usr/bin/mo 如果 Oracle9i 已经安装，但是 dbstart 不能用，这里修正

    /usr/bin/pc 运行 chinput，常用在 Linux 本机 X，WinXp 的 Xman，Vnc
    /usr/bin/pg 查找名字包含特定字符的进程，显示出来。例如 pg chinput
    /usr/bin/pk 查找名字包含特定字符的进程，并且杀掉。例如 pk chinput
