【工具】一款oracle rac 检查工具

一 raccheck 是什么 RACcheck is a RAC Configuration Audit tool  designed to audit various important configuration settings within a Real Application Clusters (RAC), Oracle Clusterware (CRS), Automatic Storage Management (ASM) and Grid Infrastructure environment. raccheck 可以审计如下组件的配置信息：   1 OS kernel parameters
  2 OS packages
  3 Many other OS configuration settings important to RAC.
  4 CRS/Grid Infrastructure
  5 RDBMS
  6 ASM
  7 Database parameters
  8 Many other database configuration settings important to RAC
  9 11.2.0.3 Upgrade Readiness assessment 二 支持的版本
  3 rules.dat 其中collections.dat  rules.dat 称为raccheck的驱动。注意：一个raccheck工具的驱动不能手工更改！ 四  何时使用    1 第一次安装完成rac     2 在例行的os维护之前    3 在例行的os维护之后     4 至少三个月一次 五 提供那些参数： 仅仅在数据库服务器上以oracle用户安装和运行该软件即可，如果没有则需要在root 用户下了！
raccheck 有以下几个参数：     1.  -a - performs all checks, best practice and Database/Clusterware patch/OS recommendations. 
    2.  -b - best practice recommendations only 
    3.  -p - database/clusterware patch recommendations only 
    4.  -f - offline, performs analysis for all 
    5.  -u - performs pre-upgrade and post-upgrade readiness checks (see Appendix M for a full 
        description of the upgrade readiness feature) 
             a. supports upgrade readiness checks for upgrading to 11.2.0.3 or higher 
            b.  Pre-upgrade (11.2.0.3) checks require the additional argument pre (specified by -o): 
                 $ ./raccheck -u -o pre 

             c. Post-upgrade (11.2.0.3) checks require the additional argument post (specified by -o): 
                 $ ./raccheck -u -o post 

    6.  -S - please see the  How to Run RACcheck Silently section for more on this argument 
    7.  -s - please see the How to Run RACcheck Silently section for more on this argument 
    8.  -c - for use when checking individual components, for example: 
                 For only ASM Component Checks: 
                 $ ./raccheck -a -c ASM 

                 For only ACFS Component Checks: 
                 $ ./raccheck -a -c ACFS 
    9.  -o - for invoking various optional functionality: 
                v or verbose would display PASSing audit checks as well as non- 
                 PASSing: 
                 $ ./raccheck -a -o v 
                 $ ./raccheck -a -o verbose 
                 $ ./raccheck -a -c ASM -o verbose 

    10. -v - returns the version of the tool 
    11. -m - supresses the Maximum Availability Architecture Scorecard which is now enabled by  default in RACcheck ！  六 如何使用RACcheck    1 以oracle 用户(如果没有安装oracle rdbms ，则以root 用户执行)   2 在将要执行racckeck 工具的节点的本地目录上 accheck --   3 unzip raccheck.zip 工具 将脚本和驱动文件放到同一个目录下。   4 验证此工具是否具有+x 权限，如果没有则：     chmod +x raccheck   5 执行如下命令：     ./raccheck -a  将会出现如下样式的输出： oracle@rac1:/home/oracle/software ./raccheck  -a

96 of the included audit checks require root privileged data collection . If sudo is not configured or the root password is not available, audit checks which  require root privileged data collection can be skipped.
1. Enter 1 if you will enter root password for each  host when prompted
2. Enter 2 if you have sudo configured for oracle user to execute root_raccheck.sh script 
3. Enter 3 to skip the root privileged collections 
4. Enter 4 to exit and work with the SA to configure sudo  or to arrange for root access and run the tool later.
Please indicate your selection from one of the above options[1-4][1]:- 1

如果选择了1 则下下面的提示中会让用户输入root的密码：如果没有在规定时间内提供密码，以root权限进行的收集工作会被kill掉并继续进行！如下所示 如果及时提供了root用户的密码，则结果如下图： 6 当整个raccheck 工具检查完成之后会生成如下文件：zip 文件和 执行raccheck过程的目录存放临时文件 还有 html文件  用户可以把生产的文体交给sr 以便进行分析~！
