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

1 10gR2

2 11gR1

3 11gR2

三由以下文件组成

1 raccheck

2 collections.dat

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
CRS stack is running and CRS_HOME is not set. Do you want to set CRS_HOME to /opt/rac/11.2.0/grid?[y/n][y]y

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
