ORAchk 之前被称为RACcheck，后来它的检查范围进行了扩展，改名为了ORAchk，它是在数据库系统进行健康检查的一个专用工具，
这个工具主要用来检查软件的配置是否符合要求以及一些最佳实践是否被应用了。
通过这个工具，用户可以很方便地、自动化地对自己的系统进行健康检查和评估。
ORAchk 能够检查的软件主要有：OS、Oracle Clusterware (CRS)、 Grid Infrastructure environment(GI)、Automatic Storage Management (ASM)以及Real Application Clusters (RAC)、单机的数据库、Golden Gate。
检查的项目包括：- OS kernel 参数
- OS 包/补丁
- OS上其它和RAC相关的配置
- CRS/Grid Infrastructure
- RDBMS
- ASM
- 数据库参数
- 对于RAC数据库影响较大的设置
- 升级到11.2.0.3/11.2.0.4/12c时的升级检查
-
Maximum Availability Architecture (MAA)检查
目前支持的平台：
o Linux x86-64* (Enterprise Linux, RedHat and SuSE 9, SuSE 10 & SuSE 11)
o Oracle Solaris SPARC (64-bit)(Solaris 10 and 11)
o Oracle Solaris x86-64 (Solaris 10 and 11)
o IBM AIX on POWER Systems (64-bit) **
o HP-UX PA-RISC (64-bit)**
o HP-UX Itanium **
- 不支持32位平台，不支持 Linux Itanium
- 需要安装BASH Shell 3.2 或之上
目前支持的数据库版本:
- 10gR2
- 11gR1
- 11gR2
- 12cR1

64 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.
- Enter 1 if you will enter root password for each host when prompted
- Enter 2 if you have sudo configured for oracle user to execute root_orachk.sh script
- Enter 3 to skip the root privileged collections
- 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 for root access[1-4][1]:- 1
Is root password same on all nodes?[y/n][y]y
