RDA(RemoteDiagnostic Agent)是Oracle用来收集、分析数据库的工具，运行该工具不会改变系统的任何参数，RDA收集的相关数据非常全面，可以简化我们日常监控、分析数据库的工作。
一般Oracle 原厂的人巡检也是使用RDA工具。 不过一般国内的DBA 巡检时很少使用这个工具，一般都是通过AWR 或者自己整几个脚本，跑了在分析一下就ok了。
在MOS 上创建SR(Service Request)时（我08年刚接触Oracle时，那是MOS 上还是称呼Tar，后来改成了SR了）。 Oracle 也会要求客户上传RDA的信息。 通过RDA 可以快速的了解系统的状况。
RDA 是用Perl 脚本写出来的。 可以通过MOS 下载RDA。 RDA 是一个客户端，解压缩之后就可以直接使用了。

RDA 4 Release Notes [ID 414970.1]
RemoteDiagnostic Agent (RDA) is a command-line diagnostic tool that is executed by anengine written in the Perl programming language. RDA provides a unified packageof support diagnostics tools and preventive solutions. The data capturedprovides Oracle Support with a comprehensive picture of the customer'senvironment which aids in problem diagnosis.
Oracle Supportencourages the use of RDA because it greatly reduces service request resolutiontime by minimizing the number of requests from Oracle Support for moreinformation. RDA is designed to be as unobtrusive as possible; it does notmodify systems in any way. It collects useful data for Oracle Support only anda securityfilter is provided if required.
At this time,RDA has been successfully tested to run on the following Supported platforms:
1) Apple Mac OS X/Darwin
2) HP OpenVMS Alpha 7.3-2 andabove
3) HP OpenVMS Itanium
4) HP Tru64 UNIX

You can run RDAalso on other platforms that support Perl 5.005 and later. However, OracleSupport recommends testing on a non-production server first because theperformance is unpredictable. For example, you will receive errors when RDAattempts to run utilities and commands that are not supported on theseplatforms.
