4、执行诊断过程
执行start参数，进行诊断。
[Oracle@SimpleLinux prw]$ ./prw.sh start
Wed Apr 30 09:32:21 CST 2014: Starting Procwatcher
Wed Apr 30 09:32:21 CST 2014: Thank you for using Procwatcher. :-)
Wed Apr 30 09:32:21 CST 2014: Please add a comment to Oracle Support Note 459694.1
Wed Apr 30 09:32:21 CST 2014: if you have any comments, suggestions, or issues with this tool.
Procwatcher files will be written to: /prw
Wed Apr 30 09:32:21 CST 2014: Started Procwatcher
对应目录/prw中，就有诊断的结果显示。

目录中所有的文件都是对特定实例后台进程的分析和dump结果。Procwather是一个综合性程序，如果存在ASM实例，或者诊断RAC环境，对每一个实例都会有专门的文件夹。
结果进程中包括三个类型结果：首先是核心后台进程解析，比如dbwr、pmon等关键进行的dump结果和跟踪结果。第二部分是特定后台Server Process分析。如果Procwather的确发现相互锁定的进程，会特意将这些进程信息导出。最后就是分析情况，会从latch、sessionwait、lock和SQL Timing等多个角度进行分析。从快速问题分析的角度看，最后一部分是比较重要的。
目录PRW_SYS_SIMPLELINUX中包括的就是分析过程中使用的脚本和中间结果文件。
