如何生成Oracle AWR报告
Oracle性能分析入门学习中,遇到Oracle数据库的性能问题,一般首要的步骤就是导出AWR的分析报告,AWR是10g中新引入的一个工具,在这之前一般是利用statspack。要导出AWR报告,只要利用Oracle的一个脚本即可以完成,下面是我利用script录制的一段导出AWR report的过程。
首先进入$ORACLE_HOME/rdbms/admin目录,在sqlplus下运行@awrrpt脚本,按照提示一步一步就可以达成,导出的格式有两种,txt格式和html格式。

在OTN上,有一个DBA新feature系列,第六周就是专门讲的这个feature,大家可以去那里了解一下(中文的)
