如何生成Oracle AWR报告

如何生成Oracle AWR报告 （awrrpt）

2008-12-19 11:17

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$ORACLE_HOME/rdbms/admin目录，在sqlplus下运行@awrrpt脚本，按照提示一步一步就可以达成，导出的格式有两种，txt格式和html格式。 在OTN上，有一个DBA新feature系列，第六周就是专门讲的这个feature，大家可以去那里了解一下（中文的） Script started on Sun 27 Jan 2008 08:47:15 PM PST [ractest@sun880-1 /u01/app/oracle/orahome/rdbms/admin]$ cd $ORACLE_HOME/rdbms/admin [ractest@sun880-1 /u01/app/oracle/orahome/rdbms/admin]$ sqlplus / as sysdba SQL*Plus: Release 10.2.0.4.0 - Production on Sun Jan 27 20:47:38 2008 Copyright (c) 1982, 2007, Oracle.
