oracle遇到性能问题时，性能分析的一个思路就是导出AWR分析报告，通过报告分析定位问题根源，以下是oracle10g如何生成分析报告的步骤，oracle10g AWR分析报告文件类型分为txt和html两种，本人习惯使用html。
[root@linux5 /]# su - oracle

[oracle@linux5 ~]$ export ORACLE_SID=orcl

[oracle@linux5 ~]$ cd $ORACLE_HOME/rdbms/admin

[oracle@linux5 admin]$ sqlplus /nolog

SQL> conn /as sysdba
Connected.

SQL> @awrrpt.sql
