Awr报告生成方法
进入$ORACLE_HOME/rdbms/admin目录,在sqlplus下运行@$ORACLE_HOME/rdbms/admin/awrrpt.sql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,用html格式的比较好看一点
具体操作方法如下:
bash-3.00$ echo $ORACLE_HOME
/export/home/oracle/product/10.2.0
bash-3.00$ cd /export/home/oracle/product/10.2.0/rdbms/admin/
bash-3.00$ sqlplus / as sysdba
