在阅读AWR报告的时候，TOP 5的等待事件信息的数据肯定是我们必看的数据，但是如果我们只看一个快照的数据其实是没有任何价值的。那最好的方式是什么呢？就是查询出AWR中所有的TOP 5的等待事件数据，根据买一个等待事件的数据趋势来判断是否有异常、什么时候发生的异常等等。
所以今天分享的这个脚本awr_event_top5.sql就是一键获得整个AWR的所有的TOP 5等待事件的信息，并进行格式化，方便阅读。
执行方式
sqlplus '/ as sysdba' <<EOF
@awr_event_top5.sql
exit
EOF结果输入如下
SNAP_TIME EVENT1 AAS1 RATIO1 AVG_TI EVENT2 AAS2 RATIO2 AVG_TI EVENT3 AAS3 RATIO3 AVG_TI EVENT4 AAS4 RATIO4 AVG_TI
