Generate AWR Report automatically every day

Question

Hi Friends,
I would like to generate AWR Report automatically every day. How do i do it.
The Start Time will be 00:00 of Previous day and the end Time will be : 00:00 of current day. The File format is html.
Currently i am using awrrpt.sql to generate report manually and i would like to achieve it automatically,I am not sure how to pass the values of start and end time (From which table i can get the values)?
Regards,
DB

Hi, DB.
You may use the below sql script , the sql script generates the AWR report for the duration of 2 days in HTML.
So you  change
1) the where condition as per your requirement,
2) report name in sql script,
3) and convert it as shell or bat script based on your environment, and schedule it in your OS job scheduler / crontab.
