identify high workload from awr report

Hi All,

Yesterday, our well-tuned the batch ran very slowly. Most of jobs ran for 30 mins that usually cost 15-20mins. And the colletion of statistics took much longer than before.

After reading the awr report, I noticed that all top SQLs didn't belong to our batch. Most of them are MV refreshing and bitmap index building.

So I think it is this unexpected high workload who is the culprit of the bad performance. But I want to know which section of awr report can show this or let management accept it?

Best regards,

Leon
