Find CPU Intensive Query and Statspack

edited May 2, 2020 3:02PM in Database Administration (MOSC) 8 commentsAnswered

Hello experts,

I am trying to find what exactly is happening at a specific time of my database. The users complain the database is disconnected or very slow between 7:00PM ~ 7:05PM. Since it's such short period time, Statspack doesn't help, I believe (Doesn't it take just point-in-time snapshot of performance data, not period of time?). So the only tool I can use is, v$sql which shows cpu and io stats of each queries. However, I like to collect performance data like what Statspack shows between the 5 minute period of time. How can I do that?

The database is Oracle Database Standard Edition 11g (no diagnostic pack, no awr report licensed)
