After talking a bit about the AWR report (if you haven’t read the previous posts, you can find part 1 here and part 2 here), I think one of the best ways to understand it is to talk about real examples. In this part I’ll give you a few examples and tips regarding the report.
Once in a while I get requests for some information about reading and analyzing an AWR report. I have been thinking for a long time about writing such a post, but always postponed it as it is a very tricky topic. The AWR (or statspack for that matter) report is huge and contains so much information that it’s easy to get lost. It also requires a lot of knowledge about the database and the different mechanisms so it’s very difficult to explain all of this in a blog post (or even a series of posts). In this post I’ll try to start from the beginning, explaining a little bit about the AWR report and the analysis process and we’ll see where it takes us.
