In the previous part I explained the top part of the report. In this part I’ll continue with the actual information about database activity, what we are looking for and other important things we can find in 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.
