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.
In February ’17 I participated in Mike Dietrich’s upgrade workshop and it was great! I don’t want to repeat stuff that he said there, you can read everything on his blog. This workshop made me think about upgrades I did in the past (and I did quite a few) and important things to think about before and after upgrading a database.
One of my customers is working with ASM and their database grows really fast. So every one in a while we need to add another ASM disk to the system.
Remember my post about Oracle 12.2 release date? I’ve heard rumors that Oracle changed the date to March 1st, and it was right!
Oracle 12.2 is available for download for Linux x86-64, and Solaris (both SPARC and x86-64). I don’t know the release dates for other platforms. This is the download page: http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
I’m downloading it as I write, and hopefully will have time to play with it a little bit soon. I wrote so much about new features that I have to try some of them at least. Stay tuned!
A few days ago I was browsing the documentation and suddenly realized that I haven’t gone over the 12.2 books. One of the things I like to do is reading the “New Features” guide, so I did. After writing about the major features, here are some smaller ones, but still important enough to know.
