Top 10 postings in 2012

The following postings got most of your views here in 2012:

1. adrci: A survival guide for the DBA

Many DBAs used this article to get a quick start with the new Automatic Diagnostic Repository feature in 11g. Although it is pretty much everything also documented, it requires quite an effort to dig through it there.

2. Brief introduction into Materialized Views

Still one of my most popular writings, this article seems to be regarded by you as a good way to learn about the purpose & concepts of Materialized Views. The many examples make it (I hope) easy to understand and to adopt.

3. Voting Disk and OCR in 11gR2: Some changes

We have seen significant changes for the clusterware & ASM in 11gR2 and this popular article tries to introduce & explain the (in my opinion) most important ones.

4. Exadata

This is a collection of my postings about Exadata – a topic that gains more and more momentum not only here on my humble little Blog 🙂

5. Turning Flashback Database on & off with Instance in Status OPEN

The headline tells almost the whole story here – but a surprising amount of DBAs missed that as an 11g New Feature

6. How do NOLOGGING operations affect RECOVERY?

A very important and popular topic. The article highlights the advantages and especially the drawbacks of NOLOGGING as well as how to recognize that there is a need of action for the DBA.

7. 11gR2 RAC Architecture Picture

To my surprise, this graphic was getting popular very fast, which motivated me to create some more of those pictures in subsequent postings as well.

8. Reorganizing Tables in Oracle – is it worth the effort?

Oracle Forums are getting questions about this topic every day. Short answer: Probably not. Click on the link above for the long answer 🙂

9. Exadata Part III: Compression

Hybrid Columnar Compression came up together with Exadata. The article gives an introduction into it and also briefly explains the difference to Block Compression methods.

10. Data Guard & Oracle Restart in 11gR2

Data Guard is one of my favorite topics and the writing explains its relation to the new Grid Infrastructure for a Standalone Server aka Oracle Restart.

These 10 postings alone got about 70,000 hits of in total about 200,000 hits on my Blog in 2012. Thank you very much for visiting and a Happy New Year 2013 to all of you!
