Finally after 3 months of preparation, I have completed the DB 9 Advance DBA certification. It was my 2nd attempt. First time when I gave this exam, I was in an impression that it will be similar to the exams I gave earlier (DBA and Application Development) where I can just read certification guide and will be able to clear it but that was not the case here. When I attempted first time and failed by 4 marks I realized, I do need to read some concepts very much in details. Specifically HA and Performance. HA and performance makes 52% of the exam and you need to have good hold on these topics to get a good score. So I started reading the complete performance and HA guide. While reading I really felt that DB2 is not just SQL and some monitoring stuff. There are a lot in it. It also gave me the feeling how hard it can be to tune a database and how difficult it would be for a DBA to tune a database which is huge in size. This encourage me to read some more administration guide and go for DB2 problem determination certification. And yes that is my next goal for this year. Another certification and a new way to see a database tuning and problem determination.
In case you need some tips and questions, let me know. I will be happy to help who likes DB2 administration.
