Officially I didn't hold a full time job as DBA in any of my previous employments, however this doesn't stop me from getting one or two DBA certifications, because my hunger for knowledge and piss off with some moments where intricacy of DB technical details hinder my architecting and design process.
Besides all the formal knowledge and information I acquainted, one of the most important experience is to further understand the scope, responsibility and difficulties that real DBA faced in their daily operational routines and when application development needs conflicted with the interest of maintaining corporate data policy and security auditing.
In the enterprise application paradigm, the only way a solution architect can architect a better solution is to completely understood and blend every piece of the jigsaw puzzle together into a coherent whole, in the right way.
That's my motivation. Now let me share my preparation process.
1.) Read up the IBM DB2 701 Preparation Materials from IBM
Nothing much to say here.
2.) Read up DB2® Universal Database™ v8 for Linux®, UNIX®, and Windows® Database Administration Certification Guide, by George Baklarz, Bill Wong
You can opt to skip the last part regarding Application Development, even though no harm for you to take a look into it. That part is more relevant when you were taking exam 703.
3.) Do at least one project dealing with DB2 DBMS
4.) Do your own exploration and experiments with some of the concepts in the materials like HADR, Roll Forward and etc.
5.) Get enough coffee and sleeps. Trade off between these 2 important constraints :-)
Lastly, I'd like you to know that DB2 V9 series of examination is already available and you should jump on the bandwagon of V9 if your company or projects are using it or potentially will. I sticked to V8 because that's the one bundled together with IBM DBW DWE V9.1 and I dealt with that version of DB2 the most.
P/S: I got a 100% score in this exam. Cheers. I finally revenged on my 98% score in exam 700. :EVIL:
