proactive Vs reactive tuning

Posted by Pavan DBA on August 23, 2010


Long back i posted a poll asking my friends, which type of tuning they will prefer…and to my expectation, almost 90% said Proactive tuning…

I doubt (or atleast not sure) if working DBA’s who polled for “proactive tuning” really follow the same in their work because Tuning is one area which DBA’s are afraid off (but ofcourse some people enjoy it 🙂 )

The answer for the poll is reactive tuning on major, but yes sometimes we do proactive tuning

Now, each kind of tuning is having its own advantages and disadvantages. In proactive tuning DBA need to concentrate or predict on future database problems which is very tough where as in reactive tuning, DBA should have good troubleshooting skills and should be a fast decision taker as sometimes PT problems dependent on client business.

So friends, conclusion is….DON’T TRY TO CHANGE WHICH IS ALREADY WORKING FINE by doing proactive tuning and DON’T BE SLOW when doing reactive tuning.

More articles are in pipeline on tuning methodologies….continue to watch this space….

Votes went wrong & role of DBA in future

Posted by Pavan DBA on June 11, 2010


Hi Friends,

Long back i posted a voting query in my blog and thanks a ton for the response you had given.
But, unfortunately, max votes are posted for incorrect answer.

Let me present the same question with options here…

Which of the following DBA should have?
1) Responsibility of task
2) supporting application team while handling issues
3) provide solutions in cost effective way

I got Max votes for option 2 and to be frank, all are the answers for the question. But i posted this query to you to know out of these 3 which you feel the most important.

In my view, option 3 is the perfect answer…not accepting 😦 … oh! let me give you description.

We know in every version Oracle is brining automized features in database administraion. Many DBA’s asked me a simple question “what is the role of DBA in future if everything is automated?” or “whether DBA’s will have work or job to do if all are automated?

Now my only answer to this is….We need to grow from being a regular DBA to DBA who can be a Data Architect. Apart from this, there are many roles to play right from apps to fusion middleware.

The below two links from the great Don Burleson and Tom Kyte will explain in detail…

Hope this cleared some of your queries and if you still have, please post them through commenting… eagerly waiting to reply them 🙂

Now that’s apt………..just read these 5 liners :-)……………………………

Posted by Pavan DBA on March 5, 2010


1. Once, all villagers decided to pray for rain. On the day of prayer all the People gathered, but only one boy came with an umbrella…  

THAT’S FAITH.

2. When you throw a baby in the air, she laughs because she knows you will  catch her…

THAT’S TRUST.

3.Every night we go to bed, without any assurance  of being alive the next Morning. But still we set the alarm to wake us up…

THAT’S HOPE.

4. We plan big things for tomorrow in spite of  zero knowledge of the future, or having any  certainty of uncertainties. ..

THAT’S CONFIDENCE.

5. We see the world suffering. We know there is a possibility of same or similar things  happening to us. But still we get married!!!!!!……………….
 
THAT’S OVER CONFIDENCE
