Today (22nd October 2014) I will start my Oracle OCM 11g study project. I will list here the topics and some study guides for each of them, so I can exchange with you who is also applying, interested or have any skills. Please comment in the post related to each topic if you find out any more valuable information to add.
My target is to take the exam by October/2015.
UPDATE 1: I did it on 14th AND 15th October IN Bucharest, Romania. Now I’m waiting for the results! (More information in section 4 and 5).
UPDATE 2: After 35 long days, the result finally came on 20th November and now I’m officially and OCM! (More information in section 6).
Every topic will have a link to a post where I will cover some test cases, what is needed to study and the link to the official Oracle Doc related. Remember, the Oracle Official Doc is all you will have on the day of the exam, so being fast and getting to the item in the DOC is a necessity.
1 – Before you begin
2 – Topics
Those topics were get from the official Oracle OCM website on Oct/2014. I will update if I notice any modification.
I recommend you to print this list in a front/back page (you can get the pdf here and print it) and “check” each completed item with a pen! It’s a good way to control your progression. Thanks to Kamran for this tip.

3 – Others Certifications as study strategy
One very good path to study for the OCM is taking other Oracle Certifications as a way to cover a topic. This is the way I’m doing and I recommend it. The work & study required to prepare for certification exams broadens your knowledge by exposing you to a wide variety of essential functions, features & tasks.
Getting certified also adds a lot of benefits for you and your career, as Oracle listed here.
So, what extra certifications do I recommend you to take as you study and for what topics do they prepare you?
- Oracle Database 11g Data Warehousing Certified Implementation Specialist
- Data Management
- Data Warehouse Management
- Oracle Database 11g Performance Tuning Certified Expert
- Performance Management
- Oracle Certified Expert, Oracle Real Application Clusters 11g and Grid Infrastructure Administrator
- Grid Infrastructure and ASM
- Real Application Clusters
- Oracle Enterprise Manager 11g Certified Implementation Specialist
- Enterprise Manager Grid Control
I hope you don’t ever think in using Brain Dumps for them. Why?
- It’s illegal.
- It will not help you and will not give you any base for any OCM skillset.
- Every Oracle Professional knows that Brain Dumps exists. If some candidate during an interview show me some certification budget, the first thing to do is make some questions that this credential should allow him to answer. Imagine how shameful would be to him not to know basic things.
4 – Tips for the exam trip
Here are some tips that I recommend:
- Arrive some days before the exam to the city to align your biological clock, specially if your time shift is bigger than 3 hours.
- One day before the event, go to the exam place to check if the address is right, where is the room, the best way to arrive, etc.
- Don’t drink any alcoholically things from 3 days before the event. Do it after the second exam day to celebrate (and do it well).
- Don’t eat heavy food or any kind of food that put you stomach at risk during the exam (like fat or sea food).
- Take a good breakfast in the morning. Avoid drinking too much liquid before the exam or during the breaks. Do it after.
- Sleep for at least 8 hours before each exam day. Relax your body and your mind!
- Keep in your pocket some pills for headache that could come.
- Don’t forget to take with you 2 (TWO), I said 2 (TWO) ID’s. Maybe the passport and the other your driver license or your country main ID. If you don’t, you will need to leave. Rules are rules, they will not be flexible with you in this point.
5 – After the event!
After you do the exam, don’t talk any information about anything in the exam to the others (even if it is your best friend or your wife/husband). Why?
- Before starting the exam you must sign a NDA (non disclosure agreement), available here, saying that you won’t say or talk anything about the exam. If you don’t want to sign it, you cannot do the exam and that’s it, good bye. But if you do sign and if you talk to anyone about the exam, you will lose your OCM credential.
- It’s not fair to the ones who studied and worked hard to get it.
- The value of the something is inversely proportional to how easy is to get it. If we have 100K people that are OCM and got it cheating, the ones who didn’t will also be harmed. That’s the case of the OCP certification today, where many people got it using Brain Dumps.
Also, that’s why you usually don’t see much information about the exam in the internet.
And what about the results?
- “Participants will be notified of their final score 4 – 5 weeks following the exam”. So relax during that time also.
- If you pass, celebrate it, you deserve. If you didn’t, don’t give up. Try again! Imagine if the babies give up trying to walk after the first wrong attempt. We would have a world of people crawling around.
I’m still waiting for mine, that will be probably available by November/2015. =]
6 – The Results
After 35 long days waiting, one year of dedication and 10 years working with Oracle DB, I could not be happier with the result. Now, I’m officially an OCM 11g.
The OCP team sent the result at 5h27 UTC/GMT-2.
Soon I will receive the OCM kit by email.
7 – External Pages that helped a lot!
8 – Special Thanks
Alex Zaballa is a Brazilian Oracle OCM and ACE who gave a presentation about “How to became an Oracle Certified Master” in the GUOB Tech Day 2014. This is an OTN event that happens once a year in Brazil.
I’m very thankful to him as this was the kick off for my studies. He also gave a lot of tips that I use in many pages of this article.
He is also known as the 100+ Oracle Certifications man. Here is his webpage link where you can find much more information about him: http://alexzaballa.blogspot.com/
