Today (1st March 2017) I will finally start my Oracle OCM 12c study project. Almost 2 years after start studying for the OCM 11g and 1 year from becoming an OCM 11g, I have another big adventure and challenge in my life!
My target is to take the exam by August/2017.
UPDATE 1: I did it on August 14th in Reading, UK. Now I’m waiting for the results! (More information in sections 6 and 7).
P.S: I made a separate post about my OCM 12c Trip that can be accessed here.
UPDATE 2: After 29 very long days (almost like OCM 11g), the result finally came on September 12th and now I’m officially and OCM 12c! (More information in section 8).
As I did with the OCM 11g, 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.
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.
Note that here are listed the topics for the OCM 12c FULL exam (2 days) and UPGRADE exam (1 day). If you plan to take the OCM 12c FULL exam (2 days), for the non-listed topics I recommend you to take a look in my OCM 11g Preparation page as some of them are very similar (and do not forget to check the new features for each).
Let's start:
1 - Before you begin
- Recommended Hardware for Study
- Download the Exam Environment
- Prepare your Environment
- Course Requirements / OCM 12c Exam Preparation Workshop
- Where to take the exam
2 - Scoring
For the first time in an OCM exam, Oracle defined the minimum scoring to pass in each skillset.
*Acceptable performance on each skillset:
For UPGRADE exam:
- Skillset 1 - 56%
- Skillset 2 - 32%
- Skillset 3 - 43%
- Skillset 4 - 44%
For FULL exam:
- Skillset 1 - 60%
- Skillset 2 - 46%
- Skillset 3 - 40%
- Skillset 4 - 33%
- Skillset 5 - 39%
- Skillset 6 - 42%
- Skillset 7 - 54%
- Skillset 8 - 36%
UPDATE: This information is not available anymore in Oracle website, so the minimum may have changed.
This only show us how hard is the OCM exam. You must score less than 60% to be approved! Skillset 2 only requires you to score one third of the questions. So "expect the best, plan for the worst, and prepare to be surprised."
I believe that each skillset is respectively associated with the topics as that are listed (in the same order).
If you do not pass, they give also some information:
- Candidates must wait 14 days before retaking a failed proctored exam. (Registration will be allowed on the 14th day)
- Candidates are only allowed 4 attempts to pass an exam in a 12-month period.
- Candidates must resubmit a failed Master Assignment within 30 days of receiving the notification of failing.
This basically means that you should wait almost 2 months if you consider that you are not allowed to retake a passed exam and the exam results takes 4-5 weeks to arrive.

5 - Others Certifications as study strategy
As I did when studying for OCM 11g, in the OCM 12c there are a lot of Oracle Certifications that you can take as a way to study for 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 Certified Expert, Oracle Database 12c: Data Guard Administrator
- Data Guard
- Oracle Certified Expert, Oracle Database 12c: Performance Management and Tuning
- Data and Performance Management
- Oracle Certified Expert, Oracle Database 12c: RAC and Grid Infrastructure Administrator
- Grid Infrastructure and Real Application Clusters
- Oracle Database 12c Administrator Certified Professional(upgrade)
- General Database and Network Administration, and Backup Strategy
The best of taking all that combo above is that you will also become an Oracle Database 12c Maximum Availability Certified Master.
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.
6 - 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.
I made a separate post about my OCM 12c Trip that can be accessed here.
7 - 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 September/2017. =]
8 - The Results
After 29 long days waiting, months of dedication and more than 10 years working with Oracle DB, I could not be happier with the result. Now, I'm officially an OCM 12c.
The OCP team sent the result at 9h44 UTC-3.
As they are not shopping kits to Brazil as the government is taxing any type of incoming (even presents), I've asked to receive the OCM kit by mail in a US address.
9 - External Pages that Helped!
Alex Zaballa posted a series of topics while he was studying for his OCM 12c Upgrade Exam in OTN Brazil page. Those topics help and serve as a guide also for the Sections 1 and 2 of the Upgrade Exam. However they are all written in Portuguese language, so if you don't understand the language use a webpage translation tool.

Hi
First , thanks a lot for the information in your blog.
I'am from Sengal e and I'am currently OCP and /OCE 11g RAC.
How many times do you thonk it can take for me the OCM exal preparation ?
Autor
Hi Cheikh,
Well, it depends a lot of your practical experience on the exam topics. If you have knowledge on them but not the daily expertise, you would require at least 1-2 years. Otherwise 6 months is fine.
Thanks,
RJ
Hello Rodrigo,
what is your daily routine for learning? Considering 1-2 hours per day during the week and 4-5 hours during the weekend, roughly...with 5~6 years of experience, do you think 6 months is enough for preparation. I can`t say that I know everything, but try to be up to date (webinars,seminars, blog posts etc.).
Regards, Petar

You need to cover all the topics at least twice and doing the things in all possible ways.
It's hard to tell based on years with experience as it depends more on the diversity of the environment and your tasks, I think that you would need at least 1 years studying 3-4 hours/day.
Thanks,
RJ
please share the best way to browse the 12c oracle documentation. It's harder to browse than the 11g version.
Thanks
Autor
I recommend the same one that comes with in Oracle Linux 6.5, which means firefox-17.0.10-1.0.1.
Good luck,
RJ
Hi,
Thanks for your valuable info and tips.
Are all modules in the exam of equal duration?
Will the exam duration for each modules vary?
I have set my OCM exam next week.
Cheers,
Deepak

Hi Deepak,
Unfortunately, I cannot tell you anything about the exam itself due to signed NDA.
Good luck!
Rodrigo Jorge
Hello Rodrigo, thanks for the blog..
During the exam, could you use Cloud Control to build the Dataguard environment? because i know that is faster than by hand for the exam.
Thanks
Autor
Hi Carlos,
Unfortunately, I cannot tell you anything about the exam itself due to signed NDA. You should practice and be well prepared all the possible ways imagined to do something, in case the exam constraints the ways you can do something (GUI or CLI). Then use your best approach available.
Thanks,
RJ
Congrats again Rodrigo! Someone who is thinking about taking 12cOCM upgrade next may in UK?
Hi Rodrigo,
Thank you so much for the useful information. I am an Oracle 11g OCP and looking to become 12c OCM. I know I will have to first upgrade my 11g to 12c OCP.
My quick question to you is, which two advanced training courses would you recommend? Recall two trainings are a mandatory prerequisite to becoming an OCM. I have seen folks who did their OCM recommend RAC administration and performance training. I understand you upgraded from 11g OCM to 12c OCM so you might not have had to take the trainings again but you must have taken 2 trainings when working on your 11g OCM, so do you think that helped? Do you have any training in particular that you recommend people like me that may help with OCM exam?
Truly appreciate your response.
Thanks,
Autor
Hey Shab, how are you. Got your point, did you see this sub-article from my OCM 12c Prep page https://www.dbarj.com.br/en/2017/05/ocm-12c-preparation-course-requirements/?
So the OCM 12c Preparation Workshop is a very good course that I advise. As a second one, I would recommend someone related with the skillset you face more difficulties during this first workshop =].
I just passed my OCP 12c exam. What is path to upgrade to 12c OCM?
My Question Detailed,
Hi, I am an Oracle Certified Professional DBA in 9i. And i want to upgrade my Oracle 9i OCP to Oracle 12c DBA Exam. So, Kindly let me know which exam should i give to upgrade my certification from Oracle 9i OCP DBA to Oracle 12c DBA.
Please Reply Us.

Hi Asif, you need to take the 1Z0-060 exam to become 12c OCP. After that you can do the OCM 12c Exam.
I took the exam yesterday.
I am waiting the result.
I just successfully passing the Oracle Database 12c Certified Master Upgrade Practicum.
Its really helpful information.Thank you
Hi,
Thanks for putting up everything together. I checked the exam schedule for 12c oCM exam and there is none in US. There are only 4 schedules available with 3 in CN and 1 in UK.
Is Oracle going to release a new schedule for the second half of 2020?
Thanks for the info. Do you have any information about newer Oracle OCM certification for 19c version
Autor
Hi Kapil,
The last information I had from the Certification Team is that there is still no plan to have a 19c OCM exam.
Regards,
RJ
