ACE Alumni

Hi all,

As many of you know, I joined Oracle as a Database Product Manager and became an ACE Alumni.

The Oracle ACE Program is intended for Customers and Partners, not for employees.

I was in the program for 10 years and I will continue to support the program, now on the Oracle side.

I'm very thankful for the program, especially for Jennifer Nicholson who runs the program with passion and supported me all these years.

Before I left the program, I had sufficient points for one more year :)



As an Oracle employee, I also need to step out from the Brazil Oracle User Group (GUOB) board, but I will always be helping.



Happy Holidays and see you in 2024!

A Dream Come True: Starting My Journey at Oracle

Dreams have a funny way of coming true when you least expect them. After years of hard work, dedication, and unwavering determination, I find myself at the threshold of a new and exciting chapter in my career: starting at Oracle, the company I've always dreamt of being a part of. Join me on this journey as I share my thoughts, experiences, and the incredible opportunity that has come my way.

Oracle Corporation, a global leader in cloud computing and database technology, has been a beacon of innovation and excellence in the tech industry for decades. From the early days of Larry Ellison's vision to its current status as a tech giant, Oracle has consistently pushed the boundaries of what's possible in the world of technology. For me, Oracle represented not just a company but a place where dreams could become a reality.

Getting to Oracle wasn't a walk in the park. Like many others, I faced my fair share of challenges and setbacks. The tech industry is fiercely competitive, and Oracle's standards are as high as its skyscraper headquarters. I had to put in countless hours of study, gain valuable experience, and network tirelessly to even get my foot in the door. The journey was long, but it was worth every moment.

One sunny morning, while sipping coffee and scrolling through my emails, a message popped up in my inbox that changed my life forever: "Congratulations! You've been selected to join Oracle." The feeling of elation and disbelief that washed over me was indescribable. It was the call I had been waiting for, the culmination of all my hard work and dedication.

Oracle's culture is unique and deeply rooted in its commitment to excellence. The emphasis on teamwork, continuous learning, and pushing the boundaries of technology resonates with me. I found myself surrounded by mentors and colleagues who were not only experts in their fields but also genuinely passionate about what they do.

I will join one of the best and most knowledgeable teams at Oracle, responsible for Oracle Database Upgrades and Migrations. It will take me a while to be at the same level as the rest of the team, but I will work hard on it :)

Starting at Oracle has been nothing short of a dream come true. It's a testament to the power of perseverance, dedication, and God's grace. I look forward to the exciting challenges and opportunities that lie ahead. If you're dreaming of joining your own "company of dreams," remember that with hard work and determination, dreams can indeed become reality.

Stepping Out of Accenture: A Personal Journey Towards New Horizons

After an incredible almost 9 years journey at Accenture, the time has come for me to bid farewell to this remarkable organization and embark on a new adventure. This decision was not made lightly, and it is with mixed emotions that I announce my departure. As I look back on my time here, I am filled with gratitude for the invaluable experiences, lasting relationships, and professional growth that this company has offered me.

My journey at Accenture Enkitec Group began in 2015, and over the years, I have had the privilege of working on diverse projects, collaborating with talented colleagues, and contributing to meaningful technological advancements. From the very beginning, Enkitec's commitment to innovation and excellence has fueled my passion for technology and helped me evolve as a professional.

One of the most rewarding aspects of my time at Enkitec has been the opportunity to work with a team of dedicated and visionary individuals. I am immensely grateful for the mentorship and guidance I received from my colleagues and leaders. Their unwavering support has been instrumental in my personal and professional development.

The decision to leave Accenture was not made lightly, and it is driven by my desire to explore new horizons, tackle fresh challenges, and continue to grow both personally and professionally. I am excited about the possibilities that lie ahead and the chance to leverage the skills and experiences I have gained at Enkitec in new ways.

As I step into this new chapter, I am eager to bring the knowledge, skills, and values I have cultivated during my tenure at Enkitec into new environments, where I hope to make a meaningful impact. I am excited about the opportunities for growth and the chance to explore new avenues in the technology industry.

To my colleagues and friends at Enkitec, please know that this farewell is not a goodbye, but rather a "see you later." I look forward to staying connected and continuing to collaborate in the future.

Thank you, Accenture Enkitec Group, for an incredible 8.5 years of growth, learning, and unforgettable memories. The lessons and experiences I have gained here will always be a part of my professional journey.

As I set forth on this new adventure, I am excited about the opportunities ahead and the chance to make a positive impact in new ways. I am grateful for the memories, the friendships, and the lessons learned during my time at Enkitec. Here's to the future and the exciting challenges it holds!


Sincerely,

Alex Zaballa

How to study for 1Z0-1121-24 - Oracle Cloud Infrastructure 2024 Certified Networking Professional

Hi everyone,

This is a brand-new exam and I decided to try it!
I set for the exam and when I was starting, my internet went down and I had to reschedule for the next day. On the first try, I failed, but I was to pass on the second try :)

This exam is the hardest and most elaborate exam that I have taken in the past few years, so be prepared :)

To start your learning, a good starting point is here:

Don't forget to read the topics:

The practice exam is good and you can have a good feel of what to expect during the exam.

1st attempt: Failed 



After failing and fighting to find the answer for some topics that I was not prepared enough, I contacted 
some friends who passed the exam and asked for some guidance on the documentation to study.

Later, I contacted Sergio Castro from Oracle University and he kindly shared some great links to prepare for the exam:

One of my favorite Oracle Autonomous Database features for developers #JoelKallmanDay

Hi everyone,

One of my favorite features of Oracle Autonomous Database is the possibility to clone and/or move an Autonomous Database.

You can choose to create a full clone, create a metadata clone, or create a refreshable clone.

Clone Types on Autonomous Database:

Full Clone: creates a new database with the source database's data and metadata.

Refreshable Clone: creates a read-only full clone that can be easily refreshed with the data from the source database.

Metadata Clone: creates a new database that includes all of the source database schema metadata, but not the source database data.

You can:

Clone from a database instance: This creates a clone of a running database.

Clone from a backup: This creates a clone when you select a backup from a list of backups, or when you enter a backup point-in-time to clone.

Clone from the latest backup: This creates a clone where the Autonomous Database uses the most recent backup data that is available to create the clone.

And my favorite:

Utilize a refreshable clone as a test database. You have the flexibility to detach a refreshable clone from its source, enabling you to carry out Data Manipulation Language (DML) tasks or perform calculations, in addition to querying data. This grants you the capability to execute DML and implement changes even when the database is disconnected. Once your testing is complete, you can re-establish the connection to the source database, causing the clone to revert to its state at the time of disconnection.

Please note that the option to reconnect is available for a limited period of 24 hours following the disconnection. After this timeframe, the clone becomes permanently separated from the source database, and reconnection becomes unfeasible.

How to study for 1Z0-770 - Oracle APEX Cloud Developer Professional

Hi everyone,

I decided to take all the 2023 OCI exams to check what changed and guide people in taking these certifications.

Well, not all exams. I will do only the ones that I did in 2019 to 2022 and are the things that I work on a day-to-day basis 🙂


I'm not an APEX Developer, but a few weeks ago, I developed an internal tool using APEX and I was very impressed with the tool evolution. The last time that I used APEX to develop something was in 2014 using APEX 4.


This exam consists of 58 questions and you have 1.5 hours to finish.


A good starting point is here:



I hope Oracle is planning to allow us to download the PDFs again because the online reader is terrible. From 0 to 10, the usability of this tool is -1, especially on mobile devices.

Don't forget to read the topics:

https://mylearn.oracle.com/ou/learning-path/become-an-oracle-apex-developer-professional-2023/121230

How to study for 1Z0-1104-23 - Oracle Cloud Infrastructure 2023 Security Professional

Hi everyone,

I decided to take all the 2023 OCI exams to check what changed and guide people in taking these certifications.

Well, not all exams. I will do only the ones that I did in 2019 to 2022 and are the things that I work on a day-to-day basis 🙂


This test has a new format, with hands-on questions. Which is great in my opinion :)

After the hands-on, you will need to answer 25 questions (same as previous exam format).


On this test, I expected to see some new things(comparing the course topics with the previous years). And that's true, I got a lot of new questions.

A good starting point is here:


Reading the Official documentation is always a plus for the exams:


I also recommend you take a deep look at network features, peering, NSGs, SLs, connectivity, and how they relate to security. Don't forget to go deep on Vault, Keys, Secrets, WAF, etc.

I hope Oracle is planning to allow us to download the PDFs again because the online reader is terrible. From 0 to 10, the usability of this tool is -1, especially on mobile devices.

Don't forget to read the topics:

https://education.oracle.com/oracle-cloud-infrastructure-2023-security-professional/pexam_1Z0-1104-23

The practice exam is good and you can have a good feel of what to expect during the exam.

If you are not finding available slots until September/30, just keep trying.
They keep adding slots and this is the answer that I got after opening an SR (Thanks Mónica Godoy for the tip):

The focus for this test is day-to-day activities, you need to know the commands/syntax and not only concepts. Of course, concepts are very important to understand the questions.

What do you need to focus on?
  • OCI-CLI
  • Terraform
  • Policies
  • MQL
  • Quotas
  • What and how you can move Cross-region
  • Budgets and Alerts
  • What is related to Compartments and what is related to the Tenancy
  • Upload and Download files using the cli and the console
  • Tags
  • NVMe - Performance and how to protect
  • Object Storage life cycle
  • VPNs

How to study for 1Z0-997-23 - Oracle Cloud Infrastructure 2023 Architect Professional

Hi everyone,

Well, not all exams. I will do only the ones that I did in 2019 to 2022 and are the things that I work on a day-to-day basis 🙂


This test has a new format, with hands-on questions. Which is great in my opinion :)

After the hands-on, you will need to answer 14 questions (same as previous exam format).


On this test, I expected to see some new things(comparing the course topics with the previous years). And that's true, I got a lot of new questions.

A good starting point is here:


What do you need to focus on? 
  • EVERYTHING :)

Official Documentation:


User guide:


But I recommend you to have a free account and test everything you can! The biggest problem will be testing cross-region features because a free account allows subscribing to only one region.

On ULS, you can also find some examples of questions and they are very helpful in understanding what to expect on the real test. You can see the demos for the hands-on labs.

Take an extra look at the Azure integration with OCI.



Extra tip: Don't be Alex and waste some precious time. Remember to set the correct network on the Cloud Shell console. It will help you with testing :)

If you are not finding available slots until August/31, just keep trying.

Hi everyone,

On this test, I was not expecting to see new things, since the 2022 exam is very recent. But unfortunately, it was not true, I got a lot of topics not covered in the videos and especially on the PDFs. 

This exam consists of 55 questions and you have 1.5 hours.

If you have ULS, this is a good starting point:


These are good documentation to read and understand the concepts:

You can also find some examples of questions in this link and they are really helpful to understand what to expect on the real test.

Review the exam topics, everything will be at the exam:



1st attempt:

2nd attempt:



One interesting thing about his test, if you go to the Oracle official practice test, you will find a lot of questions that you will not find the answer in Oracle's material/documentation. And the worst part, you can find these answers on AWS, GCP, AZURE, and to my surprise, Alibaba Cloud.


And last but not least, stay away from Brain Dumps!
