Identify specific production scenarios—ranging from massive data lakes to low-latency financial transaction workloads—where deploying an autonomous cluster fits.
Before Moving to Oracle Autonomous Database, Ask These 8 Questions
A critical assessment guide for data leads. Learn to validate legacy feature support parameters, isolate schema locks, and analyze sizing handles before executing migrations.
Migrating into Autonomous Database is a different contract, not a smaller migration — no DBA shell, no manual tablespace tuning, and a compatibility check before you commit.
A deep dive into what GoldenGate Extract actually reads, how trail files are structured, and how Replicat applies changes — beyond treating it as a black-box migration tool.
Two teams migrate similar 2TB databases — one uses Data Pump and takes an 8-hour outage, the other uses GoldenGate and cuts over in under 5 minutes. Here's how to choose.
A 100GB database and a 100TB database moving to the same ExaCC target need completely different migration strategies — size, bandwidth, and SLA together decide the method.
Moving a database platform and upgrading its version used to mean two separate projects with two outages. A Data Guard-based physical online migration combines both.
At 500GB either tool works — at 50TB, only one finishes before the maintenance window closes. A practical comparison of RMAN duplicate and Data Pump for VLDBs.
The migration completes, the database opens, and every encrypted tablespace throws ORA-28365. The data moved — the encryption wallet didn't. Here's how to avoid it.
A DBA spends three weekends hand-scripting an RMAN duplicate, Data Guard switchover, and rollback plan. Oracle ZDM does the same migration, unattended, with built-in safeguards.
Moving a multi-terabyte database from Solaris SPARC to Linux x86-64 sounds like a days-long export/import project. Cross-Platform Transportable Tablespaces change that math.
ZDM is often described as a wrapper around RMAN and Data Guard — true but incomplete. Its real value is a phase-based workflow engine with full REST API automation.
Honest feedback from professionals and learners who have been part of the ExaGuru learning journey.
Excelent Online training institute for Exadata, Exacc and OCI
Excelent Online training institute for Exadata, Exacc and oci. I had a great learning experience. Special appreciation to Mr. Krishna for his outstanding teaching skills. His clear explanations, practical approach, and ability to simplify complex technical concepts made the training easy to understand and follow. I highly recommend this institute to anyone looking to enhance their knowledge and skills in Oracle Exadata, ExaCC, and Oracle Cloud Infrastructure (OCI). Thank you, Mr. Krishna, for the excellent training and guidance!

It's very good platform to upgrade your skills
It's very good platform to upgrade your skills in very less time with hands-on practical knowledge as theory is not sufficient enough to upgrade your skill. Krishna has very good knowledge on what's actually needed to stay in market. What is essential which keeps you demanding in job market.

Excellent Course with Real-Time Troubleshooting
My experience with the ExaGuru course has been very positive and valuable. The training covers Exadata, OCI, ExaCC, and ExaCS in a practical and easy-to-understand way. The instructor (Krishna Sir) explains the concepts clearly and provides real-time industry examples, which helped me understand how these technologies are used in production environments. The hands-on lab sessions were especially useful because they gave me an opportunity to practice the concepts and gain practical experience. The course also covers real-time troubleshooting scenarios, which is very helpful for understanding and resolving issues that can occur in production. The recorded sessions are another great advantage, as I can revisit the topics whenever I need to refresh my knowledge. The job portal support provided as part of the course is also very useful for exploring relevant career opportunities. Overall, the combination of theoretical knowledge, real-time examples, hands-on practice, troubleshooting, recorded sessions, and job support has made this course very useful for my career and practical knowledge.

Quite literally the most in dept educational content available for Orcale ExaData
Well I scoured the internet for in depth ExaData courses and couldn't find any then I stumbled upon Exaguru was a bit skeptical at first but got enough confidence in their webinar and the best part of these courses were the interactive labs we were actually learning through practical application which is leagues and miles ahead of any other educational offering for these courses particular courses and the labs coupled with one on one doubt session helped me to actually get a job because their syllabus is quite tightly aligned to what is asked in and needed in the industry.

The finest Exadata training I found
I found Exaguru while checking all the other options available for Exadata training, and found their training program the finest among all. They have a structured approach to the subject and know exactly whats needed in the industry in today's times. They even provide real time simulators, which is as-good-as practising on a real exadata machine, which is too expensive to procure for training. Viraj, our trainer, is an excellent teacher and has his own ways to motivate and assist in learning the fundamentals. Im happy to be part of exaguru and would recommend them to whomsoever is looking to learn Exadata and OCI.
