Hosney Osman - PeerSpot reviewer
Technical Solution Architect at Vodafone
Real-time analytics have transformed response times and support huge data volumes with compression
I do not have any comment related to the improvement of the solution; for sure, it needs improvement, but for my use cases, it is very sufficient, and I think for the biggest companies, it needs a very powerful infrastructure. The area where improvement is required the most in the product is the UI. The problem with the UI is that it is not complex for understanding, but it needs some training to know what each button does, how it works, and the many variables needed.
Anil-Sinha - PeerSpot reviewer
Senior Consultant at a tech vendor with 10,001+ employees
Able to process all the reporting and processing in the database itself
We have been upgrading and moving to new environments. I was involved in the solution's initial setup. Some things in the setup are very smooth sailing. However, some setups become complicated because what they set up doesn't meet your needs. So, some tweaking is necessary in certain instances. Having a good understanding of the tool really helps. Oracle Java DB is easy to deploy if it's a new setup. Migrating from an old environment to a new environment takes time because you need the old functionality. A first-time deployment of the application is easy. We just did a default setup and started using it. When we have to migrate, there is too much baggage behind that application, especially from the security point of view.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution's ROI is excellent."
"I've been an Oracle customer with different companies, and one of the key things that stands out for Oracle is the support, because I also work with other database vendors and that's the biggest differentiator."
"The solution is very fast."
"We find the dashboard and the speed of data processing very valuable in Oracle Database In-Memory."
"We can provide a high standard with this solution to our customers by using such products."
"The valuable features of Oracle Database In-Memory include its capability to bypass disk storage for faster memory operations, which is critical for transactions and analytics."
"The most valuable feature is that Database-In-Memory is more consistent and faster than traditional databases as it requires fewer CPUs to process instructions."
"Combined with Exadata, it makes a solution that will deliver the best performance related to the volume of data."
"The stability is awesome because it is all supported by Oracle database and Oracle relational database management system, which watches very carefully all the processes that are running, making it very stable and very secure."
"Able to write queries more efficiently and the management of data has become better and easier."
"Using this product will lead to a reduction in operational costs."
"The most valuable feature is automation."

"Our ROI has been a 600% growth in stock price, one of the biggest increase rates for any of the global top 50 companies."
 

Cons

"The dashboard requires some refreshment or configuration improvements."
"Oracle Database In-Memory appliance-based solutions can be restrictive for some applications, as they may require more flexibility in the database design to be tuned and sized to the customer's needs."
"Technical support is useful with the My Oracle Support website. But when I have to open a service request, I have to find a solution on my own because technical support usually doesn't understand my problem or they always ask for the same logs, same questions, and I ultimately waste my time."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"The product could be more economical."
"We often have to find solutions on our own through the support site, so there's room for improvement in this regard."
"We use some partitions in In-Memory. We have a very large table and a low dose. It is very expensive in data to load all of them into In-Memory. It takes up more memory slots in the server, as well as a lot of RAM. We use last partitions on the table. We always need to create a script and make a schedule that can load a last partition in In-Memory. Oracle doesn't have features to do this automatically. I would like them to allow us to load last partitions, as well as other table partitions, in In-Memory. I think a good feature would do that automatically, letting you see a table, load a large partition, and monitor loading memory. It's quite a good feature."
""It depends". If you get a good support engineer, it is a dream. But, most times, it is not, unfortunately."
"The solution could be more user-friendly."
"It'll be better if Oracle Java supports open source technologies, like Node.js."
"With respect to the product's consistency, there's a lot of scope that could be introduced in regulator basis."
"In terms of improvement, I'd like an automation tool that is lower priced. The core prices are very high."
"In terms of improvement, I'd like an automation tool that is lower priced. The core prices are very high."
"The biggest lesson that I have learned from using Oracle products is vendor lock-in."
"The solution should continue to keep updating and improving the Java language."
"The solution could be more user-friendly."

"Database In-Memory is priced a bit higher than its competitors like Microsoft."
"The solution's pricing is high."
"The product is expensive."
