Featured Reviews

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 find the performance features of Oracle Database In-Memory to be most beneficial."
"The application development is very user-friendly."
"Normally, every database server uses hard disks. In-Memory has a feature, apart from their database, which is very good. When we start our server, all your data needs loading memory. We can use that. It's a very good feature. I think they added this feature in 2019. We can mount memory in the partition, create partitions in there, and create table space from that spot to share. It's a really good feature. We use it a lot."
"The most valuable aspects of this solution are the fast caching and improved performance to the database"
"We find the dashboard and the speed of data processing very valuable in Oracle Database In-Memory."
"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."
"It efficiently handles low-code data and supports read-and-write operations for clustering."
"It has a programming language so anything that we require for Selenium is all available there."
"The database is quite robust in terms of performance from the SQL side."
"There have been no issues in relation to stability. We've never really had do to any recoveries. It is very stable."
"The additional value of having Java inside the Oracle database is all the security that is applied to an Oracle database will be enforced on Java's stored procedures as well."
"The solution is stable."
"It's very clever."
"The most valuable feature is automation."
"Able to write queries more efficiently and the management of data has become better and easier."

"Technical support is below our expectations currently. It could be improved."
"The pricing could be improved. It would ideal if it was more reasonable."
"The dashboard requires some refreshment or configuration improvements."
"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"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."
"The high cost of the product is an area of concern where improvements are required."
"Needs improvement in consistency issues with respect to timeframes."
"The tool might be integrated, but we see performance issues because of overhead."

"The solution could be more user-friendly."
