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

"Database In-Memory, to me, is the most compelling reason to go to Oracle 12c, release 1."
"It accelerates query processing, which in turn speeds up operations and streamlines workflow, and ultimately enhancing productivity."
"I cannot imagine IT today without Oracle databases."
"We find the dashboard and the speed of data processing very valuable in Oracle Database In-Memory."
"We are using Oracle Database In-Memory as an indirect approach to improving response times, and in mixed-workload environments, we use the In-Memory column store to support OLAP-type queries without harming the latency-critical OLTP operations the systems earn money with."
"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."
"Overall, it's a very good solution."
"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."
"This is a fairly stable language, and it's been in the market for several years."
"The solution is stable."
"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."
"Our ROI has been a 600% growth in stock price, one of the biggest increase rates for any of the global top 50 companies."
"Using this product will lead to a reduction in operational costs."
"Running queries is the solution's most valuable feature."
"The valuable features include connecting to the database and retrieving data."
 

Cons

"Multitenant, to be honest, is a little adolescent at this point."
"You need to have platinum service to get good support. Otherwise, you'll have to struggle a bit."
"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
"For some reason, the stats optimizer doesn't work well. We had to disable some of the Oracle’s new features that are not quite mature."
"The high cost of the product is an area of concern where improvements are required."
"The query optimization and backup features should be added."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"In the next release, Oracle should include column store or advanced query optimization so a database can be optimized by enabling analytic queries to run faster."
"It'll be better if Oracle Java supports open source technologies, like Node.js."
"The biggest lesson that I have learned from using Oracle products is vendor lock-in."
"Needs improvement in consistency issues with respect to timeframes."
"With respect to the product's consistency, there's a lot of scope that could be introduced in regulator basis."
"The solution could be more user-friendly."
"Oracle can improve by providing more connection string variations and relay servers on the path to the database."
"The solution should continue to keep updating and improving the Java language."
"In terms of improvement, I'd like an automation tool that is lower priced. The core prices are very high."
 

Pricing and Cost Advice

"Database In-Memory is priced a bit higher than its competitors like Microsoft."
"I rate the pricing a zero out of ten because Database In-Memory is too costly."
"The pricing is pretty good so I rate it an eight out of ten."
"There is a need to make a yearly payment towards the licensing costs, after which there is any to pay towards the support cost attached to the solution."
"The solution's pricing is high."
"It's quite costly and it comes with a fixed price."
"The product is expensive."
"The platform's licensing cost needs improvement."
"The product's pricing is very friendly, with no extra costs after the licensing fees."
"Oracle Java DB is a pricey solution."
