Laksiri Bala - PeerSpot reviewer
Faster processing and improved memory operations have enhanced transaction and analytics efficiency
The valuable features of Oracle Database In-Memory ( /products/oracle-database-in-memory-reviews ) include its capability to bypass disk storage for faster memory operations, which is critical for transactions and analytics. It also offers specific memory areas, like in-memory cache, that act as intermediaries between disk and buffer cache. This feature helps organizations handle real-time memory requirements effectively.
Anil-Sinha - PeerSpot reviewer
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

"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."
"I find the performance features of Oracle Database In-Memory to be most beneficial."
"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 solution's ROI is excellent."
"We use the tool for real-time data transfer for risk management purposes. In a trading system, conversions happen fast. We use the product to handle fast transactions with low latency."
"The most valuable aspects of this solution are the fast caching and improved performance to the database"
"The solution's most valuable feature is its performance optimization within our hardware environment."
"Security is the most valuable feature."
"It's very clever."
"The database is quite robust in terms of performance from the SQL side."
"The valuable features include connecting to the database and retrieving data."
"The solution is stable."
"Able to write queries more efficiently and the management of data has become better and easier."
"There have been no issues in relation to stability. We've never really had do to any recoveries. It is very stable."
"It has a programming language so anything that we require for Selenium is all available there."
"The most valuable feature is automation."
 

Cons

"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."
"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."
"The pricing could be improved. It would ideal if it was more reasonable."
"Oracle should include column store or advanced query optimization so a database can be optimized by enabling analytic queries to run faster."
"The product could be more economical."
"Technical support is below our expectations currently. It could be improved."
"The high cost of the product is an area of concern where improvements are required."
"In terms of improvement, I'd like an automation tool that is lower priced. The core prices are very high."
"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."
"The solution could be more user-friendly."
"The tool might be integrated, but we see performance issues because of overhead."
"The solution should continue to keep updating and improving the Java language."
"Needs improvement in consistency issues with respect to timeframes."
"Oracle can improve by providing more connection string variations and relay servers on the path to the database."
