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.

Quotes from Members

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

Pros

"Replication is a valuable feature and easy to use."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"The most valuable feature is concurrency and locking because my customers usually use databases in OLTP mode. So, for a large number of competitive users. Other features that are well valued are quick large-scale data types. It is better than Oracle."
"The stability is incredible. I have customers with uptimes of several years."
"The scalability is very good."
"Replication, all levels of replication, query charting, and the MongoDB embedded are the most valuable features of this solution."
"So far, we do not have a lot of issues. It's pretty problem-free."
"It supports multiple applications and business intelligence tools."
"The scalability is very good."
"The most valuable aspects of this solution are the fast caching and improved performance to the database"
"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 solution is very fast."
"Security is the most valuable feature."
"The scalability of the solution is very good. It's able to support large amounts of data."
"We can integrate it with any data sources as well."
"The solution's ROI is excellent."
 

Cons

"The solution really doesn't add new features very often."
"The solution lacks some functionality."
"This solution is in need of more current tools."
"I really would love to have a QT plugin."
"The technical support services need substantial improvement."
"In my opinion, the packages could be improved. The version I use doesn't allow for packages. I can do some general procedures, but no packages like in Oracle. So, develop separate modules in SQL language. This would be most beneficial for me."
"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"We often have to find solutions on our own through the support site, so there's room for improvement in this regard."
"Oracle Database In-Memory could improve by better supporting generative AI challenges, such as hallucination management."
"The high cost of the product is an area of concern where improvements are required."
"Technical support is below our expectations currently. It could be improved."
"The product could benefit from enhancements in its graphical user interface."
"Oracle should include column store or advanced query optimization so a database can be optimized by enabling analytic queries to run faster."
"The solution is quite expensive."
"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."
 

Pricing and Cost Advice

"For me, it's always too expensive."
"I am not aware of the licensing costs or terms."
"The product has reasonable pricing. We purchase its yearly license."
"The free edition can be enough to handle moderate-size implementations, but you may want a pay for edition to benefit from more functionality, such as replication."
"The product is expensive."
"The solution's pricing is high."
"Oracle Database In-Memory is expensive."
