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.

Cons

"The technical support services need substantial improvement."

"The support team could include local engineers to establish efficient communication. It will help us speed up the escalation process."
"This product could be made easier to use for beginners."

"It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM."
"The pricing is a bit expensive."
"The pricing could be improved. It would ideal if it was more reasonable."
"Oracle Database In-Memory is more expensive than Azure, and the support from the Oracle team is not very good, especially since they do not have a support team in our region."

"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"The high cost of the product is an area of concern where improvements are required."
"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."
"I would like Oracle Database In-Memory to include a data replication feature."
