Nicolae Ancuta - PeerSpot reviewer
Strong event capabilities, allowing raising and displaying events in applications
On large databases, we have some difficulties. It is one of the areas of improvement. For example, under one gigabyte, it works perfectly. Between one and five gigabytes, you might experience some slight performance issues, but they are not significant. Beyond that, you have to index it, tier it, and perform some restore operations to free up space. It requires some effort, but it's manageable. It's quite challenging for the customer. Moreover, migrating from one firewall solution to another was a little bit difficult regarding the backup and restoring the other one. Since we have many databases, we didn't go forward with the latest versions.
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.

Cons

"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."
"Oracle should include column store or advanced query optimization so a database can be optimized by enabling analytic queries to run faster."
"The solution should move to the new way of writing software code with AI that is intelligent and learns."
"They should improve the solution's scalability for large databases."
