Executive SummaryUpdated on Mar 4, 2025

IBM Db2 Database and Oracle Database In-Memory compete in the enterprise database management category. Based on the comparison, IBM Db2 seems to have an advantage in flexibility and integration, whereas Oracle leads in speed and performance for analytics.

Features: IBM Db2 Database offers a versatile SQL dialect with object tables, Java method support, and user-defined functions. Its broad platform support provides flexibility across diverse environments, and its self-tuning memory management optimizes performance automatically. Oracle Database In-Memory is recognized for real-time analytics capabilities and fast performance in data warehouses due to its columnar format for queries. Its multitenant features facilitate easy database consolidation and cloning.

Room for Improvement: IBM Db2 faces challenges with a steep learning curve and difficulty in finding skilled administrators. Licensing complexity and costs are additional concerns, and there is a need for improvements in the database management interface and backup processes. Oracle Database In-Memory could improve its pricing models and adaptability, making costs lower and more automation in analytics desirable, especially for smaller businesses. AI integration and user interface enhancements are areas for both products to consider.

Ease of Deployment and Customer Service: IBM Db2 primarily offers on-premises deployments with some hybrid cloud instances. It provides strong technical support but faces availability issues outside North America. Oracle Database In-Memory offers both on-premises and hybrid cloud solutions. While it has reliable customer service, pricing and technical support may lack transparency. IBM's support is praised for its knowledge, whereas Oracle customers appreciate quick issue resolution.

Pricing and ROI: IBM Db2's pricing is high but offers bundled packages for cost-effectiveness, generally costing less than Oracle and providing better ROI through integrated solutions. Oracle Database In-Memory is known for being expensive despite including significant features in its Enterprise edition. While both systems demonstrate substantial ROI, IBM's pricing is more competitive, whereas Oracle delivers speed and performance at a higher cost.

Very scalable with high availability and excellent technical support

The good thing is that there are improvements coming with later function levels for the z/OS Db2. I'd like it if, with the operating system that we've got, z/OS, on the mainframe, it would allow us to refresh the hardware to run Linux dockers on the mainframe. This means this might give us opportunities for different ways of coming into the Db2 environment in the future. We just want a bit more integration with Linux. That said, we are already seeing Linux more readily available on the mainframe environment. Not only have we got the premium operating systems on OS. We can run LPARs on the same mainframe footprint that is also supporting Linux. This is what has improved and made the mainframe environment more competitive. We're also looking at AI for Db2 as well, and machine learning for the future. We know that AI has come out, that we're going to get that, and we're going to evaluate that product next year for Db2. That said, I haven't got any real complaints about Db2 on the mainframe. For the most part, a lot of the problems we have nowadays are to do with communication between the various teams that you would class as stakeholders.

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

"The most valuable features are with the industrial side."

"I believe that because the support is good, they jump in and assist us in determining the root cause."

"It has a good feature called pureScale, which is just for scalability. It is a perfect solution for environments where scalability is going to be an issue."

"it is very stable and runs smoothly once it is deployed and it is almost maintenance-free."

"Db2 Database has given us good results since we have started to use it. We predominantly use IBM hardware, and this is one of the reasons why we started to use Db2 Database. Db2 Database has a very good HADR capability. High availability resilience is also good in this solution. It also has pureScale, which allows you to upgrade one node to get very good and high-level resilience. If you are using a database on five nodes, you can take one node down, upgrade that, and let that node up. You can then bring the second node down, upgrade that, and so on."

"Scalability-wise, I rate the solution a nine out of ten."

"The solution is very stable, in both hardware and database."

"The solution's initial setup is straightforward."

More IBM Db2 Database pros

"The solution is very fast."

"Oracle Database In-Memory is a suite of features that improves performance for real-time analytics and mixed workloads."

"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."

"The on-premise version is stable. We have different teams and resources for the server side, for admin, and for development. We can easily take care of all the services and applications."

"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."

"I like Oracle because it is a backward-compatible solution."

"The most valuable aspects of this solution are the fast caching and improved performance to the database"

"The scalability of the solution is very good. It's able to support large amounts of data."

More Oracle Database In-Memory pros

Cons

"It would be ideal if the solution offered backup functionality. Many similar tools already do, which means Db2 is somewhat behind the curve in terms of what a customer might expect from it."

"The solution's UI hasn't been upgraded. The solution’s UI is an area to improve because the solution was developed long ago."

"The application development requires a Java developer and not every company has these resources."

"I would say that the tool has to be made more cloud-friendly and should have agreements with AWS, Microsoft, or Google to run things on hyperscalers."

"The initial setup could be improved."

"IBM's support isn't as strong as it used to be, especially when it comes to providing fixes."

"IBM's products tend to be quite costly, especially given the availability of free, open-source alternatives."

"The data table names are very short which is not user-friendly compared to the Oracle SQL server. It should have longer column and table names."

More IBM Db2 Database cons

"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."

"I would like Oracle Database In-Memory to include a data replication feature."

"They should improve the solution's scalability for large databases."

"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."

"The solution should move to the new way of writing software code with AI that is intelligent and learns."

"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."

"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."

"Technical support is below our expectations currently. It could be improved."

More Oracle Database In-Memory cons

Pricing and Cost Advice

"Licensing fees are on a yearly basis."

"The solution's pricing is fine."

"It's very expensive."

"It is expensive when compared to other products."

"We normally handle large size businesses and as far as I am aware, the license is negotiable based on the number of users and the quantitative data."

"It's very expensive for West African countries like ours."

"It is expensive. The price depends on the size of the machine on which you are installing the Db2 and the features you are using. It also depends on the country. IBM has different policies and different options for payment for this product."

"Db2 is less expensive than Oracle."
