Executive SummaryUpdated on Mar 4, 2025

IBM Db2 Database and Oracle Java DB compete in the database management space. IBM Db2 has a potential advantage with its pricing and extensive support, while Oracle Java DB is appealing for its advanced functionalities.

Features: IBM Db2 Database offers optimized performance, robust security measures, and integration with AI capabilities. It supports multiple platforms and provides a powerful SQL dialect with object tables and Java method support. Oracle Java DB integrates seamlessly with Java, has lightweight operations, and offers great portability for developers who prioritize simplicity and flexibility.

Room for Improvement: IBM Db2 could improve in terms of initial setup complexity, enhancing user experience with a smoother configuration process. Additionally, simplifying its interface and reducing costs for smaller businesses would be beneficial. Oracle Java DB might enhance its performance under high workloads, increase its scalability options, and offer broader integration capabilities beyond Java, expanding its reach for diverse developer needs.

Ease of Deployment and Customer Service: Oracle Java DB is known for a straightforward deployment process, reducing setup complexities. It aligns with a lightweight service model that focuses on simplicity and rapid deployment. IBM Db2, with its more involved configuration process, compensates through detailed support, ensuring users can navigate the complex setup successfully.

Support improves setup and maintenance while pricing influences decision

If you have a similar use case and the same deal with IBM as our company, it is definitely a good option and choice. The company I work with has more than 50,000 people and more than 500 support staff. We are not locked into one database vendor. We typically work with multiple database vendors simultaneously, selecting the top choice based on the deals we make and other considerations. We do not use IBM Db2 Database related to AI at this moment because our AI project PLC is still very small scale. We may consider it in the future if we have enough scale. Overall rating for IBM Db2 Database is 8.5 out of 10.

Senior Consultant at a tech vendor with 10,001+ employees

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.

"The solution has very good data compression of up to 50%. For example, if you have 50 terabytes of data, it can be reduced to 25 terabytes."

"It has a good, stable performance."

"The most valuable feature of this solution is the integration with other IBM products."

"The most valuable feature of the IBM Db2 Database is the ease of use, and the ability to do query writing of any SQL statement and have an output."

"IBM DB2 pureScale Feature is valuable."

More IBM Db2 Database pros

"Able to write queries more efficiently and the management of data has become better and easier."

"It's very clever."

"The additional value of having Java inside the Oracle database is all the security that is applied to an Oracle database will be enforced on Java's stored procedures as well."

"The valuable features include connecting to the database and retrieving data."

"The database is quite robust in terms of performance from the SQL side."

More Oracle Java DB pros

Cons

"The vendor should offer a free version"

"The licensing fees can be reduced."

"The user interface is not user-friendly."

"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 initial set up was complex."

"IBM Db2 Database could improve with better security."

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

"The command line part of this solution could be much better."

More IBM Db2 Database cons

"The solution could be more user-friendly."

"The solution should continue to keep updating and improving the Java language."

"Oracle can improve by providing more connection string variations and relay servers on the path to the database."

"The tool might be integrated, but we see performance issues because of overhead."

"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."

"Needs improvement in consistency issues with respect to timeframes."

Pricing and Cost Advice

"Compared to other databases, Db2 is relatively cheaper."

"Compared to Oracle, it is so much cheaper."

"We did not buy it. It came with our hardware without any complimentary maintenance. If I compare Db2 Database with Oracle Database, its price is lower than Oracle Database."

"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 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."

"They are competitive and honest (compared to how peer firms approach licensing conversations). "

"The solution's hardware and subscription model for support are very expensive."

"It is expensive when compared to other products."

More IBM Db2 Database pricing and cost advice

"The product's pricing is very friendly, with no extra costs after the licensing fees."
