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.

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.

"We had a crash of the backup system and the IBM DB2 was always up and consistent. It's robust, and for us, it was always up and running."

"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."

More IBM Db2 Database pros

"It's very clever."

"There have been no issues in relation to stability. We've never really had do to any recoveries. It is very stable."

Cons

"IBM Db2 Database is not ACID compliant, which would improve it. Db2 lacks Isolation, so when two people are trying to update the same field at the same time it can become stuck. Other newer databases do not have this issue, such as Microsoft SQL, Oracle DB, PostgreSQL, and SAP HANA."

"Not very solid compared to its competitors' products."

"End-to-end encryption specifically is something the solution needs to have in the next release."

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

"The vendor should offer a free version"

"Db2 interface could be improved a bit. Comparing it to Oracle, Db2's interfaces could be improved."

"IBM Db2 Database could improve with better security."

"Some of the internal rearrangement in the administration is not as straightforward as it is in competing products."

More IBM Db2 Database cons

"In terms of improvement, I'd like an automation tool that is lower priced. The core prices are very high."

"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 biggest lesson that I have learned from using Oracle products is vendor lock-in."

"The solution could be more user-friendly."

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

"It'll be better if Oracle Java supports open source technologies, like Node.js."

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

Pricing and Cost Advice

"Licensing fees are on a yearly basis."

"If I consider the price of IBM Db2 Database, I would say there are cheaper products in the market."

"I think that everyone knows that with IBM the standard price is higher than the others."

"There is a license for this solution and we pay every three years."

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

"Clients are required to purchase a license."

"It's very expensive."

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

More IBM Db2 Database pricing and cost advice

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