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.

Database has secured high-volume transactions and supports fast, compliant workflow processing

Sterling B2B Integrator is a highly transactional-oriented application, which can be described as an OLTP application. Any data that flows through the application is stored in the database for each step that it performs. IBM Db2 Database helps the application work much faster from an OLTP perspective. IBM Db2 Database is SSL enabled, which means that from the security point of view, any access to the database is through SSL. Additionally, all compliance-related aspects have been taken care of from the database point of view, including database encryption and security-related features. It is highly scalable, and its performance related to database pruning is very good. It can be scaled vertically or horizontally so that data insertions and data access are much faster and more secure compared to how Oracle or other databases work.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"This solution is scalable, we have an infrastructure that is based on virtual machines so we can add more to grow as we need, and I am very happy about that."

"I'm using this solution for a financial network; I make and prepare the databases for analysis."

"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 product is very reliable and stable, and we used to receive prompt responses from IBM on support."

"Db2 is a robust relational database with great features."

"IBM’s DB2 is a robust relational database management system (RDBMS)."

"The solution is a very stable relational database and has integration with legacy systems. It is a great product."

More IBM Db2 Database pros

"Our ROI has been a 600% growth in stock price, one of the biggest increase rates for any of the global top 50 companies."

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

"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 solution is stable."

"This is a fairly stable language, and it's been in the market for several years."

"The solution's capability to handle large data sets, large volumes and indexing are the most valuable features."

"Running queries is the solution's most valuable feature."

"It's very clever."

More Oracle Java DB pros

Cons

"The initial setup could be improved."

"The management of Db2 should be simplified because there are not too many specialists in this area, and the learning curve of Db2 specialists is very long."

"The solution no longer supports POWER8."

"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."

"We just want a bit more integration with Linux. That said, we are already seeing Linux more readily available on the mainframe environment."

"We need some time to improve the performance. We have to perform a weekly REORG, or else RUNSTATS for the databases."

"The queries can be difficult for beginners because there are so many. I would like to see more use cases for flow analysis that enable us to correlate the flow with events. Adding this feature in a QI format would be good for beginners."

"The product needs to improve its configuration and storage."

More IBM Db2 Database cons

"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."

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

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

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

"The solution could be more user-friendly."

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

"With respect to the product's consistency, there's a lot of scope that could be introduced in regulator basis."

More Oracle Java DB cons

Pricing and Cost Advice

"The solution's pricing is fine."

"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."

"Db2 is less expensive than Oracle."

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

"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."

"Clients are required to purchase a license."

"I would rate the pricing a five out of ten. It's not super expensive, but also not cheap."

More IBM Db2 Database pricing and cost advice

"Oracle Java DB is a pricey solution."

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