The TSA version of IBM Db2 Database doesn't meet my stability expectations. Every time when a switch over occurs, some stability issues can be noticed. The vendor should offer a free version of IBM Db2 Database. For instance, if our company wants to train new individuals on all the features of IBM Db2 Database, they can only be trained after purchasing the paid version of the solution. About ten years ago, a trial version was available for the solution that was highly beneficial for companies. The vendor can add AI or ML features in the future version of IBM Db2 Database.

IBM's support isn't as strong as it used to be, especially when it comes to providing fixes. We have to keep track of defects more closely now. When a defect is identified, IBM takes it to their lab, creates an APAR, and provides us with a fix. We receive these fixes periodically and apply them to our Db2 code in a sandbox environment first, not directly into production. We test thoroughly before rolling it out to development and eventually to production. Recently, we've encountered some issues with Db2, requiring us to be extra cautious to avoid outages. Unfortunately, we did experience an outage in February due to a code defect. We recently received a Red Alert from IBM, a critical warning in the mainframe world indicating a potential risk of data loss if not addressed.

Valuable Features

IBM Db2 Database offers robust SQL capabilities, extensive multi-platform support, and self-tuning memory management. Users appreciate its security, stability, performance, and ease of integration with other IBM products. The database's ability to handle complex queries, scalable architecture, and minimal maintenance appeal to enterprises needing high availability and reliability. Its data replication, compatibility, and support solutions enhance its value. Db2 remains favored for its resilience and powerful data management features.

"IBM Db2 Database is perfect and leading in this area."
"I can easily export that to further work on it in Snowflake."
"The valuable features include access path optimization, excellent performance, a robust locking mechanism, parallelism, and effective buffering in memory."

Room for Improvement

IBM Db2 Database experiences difficulty in simplifying management and integration with other platforms. Improving its interface and performance, reducing licensing costs, and enhancing support for cloud and AI features would be beneficial. Ease of use, especially for beginners, along with better pricing and security, also requires attention. Users face challenges with database replication and migration, and they need more intuitive tools and updated training resources. Db2 lacks advanced development features compared to competitors like Oracle.

"It might be slightly slower than other database vendors, but it works well since banks typically do not move quickly with leading-edge technology."
"The user interface is old and needs to be improved."
"The usage of Db2 could be simplified, as it is quite complex and requires substantial knowledge of Db2 and zOS."

ROI

IBM Db2 Database delivers substantial ROI. Organizations report significant financial returns, implementing numerous projects smoothly and earning around 100 billion in their currency. It enhances performance and efficiency, offering considerable long-term financial advantages despite its cost. Users rate it as the best solution from IBM, although some struggle to quantify benefits in numbers. Overall, the investment in IBM Db2 Database proves very rewarding for their operations.

Pricing

Enterprise buyers evaluating IBM Db2 Database note that while it can be less costly than Oracle, it's perceived as expensive compared to other solutions like SQL Server. Licensing complexity and lack of transparency are common concerns, particularly for cloud environments. Mainframes remain cost-effective due to specialized processors and peak usage licensing, reducing expenses. Pricing is influenced by factors such as machine size, usage, and included features. Users highlight potential for bundled discounts when paired with IBM hardware.

"I rate the product pricing a nine out of ten."
"The total cost of the solution depends upon the PVU licensing"
"We purchase the product's yearly license."
