"The solution is a very stable relational database and has integration with legacy systems. It is a great product."
"Its robustness, scalability, availability, and performance are valuable. All these are the major attributes of a relational database for supporting a very high-volume business, and Db2 is very good in all those areas and in all those attributes."
"IBM Db2 Database has good performance."
"Your iOS, your throughputs, your performance cycles, you cannot touch it with Microsoft or with Oracle scalability-wise. That is far and away the most scalable systems and the highest performing systems of the set of them."
"Very good for performance and scalability."
"Reliable, robust with great features."
"The most valuable feature is PowerPC support."
"I like that its true active-active. For example, if there are two instances within a cluster, we can take one of them down and there's no failover or switch over. There's no primary and secondary, it's true active-active. We can take one side down and we can upgrade that with new maintenance or a new version, obviously testing coexistence beforehand, without impacting the business."
"The scalability is very good."
"Replication is a valuable feature and easy to use."
"For IoT business cases, having Informix Enterprise Edition work on edge computers, like Raspberry Pi and using Informix replication, makes complex situations simple to build and maintain."
"The stability is incredible. I have customers with uptimes of several years."
"The initial setup is pretty easy."
"The solution's stability, performance, enhanced functionality, and replication are all great features."
"So far, we do not have a lot of issues. It's pretty problem-free."
"They should simplify the management of Db2 as a relational database system. There should be the simplification of management. This is probably one of the most important asks for being successful in the future."
"The solution could improve by providing more integration."
"We just want a bit more integration with Linux. That said, we are already seeing Linux more readily available on the mainframe environment."
"GUI needs improvement."
"Their view of it is they're maintaining it, they're continuing to upgrade it, they're continuing to grow it, however, they don't go out and try and sell that as an architectural solution the way they do Linux and Unix."
"The only drawback that we see in Db2 Database is the crash recovery. When there is a crash and somebody has to do the recovery, Db2 Database first stops, and then it does any crash recovery. In Oracle Database, crash recovery happens within the database. The database is not shut down."
"Performance is something that can be improved with DB2."
"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."
"This product could be made easier to use for beginners."
"There should be more intelligence surrounding discovering data to be able to automatically create indexes."
"The solution really doesn't add new features very often."
"The solution lacks some functionality."
"The pricing is a bit expensive."
"Continue extending the SQL language for compatibility with the competition's language, including Stored Procedure Language."
"I would like to see backups from secondary servers."
