We performed a comparison between IBM Db2 Warehouse and Oracle Exadata based on real PeerSpot user reviews.
Find out in this report how the two Data Warehouse solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It can be mounted on the cloud, which is a huge plus. If the client, for example, starts small with on-premise deployment and then it rapidly needs to grow, we can transfer this to the cloud easily."
"Some of the best features are stored procedures, parallelism, and different indexing strategies."
"The solution is stable."
"The analytics engine is not bad at forecasting predictions."
"Provides good security and reliability."
"I think it scales really well and as long as you take enough time to learn a little bit about it, it works really well."
"The standout feature of IBM Db2 Warehouse, which is particularly valuable for large enterprises, is its ability to handle big data."
"Compression is a great feature, where one can really save a lot of storage."
"The performance on the databases is good."
"The tool's performance is good."
"They just have a lot of products, and they work well together."
"The new Exadata x9m has an even higher speed of 100GBps connectivity."
"This product can noticeably enhance performance of contextual Oracle databases."
"It offers a significant advantage for accommodating a large number of users."
"Before using this machine, we took no less than two days to run a report. Now, we can do it within five hours. So, there is a lot of improvement."
"There should be more material available for training and training should be free."
"There were some initial challenges with IBM Db2 Warehouse about eight months ago when I worked in this environment. When I coordinated with IBM support, they mentioned that the memory was insufficient for our needs. Our business environment required significantly more memory than the previous cluster could provide. Consequently, we have worked closely with on-site IBM technical personnel to address this issue."
"The areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."
"The biggest challenge anyone could have with Db2 Warehouse is their references or online resources and documentation. They are very, very, very limited on the web."
"Lacks sufficient documentation and particularly in Spanish."
"In terms of improvement, IBM Db2 Warehouse should be more scalable."
"IBM Db2 Warehouse needs to improve its interface."
"The biggest problems we have is when the backup solution is failing or slow and we run out of log space, which has happened probably a couple of times in the last four years."
"Oracle Exadata could improve the platform performance tuning should be easier, automated, and user-friendly."
"The setup is a little bit complex. We would like to see the installation part get easier."
"The improvement could be made on the hardware level as the habit in the industry is to go better and faster and larger with every iteration."
"It is difficult to evaluate return-on-investment because of the way billing is handled for the product. This should be improved by oracle."
"The solution lacks a visualized console."
"Sometimes it takes too long time to get help with technical issues."
"There is one aspect to Exadata that I dislike, and that's the inconsistency with other databases. When you try to get Exadata to function with another type of database like SQL, or others, there should be reliable and consistent operation. When this is improved on, we should start to see more applications growing the market."
"In a future release, I would like to see some upgrade analysis advisors to help with a clear roadmap on steps that need to be taken and some of the automated processes."
