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."Provides good security and reliability."
"The solution is stable."
"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."
"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."
"The standout feature of IBM Db2 Warehouse, which is particularly valuable for large enterprises, is its ability to handle big data."
"Some of the best features are stored procedures, parallelism, and different indexing strategies."
"The analytics engine is not bad at forecasting predictions."
"We like the tool’s features like Smart Scan, Hybrid Columnar Compression, and the TFA."
"The most valuable feature of Oracle Exadata is the storage available."
"The offloading of data to the SIM is a valuable feature."
"On-premises Exadata is just as stable as the cloud version. It's a very stable platform."
"What I like best about Oracle Exadata is its good performance. It's also a very fast solution."
"The performance on the databases is good."
"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."
"The tool's performance is good."
"In terms of improvement, IBM Db2 Warehouse should be more scalable."
"IBM Db2 Warehouse needs to improve its interface."
"The areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."
"Lacks sufficient documentation and particularly in Spanish."
"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."
"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 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."
"There is room for improvement with the handling of the Temp IO, which is often used for JOIN statements."
"Tech support sometimes takes some time to identify and rectify issues."
"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."
"The integration with third-party applications regarding access management security could be better."
"I would like to see more database features and maybe more archiving features, because we need to do data archiving."
"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."
"The analytics features must be improved."
"I believe Oracle must improve its procedure to support the clients. The customer Ready Service must provide more use cases and benchmarks of their infrastructure to support client design decisions. Oracle must audit their partners regularly to guarantee they provide quality service even after been passed on partnership examination."
