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."The standout feature of IBM Db2 Warehouse, which is particularly valuable for large enterprises, is its ability to handle big data."
"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 solution is stable."
"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 analytics engine is not bad at forecasting predictions."
"Provides good security and reliability."
"Some of the best features are stored procedures, parallelism, and different indexing strategies."
"Exadata's best features are its performance during redo logging and the elasticity of the database handling."
"The data replication is very good."
"Oracle is known to be the number one in their industry; the help and support, the features they are giving the clients comparing to other databases, the new technology, the provide a good solution."
"Parallelism is the most valuable feature."
"The storage capacity and the performance of Oracle Exadata are good. When comparing the performance to other technologies it is very good. I am satisfied with the management of the solution."
"It is a scalable solution."
"The new Exadata x9m has an even higher speed of 100GBps connectivity."
"The business intelligence is very good."
"There should be more material available for training and training should be free."
"In terms of improvement, IBM Db2 Warehouse should be more scalable."
"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."
"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."
"IBM Db2 Warehouse needs to improve its interface."
"Lacks sufficient documentation and particularly in Spanish."
"The performance could be improved."
"Exadata would be improved with single dashboard visibility."
"The solution could always be more stable and more reliable."
"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."
"I liked Spark, but it was discontinued when Exadata L6 came back. I loved it, and I wish they would bring back Spark integration."
"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."
"There is room for improvement with the handling of the Temp IO, which is often used for JOIN statements."
