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 analytics engine is not bad at forecasting predictions."
"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."
"Provides good security and reliability."
"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."
"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."
"Exadata's best features are its performance during redo logging and the elasticity of the database handling."
"The most valuable feature is storage offloading."
"They just have a lot of products, and they work well together."
"We can use virtualization on Exadata."
"The data replication is very good."
"Backup/Restore performance: Fast backups, fast restores (especially useful for creating clone environments)."
"The most valuable feature is the time to solution."
"The most valuable feature of Oracle Exadata is its capabilities for storing and processing data. It is very good for our domain."
"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."
"In terms of improvement, IBM Db2 Warehouse should be more scalable."
"There should be more material available for training and training should be free."
"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."
"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."
"The scalability can be improved as it is not a parallel execution."
"License or upgrade management can be difficult and time consuming because it requires login to a separate console."
"Patching must be simplified."
"Certification should also be improved. Today, Oracle doesn't certify applications with engineered systems."
"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 performance could be improved."
"The technical support is in need of improvement."
"Tech support sometimes takes some time to identify and rectify issues."
