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."Some of the best features are stored procedures, parallelism, and different indexing strategies."
"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 solution is stable."
"The standout feature of IBM Db2 Warehouse, which is particularly valuable for large enterprises, is its ability to handle big data."
"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 performance of the data is the most important part."
"The most valuable feature of Oracle Exadata is the smart scan. We have large TB sessions of approximately 100 per second for each of our three instances. The smart scan allows us the obtain data in time in the enterprise manager."
"We can use virtualization on Exadata."
"Oracle Exadata has very good hardware."
"Compression is a great feature, where one can really save a lot of storage."
"This product can noticeably enhance performance of contextual Oracle databases."
"Oracle Exadata is stable."
"The technical support team are real professionals. I admire their technical skills and supports. Their supports are really admirable."
"IBM Db2 Warehouse needs to improve its interface."
"In terms of improvement, IBM Db2 Warehouse should be more scalable."
"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."
"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."
"Lacks sufficient documentation and particularly in Spanish."
"I have found Oracle Exadata to be scalable. However, you have to purchase more hardware, such as memory."
"Oracle Exadata compatibility with the analytics could be better and the OBIEE could improve. Oracle BI to Exadata needs to be improved. Even if the full analytics practice for Oracle should be improved and when compared with other solutions it is weak."
"There is a feature for security, but it is not included in the first purchase of this solution. That means if you need to increase the security, you need to buy the security feature which doesn't come by default on these solutions."
"Certification should also be improved. Today, Oracle doesn't certify applications with engineered systems."
"Oracle Exadata could improve the platform performance tuning should be easier, automated, and user-friendly."
"There is room for improvement with the handling of the Temp IO, which is often used for JOIN statements."
"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."
"The solution takes a lot of time to clone the environment. I would like to see some improvement in the cloning support or the time it takes on the storage side."
