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."
"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."
"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 analytics engine is not bad at forecasting predictions."
"Provides good security and reliability."
"Oracle Exadata has very good hardware."
"What I found most valuable in Oracle Exadata is its newer technology that gives better performance. It has more recent hardware and significant changes in the architecture, so it's better than older solutions."
"The business intelligence is very good."
"It is a highly relevant option with extreme performance."
"Complete management occurs from one single address instead of different servers."
"Oracle Exadata's performance is one of its best features. We very satisfied with it."
"Compression is a great feature, where one can really save a lot of storage."
"Exadata is a fantastic machine. Two features stand out. The first is the resource input/output management tool that allows you to manage the resources to the neck on the Exadata box."
"Lacks sufficient documentation and particularly in Spanish."
"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."
"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."
"In terms of improvement, IBM Db2 Warehouse should be more scalable."
"Patching must be simplified."
"We have a little trepidation with the system as it does have a learning curve. Also changing to a binary logging format for us feels like retrograde motion, but sadly almost all Linux variants have moved in this direction."
"Sometimes it takes too long time to get help with technical issues."
"The cost of the solution is high and can be improved."
"We need a monitoring tool which can in one place, where we can manage, monitor the entire Exadata components."
"Oracle Exadata could improve by having faster data retrieval. We receive data at four or five seconds and want to reduce that number to one second."
"Exadata would be improved with single dashboard visibility."
"The performance could be improved."
