Enhancements in data analysis and decision-making elevate overall performance
The most valuable features of IBM Db2 Warehouse ( /products/ibm-db2-warehouse-reviews ) include its availability, easy integration, ability to deal with a large size of data, excellent performance with no delays, powerful security mechanisms, and effective support. The response time is very quick, and the technical manuals and support from IBM are of high quality. Additionally, it is easy to install, troubleshoot, operate, and secure the environment.
Anand_Kumar - PeerSpot reviewer
A solid data warehouse for transactional data that needs to be priced more competitively
Since the product is an appliance, it is very costly. And in the current age, people are cautious about spending this amount of money on any of these types of backend products. Some use cases are in real-time, where all other databases are much faster, but if you talk about the data warehouse, business intelligence, and all other perspectives in the transactional world, Oracle has to reduce the cost. Otherwise, a customer wouldn't want to continue this. If the same thing can be done at half or one-third of the cost, why would people stay with Oracle? Oracle Exadata would not have great value in front of a CFO. Other solutions can guard your data and address security concerns. Security, volumetrics, and so on are also provided by other databases, which are not that costly. Apart from Exadata, Oracle has other tools for business intelligence and other things, which they add on top of Exadata when they're selling a general license. For example, the Vertica database, an HP data warehouse. They have come up with their own analytic engine within the database, which gives an edge for the client to use the data analytics engine as a part of their database. Exadata does not have an analytic engine. Even MySQL has some statistical tools within it. If Exadata integrates analytical tools, it will be good for them.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution is stable."
"It can scale effectively as long as resources are available."
"The most valuable features of IBM Db2 Warehouse include its availability, easy integration, ability to deal with a large size of data, excellent performance with no delays, powerful security mechanisms, and effective support."
"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."
"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."
"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."
"Provides good security and reliability."
"The analytics engine is not bad at forecasting predictions."
"The tool's performance is good."
"They just have a lot of products, and they work well together."
"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."
"This product can noticeably enhance performance of contextual Oracle databases."
"The tool performs well with a large database."
"Once installed, Exadata is very stable."
"It has improved the performance, now we run with more performance cores with less CPU to attend all the database demands. Reducing Time to Market, increase our ability to face the competition with speed and low cost."
"On-premises Exadata is just as stable as the cloud version. It's a very stable platform."
 

Cons

"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."
"The primary challenges customers face with IBM Db2 Warehouse are related to its complexity in usage. It requires highly skilled professionals who understand Db2, and both training and support are challenging to obtain."
"Responding to support tickets takes a lot of time. It can range from two to four days, even for critical issues."
"It takes a long time to have a new version or release, similar to Oracle."
"IBM Db2 Warehouse needs to improve its interface."
"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 areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."
"The performance could be improved."
"The integration with third-party applications regarding access management security could be better."
"It would be good if Exadata made some new features available regarding data retrieval and speed capacity functions."
"The cost of the solution is high and can be improved."
"I liked Spark, but it was discontinued when Exadata L6 came back. I loved it, and I wish they would bring back Spark integration."
"Patching must be simplified."
"License or upgrade management can be difficult and time consuming because it requires login to a separate console."
"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."
 

Pricing and Cost Advice

"In a traditional on-prem database, in a data warehouse, the solution is probably on the expensive side."
"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."
"The price of Oracle Exadata is competitive. There are some features that are outside of the initial purchase license, such as some monitoring packages."
"Oracle Exadata is not a cheap solution. Pricing is a problem for Oracle, and every client, not just my company, would like the vendor to improve on the price, or lower the price. My company paid for several years' worth of Oracle Exadata licenses. You need to pay for the technical support and other features separately, on different contracts. In terms of affordability, my rating for Oracle Exadata is two out of five."
"I'm giving Oracle Exadata five out of ten in terms of pricing. Its price could be lower."
"The price of Oracle Exadata is expensive. It is not competitive with other solutions some of the times."
"It is quite expensive."
"We pay for an annual license and it is expensive."
"The pricing of Oracle Exadata is too high."
