We performed a comparison between IBM Db2 Database and IBM Netezza Performance Server based on real PeerSpot user reviews.
Find out what your peers are saying about Microsoft, Oracle, SAP and others in Relational Databases Tools."I like that its true active-active. For example, if there are two instances within a cluster, we can take one of them down and there's no failover or switch over. There's no primary and secondary, it's true active-active. We can take one side down and we can upgrade that with new maintenance or a new version, obviously testing coexistence beforehand, without impacting the business."
"It has a good feature called pureScale, which is just for scalability. It is a perfect solution for environments where scalability is going to be an issue."
"Its functionality and availability are valuable. Its availability is great. It is available 99.99% of the time."
"The solution is easy to install and simple to maintain. The most valuable aspect of the solution is its general user-friendliness for users of all kinds."
"The solution is stable."
"When you submit a ticket the response time is quick."
"The most valuable features are with the industrial side."
"Db2's best features are that it's self-maintaining and self-monitoring, which means I have to view and monitor the database far less often."
"IBM Netezza Performance Server is a cost-effective solution."
"The most valuable features of the IBM Netezza Performance Server are the NPS server because of the reduced maintenance and overall good performance."
"Distribution concurrency control."
"The underlying hardware that IBM provides with this appliance is made for a specific purpose, to serve performance on a large amount of data, and to do analytics as well. It is faster, when you compare it to any other product."
"The most valuable feature would be the fact that it has been running for awhile in an appliance format."
"The data governance prospect... from what I've seen, that is a really powerful tool as well, to help with data lineage and keeping track of that."
"The benefit is really because of the additional speed that we have and, truth be told, the more updated ETL processes and the revamped scheduler in general."
"We are able to execute very complex queries. Over 90 percent of our query executions are one second or less. We do millions of queries everyday."
"Performance is something that can be improved with DB2."
"We need some time to improve the performance. We have to perform a weekly REORG, or else RUNSTATS for the databases."
"There could be more user-friendly tools with features such as drag-and-drop functionality, visual basics, and low-code capabilities."
"GUI needs improvement."
"It would be ideal if the solution offered backup functionality. Many similar tools already do, which means Db2 is somewhat behind the curve in terms of what a customer might expect from it."
"The solution could improve by providing more integration."
"The licensing fees can be reduced."
"The management of Db2 should be simplified because there are not too many specialists in this area, and the learning curve of Db2 specialists is very long. After the courses, probably it takes one and a half or two years to get to the point when you are using the product properly in the production systems. So, the complexity is very high, and the most important thing is to simplify the management of the product, including self-maintenance. They should simplify the installation, management, and monitoring to simplify the product. It takes too long for a person to be a specialist in this product."
"IBM Netezza Performance Server could improve its interface, support for big data, and APA-based connectivity should be available."
"Our main problem with it is concurrency. When there are too many users running Netezza at the same time, this is when we have the most complaints."
"LIke Teradata, we can’t add a node/SPU to the existing appliance."
"The only issue is that it's not expandable."
"The scalability is not as expected. The capacity in the black box is not enough."
"In terms of features that I would like to see, one is the ability to actually scale out an architecture. Right now, if you buy one, it's fixed. There is no scale-up availability at all."
"Oracle Exadata's security features, like TDE encryption, are missing in IBM Netezza Performance Server."
"We are not able to scale. The only way to scale is to get another appliance, but we have a customers who would need us to hydrate the data between the two appliances, and Netezza does not do that."
