Advanced features enhance business intelligence, but complex management calls for improved user guidance

While my experience with IBM Db2 Warehouse is somewhat limited, when compared to other databases such as Oracle, there are areas for improvement. They need to enhance the database to make it more user-friendly and easier to master. They should implement a more comprehensive graphical user interface with additional features. For instance, when users encounter problems, the system should provide better guidelines and troubleshooting directions, except for hardware-related issues. They need to implement tools that would help users perform basic troubleshooting rather than solely relying on support. Other databases have features where users can investigate specific issues using error codes. From my experience, many minor issues could be resolved before escalating to support.

Automated provisioning simplifies deployment and integration

The Oracle Database Appliance is customizable and has excellent features.I don't have any problems with Oracle Database Appliance because this product is very automated, with scheduler and automatic processes throughout. You can make small inferences and changes for creating all the specific modifications. The automated provisioning feature helps speed up the database deployment process because you can use one command or option to resize all the disks or increase memory, depending on the occasion. The Oracle Database Appliance has integration in OCI Cloud. The same services simplify all the manager work regarding backups, configuration, resizing disks, and other services. Deploying the Oracle Database Appliance both on-premises and in the cloud offers the same simplification. You simply input your database name and specify memory quantity, CPU quantity, and database size. The process is identical for both on-premises and cloud deployments. The flexibility of Oracle Database Appliance has helped grow business needs for many customers. Using the Oracle Database Appliance has positively impacted my organization because I can deliver it much more comfortably. Creating a database involves many processes, but with this solution, you just input the name and configure the network and other parameters. It is very similar to RDS in AWS services, where you specify the name, choose the engine, indicate parameter groups, VPC, subnet groups, and proceed. Both Oracle Database Appliance and RDS have greatly simplified the work.

Quotes from Members

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

Pros

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

"Some of the best features are stored procedures, parallelism, and different indexing strategies."

"It can scale effectively as long as resources are available."

"The solution is stable."

"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."

"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."

"IBM Db2 Warehouse is more resilient when dealing with business intelligence applications."

"Provides good security and reliability."

More IBM Db2 Warehouse pros

"The performance due to the all-flash of ODA is very nice."

"Oracle Database Appliance provides high stability."

"The solution is pretty automated, which takes out the possibility of human error."

"Oracle is a stable database."

"We value the appliance architecture with its “everything-in-a-box” highly standardized setup."

"Oracle has good technical support."

"The product is good value for money. It is a secure solution."

"The Oracle database is able to get the data, process it, and return it to the company's CEO's and CFO's within a single day, and thus they are able to find out yesterday's P and L by today. It has drastically reduced the amount and time of processing from seven days to one day."

More Oracle Database Appliance pros

Cons

"There should be more material available for training and training should be free."

"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."

"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 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."

"It takes a long time to have a new version or release, similar to Oracle."

"Lacks sufficient documentation and particularly in Spanish."

"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."

More IBM Db2 Warehouse cons

"It would be beneficial to have dedicated RAM included in the Oracle Database Appliance."

"The product's pricing is too high. We plan to migrate to another database in three to four years."

"The main thing would be to make ODA more affordable, to make it a more economical machine. Also, I would like to see virtualization, so you could implement all of your functions on one machine. Finally, improvement in the speed and performance would be good."

"I would rate the scalability a seven out of ten. It has some problems. Databases are huge. This leads to needing more and more RAM and capacity resources, making it hard to scale. Because of this, we use Exadata. That's definitely a point for improvement."

"The solution's initial setup is not easy."

"The product is quite complex to set up, initially. It would be ideal if it was simpler."

"Oracle's product support is an area of concern where improvements are required."

"In my opinion only one single command should be used for all ODA models, as it’s confusing."

More Oracle Database Appliance cons

Pricing and Cost Advice

"In a traditional on-prem database, in a data warehouse, the solution is probably on the expensive side."

"Get benefit from the capacity-on-demand features. License your cores according to your licenses."

"The solution may be expensive, but when we consider the problems it solves, the stability it provides, and the fact that we don't have to buy separate parts and assemble them into a system, it becomes more affordable."

"The price should be lower."

"The product is costly."

"You must pay for the license."

"Oracle Database Appliance is a very expensive solution. If you have opted for the on-premises licenses from Oracle, then you have to pay yearly. If you have opted for the cloud subscriptions offered by Oracle, then you can pay either monthly or yearly."

"Leverage the Pay-As-You-Grow licensing, and consider using the ODA X6-2 S/M/L models also for SE2/SE."

"Oracle’s pricing is ridiculously high."
