Very scalable with high availability and excellent technical support
The good thing is that there are improvements coming with later function levels for the z/OS Db2. I'd like it if, with the operating system that we've got, z/OS, on the mainframe, it would allow us to refresh the hardware to run Linux dockers on the mainframe. This means this might give us opportunities for different ways of coming into the Db2 environment in the future. We just want a bit more integration with Linux. That said, we are already seeing Linux more readily available on the mainframe environment. Not only have we got the premium operating systems on OS. We can run LPARs on the same mainframe footprint that is also supporting Linux. This is what has improved and made the mainframe environment more competitive. We're also looking at AI for Db2 as well, and machine learning for the future. We know that AI has come out, that we're going to get that, and we're going to evaluate that product next year for Db2. That said, I haven't got any real complaints about Db2 on the mainframe. For the most part, a lot of the problems we have nowadays are to do with communication between the various teams that you would class as stakeholders.

Good storage and reliable but needs a better dashboard
I use Oracle Database just for storage of the corporate database data and the finance data I use Oracle Database just for storage of the corporate database data and the finance data. However, I find the dashboard to be complicated and not user-friendly. The dashboard is not user-friendly, and I…

Quotes from Members

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

Pros

"The valuable features include access path optimization, excellent performance, a robust locking mechanism, parallelism, and effective buffering in memory."
"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."
"When you submit a ticket the response time is quick."
"The solution's security is very tough and impenetrable."
"Very good for performance and scalability."
"The most valuable features of this solution are security and stability."
"The most valuable feature of this solution is the integration with other IBM products."
"I believe that because the support is good, they jump in and assist us in determining the root cause."
"The tool is efficient and fast compared to other alternatives. The tool's processing speed is fast, and we've experienced minimal hang-ups. This enables us to address queries within a shorter time frame. I wouldn't say it's just one particular feature, but overall, the efficiency and speed of Oracle Database have had a significant impact. Our support systems are more efficient, allowing us to accomplish tasks quickly."
"The performance of the solution is impeccable."
"What I like most is the real application security."
"Oracle Database has many useful functions and features suitable for big programs and complex business models."
"The interface of Oracle Database is very workable and easy to use."
"The command interface is very user-friendly. The required commands are not complicated and we are able to easily access the root system."
"Oracle Database is easy to install and set up."
"Oracle is somewhat user-friendly, and most customization or integration with Oracle-related projects is simple."
 

Cons

"Its process of building up queries could be more accessible."
"IBM Db2 Database is not ACID compliant, which would improve it. Db2 lacks Isolation, so when two people are trying to update the same field at the same time it can become stuck. Other newer databases do not have this issue, such as Microsoft SQL, Oracle DB, PostgreSQL, and SAP HANA."
"The solution could be more modern and have updated database technology."
"They should develop its containerized version."
"The queries can be difficult for beginners because there are so many. I would like to see more use cases for flow analysis that enable us to correlate the flow with events. Adding this feature in a QI format would be good for beginners."
"There could be better integration with some cloud solutions."
"I would like to see some artificial intelligence brought into the solution."
"There are some issues with Db2's database file system not being readable. The storage could also be increased, and the monitoring could be improved."
"They can simplify and make the deployment more user-friendly. Deploying Oracle solutions requires a lot of technical input. If that can be improved, it would really add value to the business."
"Improvements in Oracle Database could focus on simplifying deployment processes and providing clearer documentation."
"The adaptability to various APIs is something that needs to be improved."
"Frankly speaking, Oracle Database is very expensive."
"With the new version, we never came across any important limitations. There was nothing that needed improvement. However, in versions 9 and 10, we sometimes had problems, and big and complicated queries did not get through. In versions 11 and 12, I did not experience any problem. There could be some more information about load balancing and all these things. For me, it was just a part of the infrastructure maintained by other people. So, I cannot really say what they need."
"The previous version was a little clunky."
"Oracle Database could improve by providing access and integration with containers."
"The solution’s integration could be improved."
 

Pricing and Cost Advice

"It is expensive."
"Compared to Oracle, it is so much cheaper."
"If I consider the price of IBM Db2 Database, I would say there are cheaper products in the market."
"The solution's hardware and subscription model for support are very expensive."
"It is expensive. The price depends on the size of the machine on which you are installing the Db2 and the features you are using. It also depends on the country. IBM has different policies and different options for payment for this product."
"I rate the price of the IBM Db2 Database an eight out of ten."
"It's very expensive for West African countries like ours."
"Among Microsoft SQL Server, Oracle, and Db2, Microsoft SQL Server is the cheapest one, and Oracle is the most expensive one. Db2 is in the middle. As compared to SQL Server, its price could go down. It will be good for customers."
"The pricing is something that Oracle should work on to make the product more affordable, especially to businesses in third-world countries."
"We have bought a license, and it was a one-time cost."
"I rate Oracle Database's pricing a four out of ten."
"It could be cheaper. We pay for the license on a yearly basis."
"​The license cost need to be optimized. The licensing cost is very high compared to other RDBMS."
"The solution is expensive."
"I am using the trial version."
"You buy it when you need it, and then you pay the maintenance. We bought the licenses over 10 years ago. We haven't changed our licenses. We are not buying new licenses, and we are not looking at other devices. So, it is difficult to say whether it is cheap or expensive. There is nothing to compare to."
