Mainframe Technical Manager/Service Integration Lead at Saudi Business Machines

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.

Ensures that users experience a good return on investment

Firstly, a user should prepare the operating system for installation, and then we have to copy the software to install the product. When dealing with scenarios related to Oracle Real Application Clusters, users need to add nodes and storage. The setup process is a little bit complex compared to DB2. The setup process of Oracle Database In-Memory takes around five to six hours to install Oracle Real Application Clusters, if everything is okay, apart from which the other processes will take a day. The solution is deployed on an on-premises model. The cloud-based solution is available for testing and development, and it need not be installed in your environment. A user just needs to do a few clicks and select the database, after which it automatically gets installed in the cloud. Only in the on-premises version of the product, there is a need to do some work in the tool.

Quotes from Members

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

Pros

"The solution has very good data compression of up to 50%. For example, if you have 50 terabytes of data, it can be reduced to 25 terabytes."

"The solution's security is very tough and impenetrable."

"It is quite a stable solution."

"Your iOS, your throughputs, your performance cycles, you cannot touch it with Microsoft or with Oracle scalability-wise. That is far and away the most scalable systems and the highest performing systems of the set of them."

"Very good for performance and scalability."

"The scalability and availability of this solution are the most valuable features."

"The solution is a very stable relational database and has integration with legacy systems. It is a great product."

"It's the best solution in terms of security, performance, and availability because the system is available 24/7."

More IBM Db2 Database pros

"The solution is very fast."

"The application development is very user-friendly."

"The product offers high scalability."

"We find the dashboard and the speed of data processing very valuable in Oracle Database In-Memory."

"The scalability is very good."

"I find the performance features of Oracle Database In-Memory to be most beneficial."

"The on-premise version is stable. We have different teams and resources for the server side, for admin, and for development. We can easily take care of all the services and applications."

"Normally, every database server uses hard disks. In-Memory has a feature, apart from their database, which is very good. When we start our server, all your data needs loading memory. We can use that. It's a very good feature. I think they added this feature in 2019. We can mount memory in the partition, create partitions in there, and create table space from that spot to share. It's a really good feature. We use it a lot."

Cons

"IBM's products tend to be quite costly, especially given the availability of free, open-source alternatives."

"Their view of it is they're maintaining it, they're continuing to upgrade it, they're continuing to grow it, however, they don't go out and try and sell that as an architectural solution the way they do Linux and Unix."

"The problem with this environment is that any software that you install is very costly because there are no free tools for this environment."

"They should develop its containerized version."

"There could be better integration with some cloud solutions."

"It would be helpful to have more querying tools and more development tools for us to work easily with Microsoft."

"I would like to see some artificial intelligence brought into the solution."

"When I look at Microsoft SQL Server, SQL Server provides me with better tools for database management."

More IBM Db2 Database cons

"The platform’s pricing needs improvement."

"Oracle Database In-Memory is more expensive than Azure, and the support from the Oracle team is not very good, especially since they do not have a support team in our region."

"Lacks sufficient integration with other tools."

"The solution should move to the new way of writing software code with AI that is intelligent and learns."

"They should improve the solution's scalability for large databases."

"The high cost of the product is an area of concern where improvements are required."

"Oracle Database In-Memory appliance-based solutions can be restrictive for some applications, as they may require more flexibility in the database design to be tuned and sized to the customer's needs."

"We often have to find solutions on our own through the support site, so there's room for improvement in this regard."

Pricing and Cost Advice

"We normally handle large size businesses and as far as I am aware, the license is negotiable based on the number of users and the quantitative data."

"It is expensive."

"The solution costs less than other products."

"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."

"We purchase the product's yearly license."

"It's very expensive."

"It's very expensive for West African countries like ours."

"We did not buy it. It came with our hardware without any complimentary maintenance. If I compare Db2 Database with Oracle Database, its price is lower than Oracle Database."

More IBM Db2 Database pricing and cost advice

"The product is expensive."

"It's quite costly and it comes with a fixed price."

"The pricing is pretty good so I rate it an eight out of ten."

"Oracle Database In-Memory is expensive."
