Sr. System Architect at a tech services company with 1,001-5,000 employees
IBM is the king of servers (Infrastructure) , IBM DB2 the king of Database Servers
What is most valuable?
I have benefitted from many features including:
- Product is built on RDBMS principles and principles of Normalization. Have benefitted by the normalization capabilities built into the product;
- SQL Query capabilities, Tools such as SPUFI, QMF, BMC Catalog Manager,DB2 File-Aid make it easy to query the data,
- Programming capabilities (such as host variables, cursors ) provided by languages such as COBOL to invoke DB2 DML statements to query, modify the DB2 Tables;
- Ability of DB2 rows to be presented to CICS screens, Batch Jobs, Web Programs;
- Entire 4 GL Tools such as Cool:Gen, Advantage Gen Encyclopedias implemented as DB2 tables;
- Entire Advantage Gen / Cool:Gen / IEF components viz. programs, program components are modeled as DB2 tables. Thousands of programs, program components built, accessed by thousands of programmers are stored as DB2 table entries. These are easily queried, extracted, modified, loaded to other regions by customized programs. Entire models can be created by copying DB2 tables. These are done reliably, consistently, and scalability is provided. This speaks about the power and capability of DB2;
- Entire Cool:Gen components / DB2 entries can be queried by IBM Websphere with ODBC connection and the results can be web enabled. This means DB2 is programmable for the web as well;
- DB2 entries can be extracted, modified and loaded to other regions and datawarehouses. IBM DB2 Unload, Load Utilities, products such as IBM Optim, IBM Websphere Datastage, IBM Websphere all enhance the capabilities and features of IBM DB2.
How has it helped my organization?
The product has improved our organization in many ways. IBM DB2 has been used in many client projects. These projects are used for a number of years (more than 20-30). Entire Enterprise Applications in the IBM Mainframes have been built with the capability of IBM DB2. Many applications have thousands of DB2 tables and millions of rows. These are accessed for Batch Programming via COBOL, for online / CICS programming via COBOL. Some entries can be accessed by IBM Websphere for Web Programming. This has provided the organization the ability to implement millions of business functions through online / batch / web programs.
What needs improvement?
It should be easier for web enablement. It is currently easy, but the more web products use the tool, the better it is.
For how long have I used the solution?
I have been using IBM DB2 (Mainframe Version) for more than ten years.
What was my experience with deployment of the solution?
No. Occasional bind problems would occur, but were resolved through proper configuration management tools, such as ENDEAVOR or CHANGEMAN.
What do I think about the stability of the solution?
No
What do I think about the scalability of the solution?
No
How are customer service and technical support?
Customer Service: We didn't have to contact customer service. Our DBAs would contact customer service if and when needed. However, the near-100% availability of DB2 and Advantage Gen Encyclopedia that was housed in IBM DB2 speaks of the reliability of the product and its customer service.Technical Support: Very Good. When I contacted my DBAs, they were able to resolve the binding errors, authorizations etc. quickly and efficiently.
Which solution did I use previously and why did I switch?
We switched from VSAM to DB2. DB2 is much more sophisticated and advanced than VSAM and provides a number of features which make it easier to access the data and present it, as well as use it.
How was the initial setup?
It was straightforward and easy. Many of the utilities provided by the vendor functioned very well. We were able to upgrade the Gen Encyclopedia easily.
What about the implementation team?
Through an in-house expertise.
What was our ROI?
It is enormous. We were able to implement many business projects on an ongoing basis without any issues.
What's my experience with pricing, setup cost, and licensing?
I was not involved in the pricing negotiations. I would say it was cost effective based on the number of successful projects.
Which other solutions did I evaluate?
No, IBM DB2 has been used by the clients for a number of years; in some cases more than 20-30 years.
What other advice do I have?
I would say that IBM DB2 is one of the topmost Database products. It has very high availability and scalability just like the other products from IBM, such as IBM Websphere server, IBM Websphere MQ Server, and IBM Websphere Datastage. IBM is the king of servers and infrastructure. You will do well going with IBM products such as DB2, Websphere. I would say that these are very stable and scalable and available products and provide much needed reliability for businesses.

Enterprise Solutions Architect at a computer software company with 201-500 employees
Stability, scalability and security with high performance.
What is our primary use case?
Internet & Mobile banking database
E-Payroll & E-Statement solutions
Website database
What is most valuable?
A) The command set is almost the same in Windows and AIX operating systems, which greatly minimize the administration efforts to manage DB2 in both environments. Needless to say that working with the banking sector (which is my default playground) I need the ability to deal with many operating systems.
B) The ability to understand and interpret PL/SQL queries, with ease switching from Oracle to DB2.
C) Stability, scalability and security with high performance.
How has it helped my organization?
Our software products have to be PCI-DSS compliant, so encryption of customers' credit card numbers is a must-have feature. Using DB2 AWSE v11 enables us to do out-of-the-box encryption with ease.
What needs improvement?
Backing up databases from Windows and restoring them on AIX and vise-versa.
Support for migrating DB2 v9.7 to 11 in a single process with no intermediate versions jumping
For how long have I used the solution?
More than five years.
What do I think about the stability of the solution?
No.
What do I think about the scalability of the solution?
No.
How are customer service and technical support?
IBM Knowledge Base is more than enough, I never asked them for support.
Which solution did I use previously and why did I switch?
I used Oracle DB and am still using it with some of my customers, but Oracle administration is a nightmare compared to DB2.
How was the initial setup?
The initial setup is straightforward, but securing your environment is a bit more complex.
What's my experience with pricing, setup cost, and licensing?
Use DB2 Express for your development environment, but consider using Workgroup Server Edition if you need to federate two databases together or need to server a huge amount of data. If you plan to be PCI-DSS compliant, use AWSE.
Which other solutions did I evaluate?
MS SQL Server 2014 and Oracle 12g.
What other advice do I have?
I recommend it to medium-to-large enterprise applications

Self-maintaining and self-monitoring data management
Pros and Cons
- "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."
- "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."
What is our primary use case?
Db2 is mainly used for Core Banking Systems, credit card systems, and production systems for CBS collecting.
What is most valuable?
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.
What needs improvement?
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.
For how long have I used the solution?
I've been using IMB Db2 Database for nine years.
What do I think about the stability of the solution?
There were a few hiccups directly after installation, but Db2 has been very stable since then.
What do I think about the scalability of the solution?
Db2's scalability is very good, especially when used in the IBM power system.

Very stable and scalable but the pricing is not transparent
Pros and Cons
- "The solution is very stable, in both hardware and database."
- "End-to-end encryption specifically is something the solution needs to have in the next release."
What is our primary use case?
We primarily use the solution for different banking systems.
What is most valuable?
The solution is very stable, in both hardware and database.
What needs improvement?
IBM just came out with new hardware in September, so they are getting ready for the cloud. If they can push through with all those features they're talking about, I think they have a good product lined up. Right now, the solution needs to have end-to-end encryption, to be cloud-ready, to have native support for Linux, and built-in data scientist workbenches. These are promised to us in the new release, and I hope that happens.
End-to-end encryption specifically is something the solution needs to have in the next release.
For how long have I used the solution?
I've been using the solution since 1998.
What do I think about the stability of the solution?
The solution is very stable.
What do I think about the scalability of the solution?
The solution is very scalable. We don't plan on increasing usage any time soon, however.
How are customer service and technical support?
Technical support is good. they are pretty responsive.
Which solution did I use previously and why did I switch?
We also use SAP HANA. These are two different applications, however, and they have different use cases. HANA runs on memory. Db2 is a much more mature, older technology with its own platform. HANA is not that new but it's not that old either. It's much faster for sure. The difference is one is in-memory computing, while the other is a traditional database on hardware on the IBM platform.
How was the initial setup?
The setup is quite complex. The solution and the hardware build are two different events. The deployment itself doesn't take more than two weeks, followed by the setup which can take, depending on the organization and its processes, a few months to a year. It varies from client to client.
What about the implementation team?
IBM assisted us with the deployment.
They're quite good at what they do. They never deliver on time or on budget. However, they know what they're doing, as it's their product.
What's my experience with pricing, setup cost, and licensing?
The solution is pretty expensive and IBM isn't very transparent in their pricing plans. You need to be aware of what your company specifically needs before purchasing anything.
What other advice do I have?
I'd rate the solution a six out of ten.
