This release of DB2 10 for z/OS should make IT executives sit up and listen when their technical teams come to them with their upgrade justifications and this is why….
At the end of October 2010 IBM launched the latest version of it’s flagship database product – DB2 10 for z/OS. A lot of work went into publicising the launch, I was asked to present at the launch webcast which attracted over 1300 registrations!
Having been involved in the early beta testing and in my role working with large DB2 z/OS users I’ve been able to really get to grips with some of the new technical features. However, as innovative as these may be and no matter how excited techies get about DB2 10 the bottom line is…..well….what difference is it going to make to the bottom line?! The business benefits of DB2 10 are what really matter to IT executives.
Even in the most favourable economic climate, businesses need to control costs and increase efficiency in order to improve their bottom line. In today’s more challenging business environment this has become a key factor for the survival and success of enterprises of all sizes.
I’m pleased to report that DB2 10 delivers significant “out of the box” benefits that many customers will be able to exploit with little or no additional effort. These include the most aggressive performance and CPU improvements of any DB2 release in the last 20 years, scalability enhancements to support ever-increasing workloads and productivity improvements to allow DB2 developers and support staff to respond more rapidly to the demands of the business.
Collectively, these features deliver real and quantifiable business benefit and I believe that customers will be considering upgrading to DB2 10 much more quickly than they may have done for previous releases.
DB2 10 delivers a number of significant business benefits, many of which require little or no database, application or system changes. These can be summarised as follows:
- CPU Reductions – DB2 includes a raft of enhancements aimed at improving application performance and reducing CPU usage. Most customers can expect to see net CPU savings of 5-10% in their traditional DB2 workload when compared to DB2 9, without any application changes being required. Significant additional savings are possible for other specific workloads and with some application changes.
- Scalability Improvements – DB2 10 delivers a spectacular increase in the number of threads that can be supported by a single subsystem – most customers will be able to achieve 5-10 times the number of concurrent connections compared to DB2 9. This will allow many customers to reduce the number of DB2 members needed to support their workloads, resulting in net CPU and memory savings and improving application performance.
- Productivity Enhancements – New features such as temporal tables, automated statistics and improved dynamic schema change reduce the effort required by developers and support staff to deliver robust DB2 applications.
Without getting into technical detail, there is one new addition which is worth mentioning. This version of DB2 10 supports skip migration which means that those currently running DB2 V8 can migrate directly to version 10. Just to note, version 8 officially goes out of support on April 30th 2012 which gives version 8 users 9 months to justify, plan and implement their next migration so timescales are tight for those who are at the beginning of that process. Those running version 8 are likely to be missing out on some fairly significant business benefits that DB2 9 could provide including CPU reductions.
As with any migration project it’s worth making sure you get some good advice on the pros and cons and go in to the migration project with your eyes open. Don’t underestimate the effort involved in a skip migration, or the “culture shock” for developers and support staff asked to take on two releases worth of new function in a single, large, indigestible lump.
That being said, with most customers being on usage based pricing the lure of CPU reduction makes a migration to DB2 10 highly appealing. Those customers that do decide to make the leap directly from Version 8 to Version 10 may see even bigger potential savings, as they will benefit from the cumulative CPU reduction of both V9 and V10 in one hit.
