Hear what our Customers are Saying about DB2 10 for z/OS


JN DATA

“DB2 10 came at a very good time for us, as it will allow us to better cope with the very large increase in volumes we’re about to experience - the increased concurrency during the DB2 catalog restructuring reduced the impact to our production workload compared to previous upgrades.”

The new temporal functionality in DB2 10 for z/OS will allow us to drastically simplify our date-related queries. In addition, we’ll be able to reduce our storage costs by using cheaper storage for inactive rows and reduce our processing cost by having DB2 handle data movement more efficiently than the custom code we’ve written to do the same work in the past

ITERGO

"With IBM QMF 10 here are many enhancements which will make life easier. The biggest improvement for us was the enhancement regarding SAVE DATA support. We force customers to run their CPU-intensive queries in batch and in prior releases they failed after running for hours just because the table already existed and there were minor differences in the column definition. With the new release these failures are reduced as a result this improves productivity, saves cost and improves customer satisfaction"

Walter Janissen - ITERGO Information Technologies GmbH


CESVE

“Not a big iron anymore, but an efficient, scalable, reliable, open and business-oriented platform, this is now the mainframe… and with DB2 10 and its new exciting features and functions doing more work with same resources achieving the same high availability. This is a goal that can be easily achieved by every company. DB2 10 reduces total cost of ownership but keeps intact the power for future business opportunities"

Massimo Scarpa - CESVE - Servizi Informatici Bancari S.p.A Consortile


"We feel that performance, scalability improvements and security enhancements will really benefit our business. We are particularly interested in the performance improvements due to the potential CPU reductions that we realised during our DB2 10 Beta testing. Our early testing has shown out-of-the-box processing cost reductions of between 5% - 10% and for some workloads as high as 30%. Potential cost savings of this magnitude cannot be ignored given today’s business climate.”

"We are really excited about the Plan Stability enhancements in DB2 10 - we have a sophisticated procedure to assure quality in access path - this means, all packages run with their optimal access path, to assure this, we have to look at each new statement and maybe at each new rebind - this can be a time-consuming partly manual process. Plan stability offers an opportunity to reduce the daily effort and to improve the DBA's productivity"

Morgan Stanley

“Based on the performance metrics from our controlled test environment, we see a significant amount of CPU and Elapsed time savings. This release has many features that will help bring down our operating costs. We look forward to implement DB2 10 in our environment early next year”

BMW

“We use very large buffer pools – some of them up to 3.2GB in size. We rely on efficient access to buffered data and any saving in the cost of accessing that data will be very beneficial.”

Philipp Nowak, BMW Group DB2 Product Manager

"We are really thrilled about “Temporal Data" feature – this feature has the potential to significantly reduce overheads. We have estimated that 80% of our existing temporal applications could have used “the DB2 10 temporal features” instead of application code - this feature will drastically save developer time, testing time – and even more importantly make applications easier to understand so improve business efficiency and effectiveness"

Frank Petersen - System Programmer


Postbank

“With the optimisations in DB2 10, we are hoping to see a significant CPU reduction for our main SAP workloads; perhaps enough to defer our annual hardware upgrade cycle”.

UniCredit Group

“As we operate in a multi-national environment, we have to expend a lot of effort to ensure that we adhere to strict local audit requirements. The new security and administrative authorities in DB2 10 will greatly reduce that effort, and allow us to work in new territories much more quickly than before”

Luca MUSSATO - UniCredit Global Information Services S.C.p.A


Postbank

"We are excited about the scalability enhancements in DB2 10 - in a failover situation we currently have to be very careful about the amount of work that gets directed to a given DB2 system. The increased scalability in DB2 10 will allow us to simplify our failover automation and remain confident that DB2 can handle the increased workload"

Guenter Schinkel - Postbank Systems AG


Banco do Brasil

“With the scalability improvements in DB2 10, we expect to be able to quickly reduce our production data sharing group from 20 members to 15”, said Paulo Sahadi, Senior Production Manager at Banco do Brasil. With DB2 10 able to handle 5-10 times as many threads as the previous version, the upgrade will immediately give the bank some much-needed room for future workload growth while simultaneously reducing their data sharing overhead. “We will also save some CPU and storage from removing the five DB2 systems, and we will have to spend a lot less time monitoring our virtual storage”, added Paulo.

BMW

“With our DB2 10 testing so far, we have had quite a few surprises but all of them have been good. Every single SQL statement we have tested has been better or the same as our current optimal paths – we have yet to see any significant access path regression. We had to spend a lot of time tuning SQL with DB2 9, but we expect that to disappear when we upgrade to DB2 10.”

Philipp Nowak, BMW DB2 Product Manager


Postbank

“We are also excited about the new audit capabilities introduced in DB2 10. Unlike more traditional environments where DBAs get to explicitly create new DB2 objects, SAP environments often have tables being created by the system itself as part of a SAP transport mechanism. This makes it difficult for us to quickly audit new tables, as we have to ALTER the tables to enable the audit attribute and sometimes we have to wait weeks or months for a change slot. The new audit capabilities in DB2 10 will allow tables to be audited as soon as they are created, which is an obvious benefit for the business and will reduce costs and simplify our processes”

Guenter Schinkel - Postbank Systems AG


BMW

"Over the past several months, BMW has tested the new version of DB2 10 for z/OS, focusing on specific features and comparing these directly to the same features in DB2 9 for z/OS. One of the IBM design goals expected a general improvement in massive parallel SQL-insert performance, where we achieved close to 40% CPU improvement and significant elapse time reduction in direct comparison to DB2 9 for z/OS. For all of our critical tested selects statements, the version 10 optimiser chose the optimal access path, sometimes even improving previous access path choices in version 9. Overall, we are very pleased with the added functionality and architectural enhancements, and are looking forward to this exciting release."

Philipp Nowak - BMW Group DB2 Product Manager

“I have over 17 years DB2 DBA experience on System z and over 10 years Oracle DBA experience. My experience includes database design and definition, performance tuning and systems programming. I am really excited about DB2 10 — besides the CPU savings and usual system performance and functionality improvements which just get better with each version, DB2 10 for z/OS delivers an excellent and far superior data server environment for applications portability and enablement.”

Manuel Gómez Burriel CECA (Confederación Española de Cajas de Ahorros)

24/7 availability in parallel with reducing our mainframe total cost of ownership are two of our top operating priorities. DB2 10 for z/OS (US) has numerous new features such as increasing the capacity of DB2 and more efficient data access that will assist us in achieving our goals.”
