Chapter 8. The future of DB2 for z/OS
DB2 for z/OS has a rich heritage of features that has expanded over the past 12
versions, as client requirements to satisfy new and more demanding workloads
have increased. IT environments are faced with globalization, regulatory
pressures, and on demand access to structured and unstructured data. Where
there is demand for a reliable, available, and scalable information server to meet
these requirements, DB2 for z/OS is found as a core part of the architecture.
Significant features have been added to make DB2 for z/OS more accessible and
manageable, positioning DB2 as
the data server for all of your enterprise
workloads.
The future for DB2 is bright. You can count on IBM being an innovative company,
one of the top companies in terms of patents in their portfolio. DB2 development
is advancing the engine to continue to deliver the features that clients need most.
You can count on DB2 for z/OS to run your new workloads and to grow with
existing workloads. New SQL capabilities will enable your future application
needs, package application requirements, and porting of your data to DB2 for
z/OS. Enhanced portability will enable you to gain higher levels of business
resiliency for existing applications. Innovative security enhancements will offer
flexibility in authorizations and role definitions.
In addition, industry surveys support DB2 for z/OS total cost of ownership (TCO)
advantages when the assessment criteria is responsibly complete. Cost
comparisons must include the higher utilization rates obtainable with zSeries and
lower administrative costs achieved with centralized systems. Through

188 The Business Value of DB2 UDB for z/OS
advancements in DB2’s autonomic capabilities, the DB2 for z/OS financial
advantage will continue to be compelling.
The long-term IBM vision for DB2 on zSeries is to continue to closely couple DB2
and the z/Architecture. IBM will package the database, operating system, and
hardware together and roll in a “DB2 on Demand” black box. This will allow you to
easily configure and manage this highly capable and powerful environment from
a browser, without needing knowledge of such things as TSO and VSAM.
The intention is to dramatically reduce people costs. IBM will do this by
eliminating the need for zSeries skills and reducing database administrator skills
to an absolute minimum and then use an open, Web interface. Less specialized
knowledge requirements imply lower people costs, with people as the principle
cost going forward since hardware and software are becoming commodities.
This chapter covers some of the future advances in new workloads, business
resiliency, DB2 for z/OS platform synergy, and TCO.
