zPCR and SOFTCAP are IBM tools to help you understand for a given workload expectations for changing hardware and software. Have you tried those tools?
http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/PRS268 http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/PRS1381 If you are growing your mainframe workload and developing significant complex large applications which heavily utilize DB2 then upgrading to Version 8 brings useful new feature and function and most importantly additional scalability needed by many to support demands already here or arriving in the near future. IBM has provided a great deal of material Redbooks, Webcasts, production documentation on DB2. If you planned, and tested, and planned, and tested then DB2 V8 brought few surprises when it reached production and many benefits. We expanded our DB2 bufferpools by over 10x so far and as a result have reduced I/O rates. The best I/O is no I/O! Using things like fixed bufferpools helps offset the CPU increases as does constant tuning by the wizards of DBA. CTS 3.1 brought new capabilities and the cost was certainly justified if you use he new capabilities to provide easier development and deployment of SOAP applications. The idea that there is a simple, single "increase in consumption " for any release upgrade is not realistic but IBM does publish a lot of information you need to consume because YMMV. I don't know of any platform where new feature and function is not being added with some expectation that customers upgrade hardware every few years and are willing to do so in order to maintain currency and be able to leverage new capability. I don't have a good answer if you just want to "keep the lights on". Try running Windows Server 2003 on a box that was good enough for Windows NT or NetWare.... Point... Running z9's, DS8000's, DB2 V8, CTS 3.1, z/OS 1.7.1 installing 1.8 in March, planning for zIIP, no JAVA workloads. I am happy IBM is still pouring money into zSeries development when that stops the platform really is dead!
