No, the assumption I was making was that the actual DB/2 database engine remained on z/OS, mostly for the reasons you mention. The idea is to move as much of the logic processing the data stored in DB/2 to IFL-hosted Linux systems, where processor HW is 66% less expensive, and where the advanced data access tools and programming environments that are all the vogue (and all the average street programmer knows) are already available at the levels expected everywhere else. Data access from the applications moves to DB/2 Connect. Example: constructing a web services app on the Linux side is a snap with .NET and Mono -- up and ready in less than an hour, and the Windows weenies don't have to know it's not Windows running their stuff if they're not total morons about the way they write their .NET code. The same app would take several days to do on z/OS alone. Time-to-market makes the difference. If you operate from that assumption, then a lot of the cycles consumed by the applications move over to the IFLs, and you can (in many cases) maintain or shrink the size of the std engine partitions, which directly impacts the license cost of IBM and ISV software on the z/OS side. Smaller model => smaller license price == more money for other goodies. One case I'm familiar with converted 1 standard engine to an IFL, reduced the size of their production z/OS configuration by 1 engine, and banked $600,000 difference in licensing costs at the end of the exercise if you considered changes in CA and z/OS OS licensing, and DB/2 licenses, etc. We're not talking pocket change here. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
