sorry to learn that you've heard negative reports about our MVS product. The sources of these rumours are very hard to pin down and often relate to Oracle Version 5, our first MVS product. As with other platforms Oracle7 is highly optimised for MVS and we have plenty of MVS customers that can demonstrate that performance is not an issue.

We no longer use the tier system, but over the last 3 years every tape we've shipped on MVS has been within Tier I guidelines, not Tier II. This means that Oracle for MVS ships around the same time as other lead ports. For a leading-edge MVS product this is a significant achievement, as I'm sure you'd agree.

Oracle7 runs on OS/390 - it was certified by the time OS/390 R1 went G.A. We'll be certified on R2 when that goes G.A. The Oracle Web Server has been available on OS/390 for some time.

Not sure what you meant by 'Large database performance is a serious concern'. The MVS benchmark figures I've seen for decision support workloads on 7.3 suggest otherwise.

Please feel free to give me a ring, I'm more than happy to share that data with you. (+1) 415 506 2722 Received on Wed Jul 10 1996 - 00:00:00 CEST
