Michael, it's true that today DEC OSF/1 doesn't have clustering. Today. The engineering groups for DEC OSF/1 clusters and Oracle Parallel Server are working closely to deliver a set of quality products. DEC OSF/1 clusters use the memory channel technology from Encore Technology, and we anticipate leadership performance.

Performance of Oracle on OpenVMS is quite good. For Oracle Applications, it's within 10% of DEC OSF/1 performance. As for data recovery and failover technologies, OpenVMS has been delivering this for years. Also, since the users are already well-versed in OpenVMS, UNIX is a hard sell.

As for hard facts, I'll send you the industry-standard benchmark reports for DEC OSF/1 and OpenVMS on Alpha platforms. You'll be able to see how well the operating systems perform on artifical benchmarks.
