I have once again proposed a session at VMworld 2012. This session is titled as follows:
Near Zero Downtime Migration of Oracle Database from Legacy RISC-based UNIX to x86-64 / Linux on VMware vSphere
The reason I believe this session is so important is simple: Every Oracle customer and his dog is desperately trying to get off of expensive, slow, proprietary RISC-based UNIX and onto the x86 environment. The reason for this desperation is simple: Cost. These environments are becoming hideously expensive platforms on which to run Oracle. Huge core counts. And performance is frequently terrible.
For example, EMC IT just replatformed off of their E25K and onto x86 / VBLOCK, in the process improving performance by 2 - 10 X and saving over $7 million per year. Yeah, that's real money.
