Time: 7:15 PM - 8:00 PM

Track: Track 1

Major database upgrades provide an opportunity to review and possibly refine existing database architecture. For example, the release of Oracle 11gR2 coincided with availability of faster, more scalable CPUs. Memory has become increasingly affordable during the lifetime of Oracle 12cR1. The next release is likely to be accompanied by significant changes in I/O as the industry shifts from spinning disks to SSD. This session takes a look at the ways in which Oracle uses I/O; discusses how to measure existing and to calculate future performance, and identifies areas where improvements may be achieved.
