Speeding up Oracle disk I/O on RHEL4 systems
While poking around the web last wek, I came across a good paper from Redhat that describes how to utilize asynchronous and direct I/O with Oracle. I have been using the Oracle filesystemio_options=”SetAll” initialization parameter on a few RHEL 4 database servers to efficiently use memory, and had no idea idea that it provided the throughput numbers listed in Figure 2. Nice!
