These are the parameters which optimize the performance of the system. Like the average time to read data from disks.

In your oracle init.ora profile parameter filesystem I/O should be set to setall.

aio, cio and direct io should be properly analyzed depending on the version of your aix machine to start with the installation

rbrw = release behind read and write

cio = concurrent IO

-> have a look at sapnotes 999.524, 948.294
