Linux only: Kernel asynchronous I/O (KAIO) is enabled by default. You can disable this by specifying that KAIOOFF=1 in the environment of the process that starts the server. On Linux, there is a system-wide limit of the maximum number of parallel KAIO requests.

The numbers in red (number of active objects) show whether Oracle makes asynchronous I/O calls. The output will look a little bit different in Red Hat Enterprise Linux 4 and 5. However, the numbers in red will show same behavior in Red Hat Enterprise Linux 3 and Red Hat Enterprise Linux 4 and 5.

Ensure that all Oracle Database files are located on file systems that support asynchronous I/O. Set the FILESYSTEMIO_OPTIONS initialization parameter in the parameter file to one of the following values: Linux Distribution ... the driver that you use must support vary I/O. On Linux on POWER, you can use direct I/O on Red Hat Linux 4.
