V$KERNEL_IO_OUTLIER contains entries corresponding to I/Os that have taken a long time (more than 500 ms) to complete. Use this view to see the individual kernel components of I/Os for which there are any occasional delays in serving disk I/O requests by the storage subsystem.
Although this view exists on all platforms in Oracle Database 12c, it is only populated on the Solaris platform.
