> The number of after-image buffers.

> Use After-image buffer (-`aibufs`) to specify the number of after-image buffers. This parameter is useful only when running the after-image writer (AIW) because the AIW writes the filled after-image buffers to disk, making the buffers available to other client and server processes. Try setting -`aibufs` to a value of 1.5 times the value of the Before-image Buffers (-`bibufs`) parameter, or a minimum of 5.

> Without the AIW writing the buffers, any gain from increasing the number of buffers is negligible.
