After-image Buffers (-aibufs)
n
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. Progress Software recommends 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.
