Startup Command and Parameter Reference

After-image Buffers (-aibufs)

Use After-image Buffers (-aibufs) to specify the number of after-image buffers.

Operating system and syntax	UNIX Windows	-aibufs n

Database Server	–	1	–	20

n

The number of after-image buffers to use.

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 Coporation recommends you set After-image Buffers (-aibufs) to the same value specified for the Before-image Buffers (-bibufs) parameter, or a minimum of 20.

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