Release 10.1A: OpenEdge Deployment:
Startup Command and Parameter Reference

> ## Before-image Buffers (-bibufs)

> Use Before-image Buffers (`-bibufs`) to specify the number of before-image buffers. This parameter is useful only when running the Before-image Writer (BIW).

> Operating system and syntax | UNIX Windows | `-bibufs` `n`
> Use with | Maximum value | Minimum value | Single-user default | Multi-user default
> Database Server | – | 3 | – | 20

> ``n``

> The number of before-image buffers.

> The BIW continually writes the filled before-image buffers to disk, making the buffers available to other client and server processes. Without a BIW writing the buffers, any gain from increasing the number of buffers is negligible.

> For more information on setting this parameter, see OpenEdge Data Management: Database Administration .
