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

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 .
