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).

Note: OpenEdge RDBMS internal validations used to ensure database consistency in both index and data blocks during forward processing, including -bibufs. Validations using PROUTIL can be run online as part of routine health checks. For more information, see Manage the OpenEdge Database.

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.
