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
Use with Maximum value Minimum value Single-user default Multi-user default
Database Server — 1 — 64
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, increasing the availability of empty buffers to client and server processes.

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

Note: Validations using -aibufs can be run online as part of routine health checks. For more information, see PROUTIL Utility in Manage the OpenEdge Database.
