A new internal thread type, GatherWrite, is used by the Ingres buffer manager during operations that require the flushing of multiple buffers from the cache such as write behind, consistency points, and table purges. This feature is only available on platforms that offer writev() support. Consult the appropriate Readme file to determine whether this feature is supported on your platform.

This feature is enabled on a per-server basis using the gather_write parameter in Configuration-By-Forms. The default setting is ON.
