Sbpages
An sbpage is the type of page that the database server uses to store smart large objects within an sbspace. Unlike blobpages, sbpages are not configurable. An sbpage is the same size as the database server page, which is usually 2 KB on UNIX™ and 4 KB on Windows™.
Smart large objects cannot be stored in a dbspace or blobspace. For more information, see Sbspaces, and sbspace structure in the disk structures and storage chapter of the HCL OneDB™ Administrator's Reference.
The database server calculates the extent size for a smart large object from a set of heuristics, such as the number of bytes in a write operation. For more information, see Extent sizes for sbspaces.
