Physical logging and simple large objects

The database server pages in the physical log can be any database server page, including simple large objects in table spaces (tblspaces). Even overhead pages (such as chunk free-list pages, blobspace free-map pages, and blobspace bitmap pages) are copied to the physical log before data on the page is modified and flushed to disk.

Blobspace blobpages are not logged in the physical log. For more information about blobspace logging, see Log blobspaces and simple large objects.
