Structure of an Additional Dbspace Chunk

You can create a dbspace that contains more than one chunk. The initial chunk in a dbspace contains the tblspace tblspace for the dbspace. Additional chunks do not. When an additional chunk is first created, it contains the following structures:
  • Two reserved pages
  • The first chunk free-list page
  • Unused pages
Figure 1 illustrates the structure of all additional chunks in a dbspace. (The structure also applies to additional chunks in the root dbspace.)
