Structure of a Regular Dbspace
After disk-space initialization, you can add new dbspaces. When you create a dbspace, you assign at least one chunk (either raw or cooked disk space) to the dbspace. This chunk is referred to as the initial chunk of the dbspace. Figure 1 illustrates the structure of the initial chunk of a regular (nonroot) dbspace.
When the dbspace is first created, it contains the following structures:
- Two reserved pages
- The first chunk free-list page in the chunk
- The tblspace tblspace for this dbspace
- Unused pages Figure 1. Initial Chunk of Regular Dbspace
