Disk, memory, and process management
Shared memoryThese topics describe the content of database server shared memory, the factors that determine the sizes of shared-memory areas, and how data moves into and out of shared memory.
Virtual portion of shared memoryThe virtual portion of shared memory is expandable by the database server and can be paged out to disk by the operating system.
Components of the virtual portion of shared memoryThe virtual portion of shared memory stores a variety of data.
Shared-memory internal tablesThe database server shared memory contains seven internal tables that track shared-memory resources.

Tblspace table

he tblspace table tracks all active tblspaces in a database server instance.

TAn active tblspace is one that is currently in use by a database session. Each active table accounts for one entry in the tblspace table. Active tblspaces include database tables, temporary tables, and internal control tables, such as system catalog tables. Each tblspace table entry includes header information about the tblspace, the tblspace name, and pointers to the tblspace tblspace in dbspaces on disk. (The shared-memory active tblspace table is different from the tblspace tblspace.) For information about monitoring tblspaces, see Monitor tblspaces and extents.

The database server manages one tblspace table for each dbspace.
