All of Oracle. Installation Guides. In version 10g, grid computing introduced shared resources where an instance can use CPU resources from another node in the grid.
Information is shared between nodes through the interconnect—the virtual private network. Storage[ edit ] The Oracle RDBMS stores data logically in the form of tablespaces and physically in the form of data files " datafiles ". Segments in turn comprise one or more extents.
Extents comprise groups of contiguous data blocks. Data blocks form the basic units of data storage. A DBA can impose maximum quotas on storage per user within each tablespace.
Specific partitions can then be added or dropped to help manage large data sets. Monitoring[ edit ] Oracle database management tracks its computer data storage with the help of information stored in the SYSTEM tablespace.
A data dictionary consists of a special collection of tables that contains information about all user- objects in the database. Since version 8i, the Oracle RDBMS also supports "locally managed" tablespaces that store space management information in bitmaps in their own headers rather than in the SYSTEM tablespace as happens with the default "dictionary-managed" tablespaces.
DBAs can manage these files manually or leave their administration to Oracle itself.
Note that a datafile has to belong to exactly one tablespace, whereas a tablespace can consist of multiple datafiles. Redo log files, recording all changes to the database — used to recover from an instance failure. Often, a database stores these files multiple times for extra security in case of disk failure.
Identical redo log files are associated in a "group". Government customers are "commercial computer software" or "commercial technical data" pursuant to the applicable Federal Acquisition Regulation and agency-specific supplemental regulations.
