This video presents how you can view existing tablespaces, view their datafiles, as well as create and delete a tablespace.
- [Instructor] The physical manifestation…of the Oracle database storage system…for user data is data files.…All database data is stored inside data files.…However, when a user creates a table,…the users specify which table space…that table should be created in.…A table space is a collection…of data files used for storage.…Let's see the names of existing table spaces…we already have defined in our database.…In order to do that let's open a sqlplus prompt…from the sysdba user, and log on to our database.…
We can use the dba_tablespaces data dictionary view…to view information about existing table spaces.…Let's start off by describing the structure…of the dba_tablespaces view.…Remember, no need for a semicolon at the end…of this command, because the describe command is not…a sql statement, it's an internal command for sqlplus.…Once we know the structure of the dba_tablespaces…data dictionary view, we can view the names…of existing table spaces by writing…select tablespace_name from dba_tablespaces,…and we can see we have six table spaces…
