Use SQL*Plus to test a tablespace configuration with multiple datafiles 50 points Create a tablespace with one datafile. Use a uniform extent of 40 KB. Create three tables in this tablespace, and manually allocate 3 extents to each in turn (a total of 9 extents). Run a query against DBA_EXTENTS to find the physical location of each extent for each table. Add a second datafile to the tablespace. Manually allocate 2 more extents in turn to each table (a total of 6). Re-run the same query over DBA_EXTENTS. Manually allocate 3 more extents to first table, followed by 1 extent to the second table. Re-run the same query over DBA_EXTENTS. Tidy up by dropping the new tablespace with contents and datafiles. (1) Provide all interaction with the database, all the SQL queries (create, drop, select, etc.) and their corresponding results.
