How To Create a New Tablespace
How To Create a New Tablespace? - Oracle DBA FAQ - Managing Oracle Tablespaces and Data Files
✍: FYIcenter.com
If you want a new dataspace, you can use the CREATE TABLESPACE ... DATAFILE statement as shown in the following script:
SQL> CREATE TABLESPACE my_space 2 DATAFILE '/temp/my_space.dbf' SIZE 10M; Tablespace created. SQL> SELECT TABLESPACE_NAME, STATUS, CONTENTS 2 FROM USER_TABLESPACES; TABLESPACE_NAME STATUS CONTENTS ---------------- --------------- --------- SYSTEM ONLINE PERMANENT UNDO ONLINE UNDO SYSAUX ONLINE PERMANENT TEMP ONLINE TEMPORARY USERS ONLINE PERMANENT MY_SPACE ONLINE PERMANENT SQL> SELECT TABLESPACE_NAME, FILE_NAME, BYTES 2 FROM DBA_DATA_FILES; TABLESPACE_NAME FILE_NAME BYTES --------------- -------------------------------- --------- USERS \ORACLEXE\ORADATA\XE\USERS.DBF 104857600 SYSAUX \ORACLEXE\ORADATA\XE\SYSAUX.DBF 461373440 UNDO \ORACLEXE\ORADATA\XE\UNDO.DBF 94371840 SYSTEM \ORACLEXE\ORADATA\XE\SYSTEM.DBF 356515840 MY_SPACE \TEMP\MY_SPACE.DBF 10485760
So one statement created two structures: a tablespace and a data file. If you check your file system with Windows file explorer, you will see the data file is located in the \temp directory of. The data file size is about 10MB. Its contents should be blank and full of \x00 at this time.
