TEMPFILE '/oradata/mytemp_01.tmp' SIZE 20MĮXTENT MANAGEMENT LOCAL UNIFORM SIZE 16M How does one create Temporary Tablespaces? Use V$TEMPFILE and DBA_TEMP_FILES instead. Unlike datafiles, tempfiles are not listed in V$DATAFILE and DBA_DATA_FILES. SQL> ALTER TABLESPACE temp ADD TEMPFILE '/oradata/temp03.dbf' SIZE 100M Use the following statement to add a TEMPFILE to a temporary tablespace: If you remove all tempfiles from a temporary tablespace, you may encounter error: ORA-25153: Temporary Tablespace is Empty. SQL> ALTER DATABASE TEMPFILE '/oradata/temp02.dbf' DROP INCLUDING DATAFILES However, one can remove a TEMPFILE from a database. One cannot remove datafiles from a tablespace until you drop the entire tablespace. This is why it is much quicker to create a TEMPFILE than to create a normal database file. When you create a TEMPFILE, Oracle only writes to the header and last block of the file. Unlike normal data files, TEMPFILEs are not fully initialised (sparse).

It is essential to do a full backup of the database before using the ALTER DATABASE CHARACTER SET statement, since the command cannot be rolled.ĪLTER DATABASE NATIONAL CHARACTER SET ĪLTER DATABASE CHARACTER SET WE8ISO8859P1 īut before changing the character set, its reccomended to use the Character Set Scanner utility. To ensure data integrity, whenever migrating to a new character set that is not a strict superset, you must use export/import. WARNING: Attempting to change the database character set to a character set that is not a strict superset can result in data loss and data corruption. If, the new character set is a strict superset of the current character set, it is possible to use the ALTER DATABASE CHARACTER SET to expedite the change in the database character set.
