Semantics

flashback_archive

Specify the name of an existing flashback data archive.

SET DEFAULT

Use this clause to designate this flashback data archive as the default flashback data archive for the system. When a CREATE TABLE or ALTER TABLE statement specifies the flashback_archive_clause without specifying a flashback data archive name, the database uses the default flashback data archive to store data from that table.

This statement overrides any previous designation of a different flashback data archive as the default.

See Also:

The CREATE TABLE flashback_archive_clause for more information

ADD TABLESPACE

Use this clause to add a tablespace to the flashback data archive. You can use the flashback_archive_quota clause to specify the amount of space that can be used by the flashback data archive in the new tablespace. If you omit that clause, then the flashback data archive has unlimited space in the newly added tablespace.

MODIFY TABLESPACE

Use this clause to change the tablespace quota of a tablespace already used by the flashback data archive.

REMOVE TABLESPACE

Use this clause to remove a tablespace from use by the flashback data archive. You cannot remove the last remaining tablespace used by the flashback data archive.

MODIFY RETENTION

Use this clause to change the retention period of the flashback data archive.

PURGE

Use this clause to purge data from the flashback data archive.
