11g Release 2 (11.2)
Part Number E17120-05
Beginning with Oracle Database 11g release 2 (184.108.40.206), the
DBMS_SPACE_ADMIN package includes the
DROP_EMPTY_SEGMENTS procedure, which enables you to drop segments for empty tables and partitions that have been migrated from previous releases. This includes segments of dependent objects of the table, such as index segments, where possible.
The following example drops empty segments from every table in the database.
BEGIN DBMS_SPACE_ADMIN.DROP_EMPTY_SEGMENTS(); END;
The following drops empty segments from the
HR.EMPLOYEES table, including dependent objects.
BEGIN DBMS_SPACE_ADMIN.DROP_EMPTY_SEGMENTS( schema_name => 'HR', table_name => 'EMPLOYEES'); END;
This procedure requires 11.2 compatibility level.
