Hi,
Oracle 9.2.0.5

Other than recreating the table and index, is there any other method to reduce number of extents and chanined rows.

TIA,
Rakesh

Only way to reduce chained rows is to either make your database blocks bigger, or reduce the size of the table (data stored per row).

To reduce the number of extents, you need to change the storage parameters - make NEXT bigger will stop it extending, but wont reduce the number of extents.

Personally, I would move the table to a locally managed tablespace with uniform extents (of suitable size), and forget all about it.
