Ken,

Why not generate the alter index {} rebuild tablespace {} commands using sql,
break the resulting commands up into several different files, and run them at the same time?

Probably the easiest (and fastest) way to go.

The generate script would be:

set head off
set pages 1000
spool move_indexes.sql
select 'alter index ' || index_name || ' rebuild tablespace {new_tablespace_name};'
from user_indexes
spool off

Take the move_indexes.sql script, and break it up into, say 5 files and run 5 sql sessions at once.

Hope this helps.

I have this large DB (approx. 250 tables) that has the tables and indexes in the same tablespace (not my design). Is there a way I can move all of the indexes to a separate tablespace en-mass? I know I can move them one at a time with the alter index command, but that would be rather time consuming.

Thanks,
