First create the index UNUSABLE - which will create each index as a single extent at virtually no cost.

Then for rebuild each partition.

Than add the PK using the index.

(At least, that's what it says in my book ;) I think you'll find a similar piece of advice in the PL/SQL packages manual under the
PCXUTIL package.

>Hi List,
>We are using Oracle 8.1.7 (64 bits) with Solaris 8

>I have a big table with over 300 millions rows (10 Go),

>When we try to create a constraint primary key (with dedicated
tablespace),
>we fail each time because the database was unable to extend temp
segment.
>1/ Instead of enlarging the temp tablespace undefinatly , is it
possible to

amount

>2/ If not, creating an unique will also be efficient for join ?
