You need to have 15 to 20gig temp space to do this, assuming you are equipartitioning the primary key index.

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), We have partinionned this table by range of date. 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 create this constraint for each partition so that it would reduce the amount of temp segment required ?

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

Thanks in advance!
Philippe
