Hi : I am creating a unique index on 65 million rows for a table that is about 3GB. I have allocated about 3.5GB for the index creation. How can I monitor this while this index creation is happening, since when I coming closer to end of datafile or extents, I can add more space..
I tried dba_extents and dba_free_space for this index tablespace and this TS is going to hold only this index..

Thanks, ST2000
