Humm, Looks like someone did not plan accordingly. Easy to do, I've done that a couple of dozen times. Here is a quick rule of thumb that I use. It is NOT absolute but I've not had a problem with running out of space in TEMP. The sql is:

select round(sum(nvl(vsize(<column_name>),1))/1048576)*2 from dual;

Whatever it returns in mega-bytes is what you need in total for dedicated temp space.

You have to add another datafile to index tablespace and also increase the temp tablespace size.

Hi all,

I need to build an index on a table of 80 columns with 3 million rows. The index is on 8 columns.

I got ORA-01630: max # extents (n) reached in temp segment in tablespace ARBOR_INDEX, so I add more index files and enlarge extents, now I have 2 index files of 1G each, and tablespace storage is:

ALTER TABLESPACE ARBOR_INDEX
DEFAULT STORAGE (
INITIAL 514K
NEXT 514K
MAXEXTENTS 4080
);

And I still got ORA0-1630. Should I continue to increase index file size and extents or there is other way around? The datafile contains that table's tablespace is only 1G.

I didn't do exp, build index, imp since I believe for large amount of data, it's better to load the data first then build index.

Any idea? Thank you.

Leslie
