ORA-01652: unable to extend temp segment by 128 in tablespace TEMP

Hi,
I am moving an index to another tablespace using
alter index <indexname> rebuild tablespace <new tablsepace>;

The index segment size is 5 GB and temp tablespace is 2 GB.

I am getting the error:
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP

Does it mean I need to increase my temp tablespace to at least  5 GB ?

TIA,
Rakesh

Rakesh,

i am sorry but it is not that simple. The Temp space required is the space required for Oracle to calclulate the index entries, not the space required to store the index itself.

That means that you could require an additional 100K or an additional 10Gb. My recommendation would be to Rebuild the TEMP tablepsace large with AUTOEXTEND on witht eh NEXT extent value being quite large, say 500K to allow for large operations.

After you perform large operations like this you can always resize the tablespace back down to your normal operational level.
