yes then we need to create a tablespace with larger size.
for this use: (if ur old temporay tablespace was locally managed tablespace) then follow

1. create temporary tablespace temp01
tempfile 'c:\temo1.tmp' size 100m

The extent management clause is optional for temporary tablespaces because all temporary tablespaces are created with locally managed extents of a uniform size

2. alter database default temporary tablespace temp01

3. Make old temporary tablespace offline or u can delete it.
