Answer Posted / shashisy

A temporary tablespace is mainly required for the
intermediate storage of temporary data during certain
database actions, for example:

Sorting/aggregation with CREATE INDEX, SELECT ...
DISTINCT, ORDER BY, GROUP BY, UNION, INTERSECT, MINUS (when
the memory area defined using SORT_AREA_SIZE is insufficient)

If data files are deleted it throws following err

ORA-01652: unable to extend temp segmen
