Temp data file

Question

hello
As read somewhere that if we delete temp data file in oracle 10g, on restarting the database it automatically creates the new temp file. So deleted that file from oradata folder. Restarted the database but not creating new temp file.
can anyone tell why this is so?

Answer 1

But for XE it works:
SQL> select name from v$tempfile;
NAME
C:\ORACLEXE\ORADATA\XE\TEMP.DBF
SQL> shutdown abort
Instance ORACLE arrÛtÚe.
SQL> exit
