@niday, try online redo logs, if you are lucky this will work, if you are not, you just can offline drop the file and then the tablespace.
@Arju, if archived logs never existed then Oracle has redo records still in online redo logs, so apply step 4. If it existed and you lose it then you're in trouble.
Regards
Michel

How to know whether archivelod log exists or not?
I execute command "archive log list", and return :
SQL>archive log list;
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination /data/app/oracle/OraHome1/dbs/arch
Oldest online log sequence 5251
Current log sequence 5253
otherwise how to see online redo log ?
Thank you very much . I am a freshman, and so sorry.

Arju:
I think recover the initial wrong circumstance is better because wrong circumstance has been changed.
I recover the initial wrong circumstance with the oracle installation directory which is gave to me by customer ,
I do the startup , error exists :
