TABLESPACE_BACKUP_MODE?

Question

Hi,
I am new oracle and doing some experiment with it.
I connect as sys and did as follows.
(oracle 10.1.0.2.0 and windows xp)
SQL> ALTER TABLESPACE EXAMPLE END BACKUP;
Tablespace altered.
SQL>
SQL> alter tablespace example begin backup;
Tablespace altered.
SQL> shutdown abort;
ORACLE instance shut down.
SQL>
SQL> startup;
ORACLE instance started.

Variable Size 145488364 bytes
Database Buffers 25165824 bytes
Redo Buffers 524288 bytes
Database mounted.
ORA-01113: file 5 needs media recovery
ORA-01110: data file 5: 'E:\ORACLE\PRODUCT\10.1.0\ORADATA\OCA10G\EXAMPLE01.DBF'
when the tablespace in backup mode I change the data in example tablespace .
Can I recover this issue?
Expecting your help.
Thanks,
Manoj.
