User-managed incomplete recovery in noarchivelog mode

Hi all,

I have two full sets of close database files backup. One on 28 June and another on 29 June.

Today, 30 June, I need to restore the whole database by using the backup files on 29 June.

But I found that one of the data files, user01.dbf, was corrupted.

Since the database is running in noarchivelog mode and the online redo log was overwritten, so I try

1. Copy all db files of 29 June to replace existing.
2. Copy the datafile, user01.dbf, of 28 June to replace the corrupted file.
3. startup mount
4. recover database until cancel (I enter CANCEL since there is no available redo log file.)
5. alter database open resetlogs

However I have error when open the database: ORA-01152: file 1 was not restored from a sufficiently old backup ORA-01110: data file 1: '/u01/oradata/system01.dbf"

The tables in USERS tablespace is NOT important, is there any way for me to open the database?

Thanks.
