No archiving, no backup, rm accidentally deleted all data files for recovery (4)

For how recovery works, see the first blog on the Restoration topic:
Http://fly1116.blog.51cto.com/8301004/1337681
For a brief introduction to the fly. sh script used in the restoration process and other scripts, see the second blog on the Restoration topic:

If the database is not in the archive State and there is no backup, you can use the operating system command rm to accidentally delete all data files. How can this problem be recovered?
1. The database version is 11.1.0.7.0 and the database is not archived.

SQL> select * from v$version;BANNER--------------------------------------------------------------------------------Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit ProductionPL/SQL Release 11.1.0.7.0 - ProductionCORE    11.1.0.7.0      ProductionTNS for Linux: Version 11.1.0.7.0 - ProductionNLSRTL Version 11.1.0.7.0 - ProductionSQL> archive log list;Database log mode              No Archive ModeAutomatic archival             DisabledArchive destination            /archivelogOldest online log sequence     45Current log sequence           47SQL>

2. Create a fly table under the fly user. The table record is: 2256800.

3. View and delete all data files

4. An error is reported when a fly user creates a table.
