Hi all,
I'm trying to restore an oracle schema on noarchivelog database.
I locate dbf file from backup media.
Do I need to shutdown the database before and use another control files ?
How do I proceed ?

thanks for help

you do not restore a single data file.

Tell us more about what you have & what happened?

In an Oracle database, a "schema" is the set of logical objects that are owned by a user. Are you using schema in this sense? Or are you using it in what I think is the SQL Server context, where a schema is a set of physical files?

Havong re-read, I think I understand: you want to "restore" one schema, ie, the user and all his objects?
You can't extract that from a datafile backup. I would think that your only option would be to restore the entire database to a new location, then export the schema and then import it into your live database.

How to restore the "entire database to a new location ?
It's noarchivelog and cold backup database.

That would depend on how you made the backup.
If with RMAN, follow the usual routine for duplicating a database to a new location, as described in the docs.
If it is a user managed backup, restore it to the new location; edit the parameter file so that the instance can find the controlfile; startup mount; rename all the datafiles so that the controlfile can find them; open resetlogs.
Easy.

you can recover a schema without a backup.
in your scenario only last export using exp command is valid or last cold backup

You cannot RECOVER from an export dump, you can just restore as it was at the time of this export.
In addition, OP did never say he has an export dump just a cold backup.
