Q: replace some datafiles

we're running owg 7.1.6 (HP-UX 10.01, NOARCHIVELOG) with one instance with 4 database users. every user has it's own datafiles.

we're doing a cold backup of all files (datafiles & controlfiles etc.) every night. now i think of restoring data from one of the users.

is there a way to
- shutdown oracle

• replace some of the database files (the datafiles of one user) from tape
• (do something i dont't know yet)
• start oracle
• (do something i dont't know yet)
• start the instance, working with the old datafiles of one user and the current datafiles of the other users.

(without creating different instances or using exp for backup)

TIA Johann
