You do not restore INTO a database, you restore a database.
That is (simplifying) nothing of the database exists before you restored.

Explain your requirements.

Thanks Micheal.

My Requirement.

Say Database A-I Take a RMAN Cold Backup Today.The TAG Name is TAG28125

Now i want to use the same Cold Backup after 6 days and refresh another database B.

A has Datafiles mount points like /u01/oradata/A
B has datafile mount points like /u01/oradata/B

A and B are in the same Server.

Another way of putting it..

"Use the Cold BACKUP of database A taken 6 days backs and refresh Database B running in the same server and mount points like above"

You can't.
You can use this backup to create a new database.

Backup and Recovery Advanced User's Guide
Chapter 7 Advanced RMAN Recovery Techniques
Section Restore and Recovery of the Database on a New Host

It is the same thing on the same server, you just have to care that your instance name is B and not A.

Michel is asleep & won't be back online for at least 2 - 3 more hours.

>Do u mean to say I cannot use the Cold Backup of A and refresh B on the same machine
depends on what you have & what you desire.
If you restore when ORACLE_SID=B, you will eliminate & lose what ever was contained in database B prior to doing the restore.

You cannot "refresh" in the meaning insert data into an existent database.
You can "refresh" in the meaning replace the database by a new one from the backup.
Cold or hot is irrelevant to the question.
