The following procedure assumes that you do not have more than one target database registered in the catalog with the same name. If multiple target databases are registered with the same name, then you must specify the DBID with the SET DBID command so that RMAN knows which control file to restore. The DBID is the unique numerical identifier for a database.


*****************
Database 10.1.0.2.0
Archivelog mode.
status open 
through rman took complete bkp with below cmd.

rman>run
{
allocate channel c1 type disk format 'c:\datapump\data\%u';
backup database;
backup current controlfile;
}
*****
after that i was delete all controlfile from original location.
*****************
and i was perform restore or recovery operation with recovery catalog.
