Rman 11g release 2 provides us the flexibility of creating the rman duplicate without connecting to the target database and recovery catalog.
All rman needs here is the location of the backup pieces which is accessible and rman reads the backup pieces and restores the spfile,controlfile,datafiles and archivelog files to perform the duplicate operation.
An example for this kind of duplicate operation is:
RMAN> DUPLICATE DATABASE TO <auxiliary DB name>
UNTIL TIME "TO_DATE('29-MAY-2010 14:16:42','DD-MON-YYYYHH24:MI:SS')"
set control_files='D:\<aux path>\c1.ctl'
set db_file_name_convert='D:<target path>','D:<aux path>'
set log_file_name_convert='D:<target path>','D:<aux path>'
BACKUP LOCATION 'D:\<location of backup on disk>';
# Here use of the BACKUP LOCATION clause identifies the type of duplication as having no target connection, no recovery catalog and being backup-based.
