Restore 11g rman cold backup on same server.

Question

Hi All,
I have a requirement , where we have to clone one development database's to other database's sitting on the same host.
I have taken the cold rman backup and copy it different database's local folder.
I changed the db_name in target pfile and did the nomount , but when I tries to restore the controlfile , it throws me below errors.
Just to add to to it, I was ale to restore the controlfile to the location specified in pfile.
now , when I tries to mount the database , it throws me following errors
Snippet from target database's
SQL> startup mount pfile=/db/epmtrain/oracle/11.1.0/dbs/initepmtrain.bkp
