3) Registered the MYDB1 in RMAN Db.
4)Created a Pfile from MYDB1 database and changed db value and other values of MYDB1 to MYDB2(Database name to be duplicate)
5)Created a password file
6)Startup MYDB2 in NOMOUNT stage.
7) At RMAN prompt I have done below things to but i have getting the error

WARNING: DB_FILE_NAME_CONVERT resulted in invalid ASM names; names changed to diskgroup only.
You must check DB_FILE_NAME_CONVERT parameter on MYDB2 database
or I think you must add DB_FILE_NAME_CONVERT, LOG_FILE_NAME_CONVERT to DUPLICATE Command.
DUPLICATE TARGET DATABASE TO MYDB2
SPFILE
SET
  "DB_FILE_NAME_CONVERT"="+DATA/MYDB1/","+DATA/MYDB2"
