I have followed below steps:
ALTER DATABASE BHACKUP CONTROLFILE TO TRACE;
Then go to UDUMP destination pick it up and modify the value of MAXDATAFILES
sql> @(name of edited file);
Create soft link for the rest location in the location we providing in the clause 'BACKUP LOCATION'.
Please perform the following steps, as shown here.
1. Create the softlink on all of the individual RMAN backuppieces required for the RMAN duplicate, as shown in the example here. You may change the '/tmp/rmanbkup' on a different directory where you want to create those softlinks.
ln –s /u02/oracle/level0_backup_21042018 /tmp/rmanbkup/bkp3
ln –s /u03/backup /tmp/rmanbkup/bkp1
ln –s /u04/backup /tmp/rmanbkup/bkp2
Now use /tmp/rmanbkup/ as your backup location in your restore script.
RMAN> catalog start with '/tmp/rmanbkup';
