ORA-01503: CREATE CONTROLFILE failed
ORA-01166: file number 601 is larger than MAXDATAFILES (600)
ORA-01110: data file 601: '/d10/oracle/mkkdbdata/hrx35.dbf'

Solution:

1. Correct s_dbfiles in source context file with your maximum number of database files. 
In order to find the maximum file id use:
select max(FILE_ID) from DBA_DATA_FILES;

2. Run autoconfig on DB tier on source in order to propagate the changes.

3. Redo all cloning steps.
