ORA-01017: invalid username/password

Hello All

I successfully cloned a 12cR1 (12.1.0.2) RAC (2-nodes) oracle home running on RHEL 6.3 using following procedure https://docs.oracle.com/database/121/RACAD/clonerac.htm#RACAD7333

And now I am in the process of duplicating a database. So I created a pfile with DB_NAME=TEST, set ORACLE_SID=TEST1, created password file and when I try to start the instance in nomount stage, I get this error, there is no sqlnet.ora file under $ORACLE_HOME/network/admin directory.

export ORACLE_SID=TEST1

sqlplus / as sysdba;
