delete from student_new;
FOR v_ins IN c_ins LOOP
INSERT INTO student_new values(v_ins.id,v_ins.first_name,v_ins.last_name,
v_ins.major, v_ins.current_credits);
end loop;
insert into log_table values(3,'error 3','ah ah ah...error occured');
dbms_output.put_line('success om jai sairam');
commit;
end;

Error:-

Enjoy coding

To use DBMS_OUTPUT:
Add -
SET SERVEROUT ON SIZE 1000000
at the top of the file

Before you call DBMS_OUTPUT.put_line() call
DBMS_OUTPUT.enable(1000000);

If I understand what you want ---
Your code is not even getting to the DBMS call. PLS 0553 means that (earlier, before you ran this code or as part of how you login) you changed NLS settings incorrectly.
This means your code is NOT even being run.
