Sorry,

I forgot: cursor-attributes like %rowcount are not available in FOR <record> IN <SELECT-Statement> loops;
use a counter inside the loop and use the mod-function against this counter:

either

declare

   v_count number := 0;
begin

   for v_c1 in (select * from table_source) loop

      insert into table_dest values (v_c1.column_name1, v_c1.column_name2,.....);

      v_count := v_count + 1;
      if mod(v_count,1000) = 0 then
         commit;
      end if;

   end loop;
   commit;
end;
