ORA-29284: File read error

Question

Good morning,
Need to do two flat file on a 2000 lien.
1 - Read a file. csv
2 - Keep it plain, unformatted information from a table
These are the steps I performed to achieve the first goal ...
1 - READING TEST FILE
CREATE OR REPLACE DIRECTORY PUBLIC_ACCESS AS 'C:\REPORTES_REY';
GRANT READ, WRITE ON DIRECTORY PUBLIC_ACCESS TO PUBLIC;
-- THIS PL / SQL works ok..
DECLARE
v1 utl_file.file_type;
v2 varchar2(600);
begin
v1:= utl_file.fopen('PUBLIC_ACCESS','prueba20110218.csv','R'); -- WORKS WELL ...
--v1:= utl_file.fopen('PUBLIC_ACCESS','sui_facturacion_alcantarillado_15085_2011_01_76845_001.csv','R');
loop
     begin
          utl_file.get_line(v1,v2);
          dbms_output.put_line('el contenido del archivo es: '||v2);
          exception
          when no_data_found then
          exit;
     end;
          dbms_output.put_line(' - ');  JUMP LINE
end loop;
     utl_file.fclose(v1);
exception
     when others then
     dbms_output.put_line(sqlerrm);
end;
but when you change the file name by map prueba20110218.csv de-> sui_facturacion_alcantarillado_15085_2011_01_76845_001.csv displays the following error
ORA-29284: File read error+
- this error to be?
I am grateful for the attention and cooperation extended ...
good day ...

Answer 1

Thank you very much for your cooperation extended
The file if it exists, the operating system is Windows, I'm running for the line of command and the file is in the same direction as the file prueba20110218.csv
Segi therefore his advice and remove:
exception
when others then
dbms_output.put_line(sqlerrm);
then run the following code:
DECLARE
v1 utl_file.file_type;
v2 varchar2(800);
begin
v1:= utl_file.fopen('PUBLIC_ACCESS','prueba20110218.csv','R'); FUNCIONA BIEN...+
v1:= utl_file.fopen('PUBLIC_ACCESS','sui_facturacion_alcantarillado_15085_2011_01_76845_001.csv','R',32767);
loop
begin
utl_file.get_line(v1,v2);
dbms_output.put_line('el contenido del archivo es: '||v2);
exception
when no_data_found then
exit;
end;
dbms_output.put_line(' - ');  SALTO DE LINEA+
end loop;
utl_file.fclose(v1);
exception
when others then
dbms_output.put_line(sqlerrm);
end;
+/+
ORA-06502: PL / SQL: error: character string buffer too small numeric or value
