Time Out during Download of CSV file

Question

Hello everybody,
I need some hints regarding CSV Downloads.
In some cases I am getting just blank pages after starting a CSV Download.
It seems to be related to the a,ount of data.
At about 5000 rows the download works fine, but with about 10.000 rows I am getting blank page.
It does not matter wether the download is started from an interactive report vie the menue or from a static report via the link.
I know that the query is running at about 20 seconds for the 5.000 rows.
A look into the Enterprise Manager tells me that the following function is using nearly all the CPU time during this session.
declare
rc__ number;
simple_list__ owa_util.vc_arr;
complex_list__ owa_util.vc_arr;
begin
owa.init_cgi_env(:n__,:nm__,:v__);
htp.HTBUF_LEN := 63;
null;
null;
simple_list__(1) := 'sys.%';
simple_list__(2) := 'dbms\_%';
simple_list__(3) := 'utl\_%';
simple_list__(4) := 'owa\_%';
simple_list__(5) := 'owa.%';
simple_list__(6) := 'htp.%';
simple_list__(7) := 'htf.%';
if ((owa_match.match_pattern('f', simple_list__, complex_list__, true))) then
rc__ := 2;
else
null;
null;
f(p=>:p);
if (wpg_docload.is_file_download) then
rc__ := 1;
wpg_docload.get_download_file(:doc_info);
null;
null;
null;
commit;
else
rc__ := 0;
null;
null;
null;
commit;
owa.get_page(:data__,:ndata__);
end if;
end if;
:rc__ := rc__;
end;
My ApEx-Version is 3.1.2.
Anybody any idea what might cause this problem?
Regards, Tine.

Hi,
if your APEX applications are accessed from Oracle HTTP Server (OHS) you can increase the 'TimeOut' directive in the OHS configuration.
The default value for this directive is 300 seconds.
