SQL & PL/SQL

Hello,

I'm using Oracle 11g, and have this code:

        ….

begin
    request_context := utl_http.create_request_context (
                wallet_path      => 'file:-------------------------------',
                wallet_password  => NULL
    );

    req := utl_http.begin_request(url => urlWhat, request_context => request_context);
    res := utl_http.get_response(req); 

    utl_http.read_text(res, resText);
    utl_http.end_response(res); 
   
    resXML:= XMLType.createXML(resText);

    doc                 := DBMS_XMLDOM.newDOMDocument(resXML);

...

exception

        when utl_http.end_of_body then

           utl_http.end_response(res);

        when utl_http.too_many_requests then

           utl_http.end_response(res);

….

The package works well, but after 5 requests I get the following error, even though I use utl_http.end_response:

ORA-29270: too many open HTTP requests

ORA-06512: ..., line 50

ORA-06512: ... line 1

29270. 00000 -  "too many open HTTP requests"

*Cause:    Too many HTTP requests were opened.

*Action:   End some HTTP requests and retry the HTTP request.

Can you help me? Whan I'm doing wrong?

Thanks in advance and best regards,

Alida
