User Activity Auditing

Question

Hi
I want to audit User/session activity in my database...
I want the details like User Name/ Machine IP, Time logged in / logged out... and other details.
I know you can enable audit_trail and query the tables.. Is there anyway I can create a report / txt file else send a notification at the end of the day?
Require all the steps..
Thanks in Advance,
Radhika

Wow the code was great.... I was able to get the attachments... But I dont know how to specify a file which resides on the machine.. Can I give the path of the file where it is to be found and attach it....
Coz in
http://www.oracle.com/technology/sample_code/tech/pl_sql/htdocs/mailexample_sql.txt
There are examples of how to execute the package...
REM Send an email with 2 attachments.
DECLARE
conn utl_smtp.connection;
req utl_http.req;
resp utl_http.resp;
data RAW(200);
BEGIN
conn := demo_mail.begin_mail(
sender => 'Me <[email protected]>',
recipients => 'Someone <[email protected]>',
subject => 'Attachment Test',
mime_type => demo_mail.MULTIPART_MIME_TYPE);
demo_mail.attach_text(
conn => conn,
data => '<h1>Hi! This is a test.</h1>',
mime_type => 'text/html');
demo_mail.begin_attachment(
conn => conn,
mime_type => 'image/gif',
inline => TRUE,
filename => 'image.gif',
transfer_enc => 'base64');
-- In writing Base-64 encoded text following the MIME format below,
-- the MIME format requires that a long piece of data must be splitted
-- into multiple lines and each line of encoded data cannot exceed
-- 80 characters, including the new-line characters. Also, when
-- splitting the original data into pieces, the length of each chunk
-- of data before encoding must be a multiple of 3, except for the
-- last chunk. The constant demo_mail.MAX_BASE64_LINE_WIDTH
-- (76 / 4 * 3 = 57) is the maximum length (in bytes) of each chunk
-- of data before encoding.
req := utl_http.begin_request('http://www.some-company.com/image.gif');
resp := utl_http.get_response(req);
BEGIN
LOOP
utl_http.read_raw(resp, data, demo_mail.MAX_BASE64_LINE_WIDTH);
demo_mail.write_raw(
conn => conn,
message => utl_encode.base64_encode(data));
END LOOP;
EXCEPTION
WHEN utl_http.end_of_body THEN
utl_http.end_response(resp);
END;
demo_mail.end_attachment( conn => conn );
demo_mail.attach_text(
conn => conn,
data => '<h1>This is a HTML report.</h1>',
mime_type => 'text/html',
inline => FALSE,
filename => 'report.htm',
last => TRUE);
demo_mail.end_mail( conn => conn );
END;
Here where do I give the location of the file to be attached ? Cant I give the location? Then how else can i attach a file from an specified location?
Thanks
