Executing many mappings, when I want

Question

Hello,
I have created 25 mappings that work as I wanted.
I would like to create something that execute all the mappings in an order I would have defined, to execute them when I want, instead of execute them one by one in control center. I can't use oracle workflow to schedule them because I want to execute the mappings when it is necessary.
Can I do that with OWB or do I have to create PL/SQL proc separately ?
Can I do that with 'expert' tools ?
Has someone had to do such a thing ? I don't know the way to find informations of what I want to do.
Thanks,
Nico

Something vaguely like this should do it....
CREATE OR REPLACE FUNCTION send_summary_mail 
return number
IS
retval number := 0; --default success
mailhost  CONSTANT VARCHAR2(30) := 'smtp01.us.oracle.com';
crlf      CONSTANT VARCHAR2(2):= CHR(13) || CHR(10);
pSender    VARCHAR2 := 'your.email@address';
pRecipient VARCHAR2 := 'their.email@address';
pSubject   VARCHAR2 := 'Process REsults for: '||to_char(sysdate,'dd/mm/yyyy');
mesg      VARCHAR2(32767);
mail_conn utl_smtp.connection;
cursor getResults is

           from   all_Rt_audit_executions
           where  execution_name = 'YOUR_PROCESSFLOW_NAME'
           and    parent_execution_audit_id is null --get top-level row

BEGIN
   mail_conn := utl_smtp.open_connection(mailhost, 25);
   mesg := 'Date: ' ||TO_CHAR( SYSDATE, 'dd Mon yy hh24:mi:ss') || crlf ||
           'From: <'|| pSender ||'>' || crlf ||

   loop

                  rpad(to_char(rec.number_errors),10)||
                  rpad(to_char(rec.elapse_time),10)||crlf;
   end loop;
   utl_smtp.helo(mail_conn, mailhost);
   utl_smtp.mail(mail_conn, pSender);
   utl_smtp.rcpt(mail_conn, pRecipient);
   utl_smtp.data(mail_conn, mesg);
   utl_smtp.quit(mail_conn);
   return retval;
EXCEPTION
  WHEN OTHERS THEN
    return 1;
END;I haven't tested this - heck I haven't even compiled it - and you will need to replace various variables, but the code is made up of bits and pieces from things that I know work.
Then you just add it to your process flow as a transformation activity at the end of the run.
