<div dir="ltr">Dan,<br><br>I shamelessly use techniques that I learn from reading the code for ejabberd. Even if to some learned Erlangistas it may not be the <i>ne plus ultra</i> of Erlang code, to me it's got a lot of things in it to which I say, "I didn't know you could do <i>that</i>!". Sometimes I struggle to figure out how to do something, being fairly new to Erlang/OTP myself, and I ask, WWJD (What Would Jabber Do?) and more often than not, there is an answer. You could do a lot worse than taking a look at its organization and techniques. It helps that it's a stable, real-world application that's in widespread production.<br>
<br><a href="http://www.ejabberd.im/">http://www.ejabberd.im/</a><br><br>Of course, ejabberd is not the only interesting Erlang application out there from which to cherry-pick idioms and techniques, it's just the first one I really looked into deeply. There are many others that are well done or cleverly done (and sometimes both), like RabbitMQ.<br>
<br>Hope this helps.<br><br>Regards,<br>Edwin Fine<br><br><div class="gmail_quote">On Wed, Sep 24, 2008 at 10:56 AM, <span dir="ltr"><<a href="mailto:Dana.RUBINO@rbs.com">Dana.RUBINO@rbs.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Hi Mazen,<br>
<br>
Can you be more specific please? I have had a look at the OTP Design principles i.e. release handling as suggested.<br>
<br>
Although it mentions target systems and building a release (.rel which looks good) it doesn't specify how I might specify the working Mnesia instance which I also want starting?<br>
<br>
Any ideas?<br>
<br>
Thanks,<br>
Dan<br>

<br>
Use targets systems that conform to OTP release handling and and this sort of things come to you for free... you don't need to start Mnesia from your application.<br>
