AOLserver instances that are using the database that you wish to
drop. If you're using daemontools, this is simple, just use the
'down' flag (-d). If you're using inittab, you have to
comment out your server in <code class="computeroutput">/etc/inittab</code>, reread the inittab with
<code class="computeroutput">/sbin/init q</code>, and then
<code class="computeroutput">restart-aolserver <span class="replaceable"><span class="replaceable">$OPENACS_SERVICE_NAME</span></span>
</code>.</p><p>Then, to drop the db, just do:</p><pre class="programlisting">
[$OPENACS_SERVICE_NAME ~]$ <strong class="userinput"><code>dropdb <span class="replaceable"><span class="replaceable">$OPENACS_SERVICE_NAME</span></span>
</code></strong>
DROP DATABASE
