<p class="MsoNormal">Hi folks,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m using OpenSIPs as a load balancer in an
active/active setup. I’m trying to set up call re-homing when
a node in the cluster goes down, largely following
<a
href="https://blog.opensips.org/2019/10/03/re-homing-your-calls-with-opensips-3-0/"
moz-do-not-send="true" class="moz-txt-link-freetext">
https://blog.opensips.org/2019/10/03/re-homing-your-calls-with-opensips-3-0/</a>
. I’ve got separate shtags lb1 and lb2 for each node.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When the cluster down is detected, I am
running a python script that sets the remaining node as active
then aims to rehome the calls in progress. Currently, that
works by getting dlg_list_ctx, then running
dlg_send_sequential for each dialog with a shtag matching the
down node (dialog[‘context’][‘values’][‘dlgX_shtag’].<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="p1">That’s fine for a few calls, but fails when we get
to a few hundred because the dlg_list_ctx throws an error:<br>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any ideas recommendations on how to tackle
this?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I could use dlg_list_ctx specifying an
index/counter to complete in batches, but I’m not quite sure
how the indexing works so there’s a worry we’d miss calls.
E.g. we do calls 0-40 then 41-80 but if call 0 ends while
processing 0-40, does that mean call 41 becomes call 40 so
it’s missed from the 41-80 batch.<o:p></o:p></p>
<p class="MsoNormal"><br>
Probably the best solution I have at the moment is to query
the DB directly to get the definitively list of call ids, then
run dlg_list_ctx specifying and iID then dlg_send_sequential
if appropriate. Or just don’t bother checking and run
dlg_send_sequential on them all.<o:p></o:p></p>
