<font size=2 face="sans-serif">Hello Peter,</font><br><br><font size=2 face="sans-serif">Planned network outage is a lot easier
to handle than unexpected ones!</font><br><br><font size=2 face="sans-serif">At BnF, we paused all running jobs until
we have the confirmation everything is back to normal. We already did this
during broad crawls so for more than 60 cralwers.</font><br><font size=2 face="sans-serif">The challenge is to make sure you have
no new job to start, so we temporarily desactivate the Selective harvests.</font><br><font size=2 face="sans-serif">If we have jobs at a post-processing
stage that we cannot paused, we stop the HarvestController by putting a
shutdown.txt file in the job directory.. </font><br><br><font size=2 face="sans-serif">Best,</font><br><br><font size=2 face="sans-serif">Sara</font><br><br><br><br><font size=1 color=#5f5f5f face="sans-serif">De :

queues settings in the Open JMs broker properties and how long time there
is no network. Our installation breaks down if it loose the network
connection more than an 10 – 30 min..dependend on what’a running </font><br><font size=3 color=#004080 face="Calibri">If the message queues hIt
the maximum there is normally no other way than restart the whole platform
and all running harvesterjobs needs to be restarted. </font><br><font size=3 color=#004080 face="Calibri">You can try to restart the
GUI it will try to empty the JMS queues. And sometimes - after the network
is ok again - and you have patience and wait 2-3 hours the broker will
tries to resolve the messages queues and succeded to do it last time.</font><br><font size=3 color=#004080 face="Calibri"> </font><br><font size=3 color=#004080 face="Calibri">Best regards</font><br><font size=3 color=#004080 face="Calibri">Tue</font><br><font size=3 color=#004080 face="Calibri"> </font><br><font size=3 face="Calibri"><b>From:</b> NetarchiveSuite-users <netarchivesuite-users-bounces@ml.sbforge.org>
