<div dir="ltr">Depends on the volume of your systems... I tried this as well, but rhn_check initially makes HTTPS calls and with 6,000+ systems it overwhelmed the Apache instances and caused deadlocks in the Postgres databases (even with Apache and pgsql variables increased).<div><br></div><div>I ended up switching the jabberd database to SQLite and it made a lot of difference over the default Berkeley DB.</div><div><br></div><div>For systems going offline, we have a few lines in our Puppet configs to restart OSAD on stale connections on a daily basis. To debug your own connection issues, I recommend increasing the debug value for OSAD in /etc/sysconfig/rhn/osad.conf (debug = 9) then restart OSAD, to see if you can narrow down what might be causing the systems to go offline. If it's not at the clients you might be able to find something at the server, somewhere in /var/log/rhn or so.</div><div><br></div><div><div> $date = strftime("%F")</div><div> $datetime = strftime("%F @ %T")</div><div> exec { "restart_osad_on_conn_error":</div><div> command => "/sbin/service osad restart",</div><div> onlyif => "/bin/grep -q '^${date}.*Unable to connect to jabber servers' /var/log/osad && sed -i 's/Unable to connect to jabber servers/fixed on ${datetime} by spacewalk::c_osad.pp/g' /var/log/osad",</div><div> }</div><div> exec { "restart_osad_on_stale_conn":</div><div> command => "/sbin/service osad restart",</div><div> onlyif => "/bin/netstat -an | /bin/grep -q ':5222.*CLOSE_WAIT'",</div><div> }</div></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Tue, Jan 17, 2017 at 5:33 AM Zeal Vora <<a href="mailto:zeal@freecharge.com">zeal@freecharge.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr" class="gmail_msg">Hi<div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">Thanks for the inputs everyone.</div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">Basically we need the rpm's to be installed in real time ( around 2-3 minutes delay is fine ) from SpaceWalk.
