While the system is quiet, complete any other routine maintenance, such as DATATEL.RESIZE.FILES, that needs to be done.

Next, from the command line, restart the auxiliary Colleague listeners with the following commands:

systemctl start colleague-prod
systemctl start colleague-test

All Colleague listeners should then be back up.  You can test this using the listdmi command. This should restart the listeners that were shut down to quiet the system.  

Next, we'll want to restart any services that were shut down when Colleague stopped, such as garbage collection, the EDX queue, and EPH.  The EDX queue can be restarted from EDQM.  Garbage collection and EPH are typically started with the commands from the datatel user's crontab.

/home/datatel/cronscripts/R18_wagc_production > /dev/null 2>&1
/home/datatel/cronscripts/R18_wagc_test > /dev/null 2>&1
/home/datatel/cronscripts/R18_wagc_development > /dev/null 2>&1
/home/datatel/cronscripts/envision.process.handler.sh > /tmp/datatel.eph_start.log 2>&1

All that remains is to reenable Self-Service from the load balancer and allow access to the UI from UIEC.  Once these are done, test access to Self-Service, Webadvisor, and the UI.
