A High Availability (HA) installation consists of several processes: Each node of the HA network has either the UMS Server or the UMS Load Balancer or both running, depending on the configuration you have chosen during the installation process of the UMS HA, see also Configuration Options. In addition, the UMS Watchdog always runs on each node.
|UMS Load Balancer|
If both the UMS Server and the UMS Load Balancer are running on the same server, the UMS Server uses port 30002 and the UMS Load Balancer uses port 30001. If only the UMS Server is installed on a server, it always listens on port 30001. See IGEL UMS Communication Ports.
The following table shows how you can find out which HA processes are running and how/where you can stop or start them.
