High Availability and Clustering
When you are installing a high availability system, the installation includes a setup for the Config
Server (the primary server in a cluster). The cluster’s multicast address is configured automatically.
Fill in these values if you are installing a clustered or high availability system.
Here are some
clustering considerations . For additional details on clustering, refer to the
OpenManage Network Manager User Guide .
• Clustering does not require DNS entries for all servers.
• Servers (Application or Mediation) in a cluster need to share the following pieces of
information:
• Partition Name is a unique string for this cluster, beginning with a letter. For clustering,
configure this name one of several ways:
– Command line, typical for testing
– installed.properties, the command line overrides this property file
– pmstartup.dat, settings used by automatic server startup (i.e., Windows Service)
See Installing Distributed and HA Deployments on page 55 for a real-world example of
such an installation.
• Mediation Listeners as Redundant Peers for Mediation server clusters, you can also
elect to either send redundant messages to each server, or to have each server process
messages independently. Select the former for a high availability mediation pair.
