However, Passive nodes do let you perform a limited number of processing functions, such as:
...
If an Agent fails, Universal Broker restarts it. The Agent then attempts to determine what tasks or functions were in process at the time of failure.

Warm Start Processing is a term used to refer to a process UAG goes through upon startup by which all task instances that were active at the time of the last shutdown (intentional or otherwise) are reviewed and proper action is taken based on state and platform.

In order to support such a determination, Agent task processing includes the following steps:
...
OMS provides for reliable message communication by persisting all OMS queued messages to persistent storage. The OMS Server maintains OMS queues in an OMS message database that resides on persistent storage.
See Universal Message Service (OMS) for detailed information on OMS.

To view a list of all cluster nodes, from the Agents & Connections navigation pane select System > Cluster Nodes. The Cluster Nodes list identifies all registered cluster nodes. The Mode column on the list identifies the current mode (status) of all cluster nodes.

A cluster node becomes registered the first time it starts. From then on, it always appears in the Cluster Nodes list, regardless of its current mode. |

All cluster nodes in a High Availability environment must point to the same database by making sure the following entries in their uc.properties files are the same.
For example:

OMS HA cluster configuration is described in the OMS Reference Guide.
The Universal Controller OMS Server definitions specify an OMS HA cluster as an ordered, comma-separated list of OMS Server addresses, one for each member of the OMS HA cluster.
...
If you want to configure an Agent to be able to access an OMS HA cluster, you must configure the Universal Automation Center Agent (UAG) OMS_SERVERS configuration option.
