Instead of maintaining Always-On Monitoring configuration in the file system on each node, all instances can share a common configuration. This allows a single configuration at one location to be modified and read from all the instances.

You use the following EMSCTL commands to modify properties:

• emsctl set_property

• emsctl unset_property

To obtain a list of current property values:

• emsctl list_properties

When a property is modified on one instance, all other Always-On Monitoring instances receive a JMS AQ message that tells them to refresh the value from the repository.
