> <description>SCM, OM hosts will be able to resolve itself based on its host
> name instead of fqdn. It is useful for deploying to kubernetes
> environment, during the initial launching time when
> [pod_name].[service_name] is not resolvable yet because of the probe.

> <description>Disable the jvm network address cache. In environment such as

> Disabling this cache helps to quickly resolve the fqdn's to the new IPs.
