Hosts
Within the enterprise, hosts are used to manage nodes. A host can contain nodes from more than one environment. Hosts are responsible for deploying applications and for other administrative tasks. Each host has a software repository that contains the application templates, features, and resource adapters available to the nodes managed by that host.
Hosts have types, but the only type currently supported is TIBCO Host.
A host is bound to a single Administrator server at a time. Hosts can contain nodes from multiple environments within one Administrator server.
ActiveMatrix enables isolation of hosts so that enterprises can separate different groups and services. The features are given below:
- A host can be part of any number of environments.
- If the host association is changed from All Environments to Specific Environments, support for nodes already running on the host continues.
- Node creation on the isolated host is limited to users in the associated environment or group of environments. Host not associated with an environment is hidden.
- It is not possible to remove a host from an environment if nodes for that environment are running on the host.
The host that manages the SystemNode node on which the Administrator server runs is named SystemHost.
