# Change Manager Host Object Types

Change Manager supports three host object types: managed hosts, host groups, and administrative domains. Change Manager can perform operations on managed hosts and host groups.

You can use host groups to create a hierarchy in which to organize managed hosts. Managed hosts can belong to one or more host groups, which enables you to view the same managed hosts from different perspectives.

You can organize the host groups and managed hosts in the following ways:

- Group like host types – For example, store all Netra X1 machines in a single host group. Do the same for other hardware types.

- Group managed hosts related to a particular service – Create a host group to hold all the managed hosts associated with a particular service. For example, a server farm manages web services. Therefore, create a host group named `WebServer`. In the `WebServer` host group, store the managed hosts used in the web server farm.

- Group managed hosts by geography – Create a host group to hold all the managed hosts that exist in a city, office suite, building, floor, or rack. For example, your company's Los Angeles office is located on the 6th floor. Therefore, create a host group named `6th floor`. In the `6th floor` host group, store the managed hosts that are on the 6th floor of your office.

- Group managed hosts by administrator – Create a host group to hold all the managed hosts administered by a system administrator. For example, Pat and Chris administer the managed hosts for your company. Therefore, create host groups named `pat` and `chris`. In the `pat` host group, store the managed hosts that are administered by Pat. Store Chris's managed hosts in the `chris` host group.

- Group managed hosts by organization – Create a host group to hold all the managed hosts for each organization. For example, group managed hosts for your marketing and engineering organizations. Therefore, create host groups named `marketing` and `engineering`.

## Host Group

A host group is a container that holds managed hosts and other host groups. Click a host group name to change into that host group and view its contents.

Perform the following actions from a host group:

- Create a host group

- Add a managed host

- Rename a managed host or host group

- Move a managed host or host group to another host group

- Remove a managed host or host group

## Managed Host

A managed host is a host that is managed by Change Manager. You can perform actions and run jobs on managed hosts.

Managed hosts in the Sun Management Center topology have a standard set of properties associated with them:

`Description`

  User-supplied string that describes the managed host.

`AgentPort`

  Port number the agent uses to communicate with the Change Manager server.

  Note –

  If you change the value of this property after installing a managed host, the Change Manager server will no longer be able to communicate with it. To reestablish communication with the server by using the new agent port, you must reinitialize the managed host by performing an initial installation on it.

`Owner`

  Read-only property that names the owner of the managed host.

`State`

  Read-only property that indicates the state of the managed host.

Modify the managed host's configuration by specifying the following:

- Ethernet address

- Platform group of the hardware

- Shared profile to use

- Values for archive-specific parameters

Perform the following actions on this managed host:

- Rename a managed host

- Copy a managed host to another host group

- Move the managed host to another host group

- Remove the managed host
