Hosts
A host is an instance of MarkLogic Server. A host is not configured individually but as a member of a group. A host is added to the Default group if it is not joined to another group during the installation process. For example, in cases where MarkLogic is running in a single host environment, the host is added to the Default group.
Forests are created on hosts and added to a database to interact with HTTP, ODBC, and XDBC Servers running on the same or other hosts.
See Groups and Databases for more details on hosts as they relate to groups and databases.
A host is managed from both the Group and Hosts configuration screens.
Using the Admin Interface to manage hosts is covered here. Managing hosts programmatically is covered in Host Maintenance Operations in the Scripting Administrative Tasks Guide.
