A host is a computer that can run jobs and a host group is a collection of hosts, which enable you to define and run jobs on any of the computers within the host group.
For example, if you have a job that might require more resources than the host ID where the job runs, you can define the job to run on host group. If the host ID is not able to handle the job, it is routed to another host, which has more resources, or the job is set to a Wait status.
The load on any host computer or host group can be controlled. You can limit the usage of a host and the specific times when those limitations are applied. A host’s participation in a host group can also be defined for specific times. This helps you control the hosts available to the jobs in the active environment.
The following procedures describe how to create, edit, delete host groups, and remove hosts from host groups:
