Administering Service Groups

The Web Console enables you to add and configure a service group according to the requirements of the resources. Use the Service Group page to bring service groups online and take them offline, as well as delete, switch, freeze, unfreeze, flush, enable, disable, and autoenable service groups. You can also enable and disable all resources in a service group, and clear a faulted group.
