Core configuration service management via ADCM

Vladimir Adamenkov

The ADCM UI provides actions to manage the Core configuration service and its components. For information on how to run service actions, refer to ADH service actions.

The actions available for the Core configuration service are listed in the table below.

Core configuration service actions
