Overview

Overview

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

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

Trino service actions
Action	Description
Add/Remove components	Running this action opens the component-host mapping interface where you can add, remove, and distribute Trino components
Check	Runs service-specific tests to check the health of the service and its components
Start	Starts the service. When you run this action, the option *Apply configs from ADCM* is available. If it is set to `true`, all service configurations defined in ADCM settings will be applied on the service startup. Otherwise, the service starts without applying configurations from ADCM
Stop	Stops the service
Restart	Restarts the service. When you run this action, the option *Apply configs from ADCM* is available. If it is set to `true`, all service configurations defined in ADCM settings will be applied during the service restart. Otherwise, the service restarts without applying configurations from ADCM
Remove	Removes the service from the cluster. This action should be used to remove already installed services. Whereas the control can be used to remove a non-mapped service (a service which components have not been distributed among cluster hosts)

The Trino has two components:

Trino Coordinator
Trino Worker

Both of them have the same set of available actions listed in the table below.

Trino components actions
Action	Description
Check	Verifies whether all the component instances in the cluster work correctly
Restart	Restarts all the component instances in the cluster
Start	Starts all the component instances in the cluster
Stop	Stops all the component instances in the cluster
