If a service is currently running but needs to be restarted due to a configuration change or some other reason, the service can be restarted without you having to type separate commands to stop and start the service. The only reason to specifically disable and then enable a service is if changes need to be made before the service is enabled, and after the service is disabled.
Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
