NAME

       smf_restarter - service management facility conventions for restarters

DESCRIPTION

       All  service  instances  in the service management facility must be managed by a restarter. This manual page describes configuration, func-
       tionality, and reporting characteristics that are common to all restarters in the framework.   Characteristics  specific  to  a  particular
       restarter are described in the restarter's manpage.

       For  each  managed  service,  a restarter relies on retrieving properties on the service instance to determine configuration. The restarter
       manages a set of property groups to communicate the current disposition of a service with display tools such as svcs(1).

   Service configuration
       The common restarter configuration for all services is captured in the general property group. This group includes the  following  required
       and optional property settings.

       enabled                 This is a required property. If set, the restarter of an instance attempts to maintain availability of the service.

       restarter               This  is  an  optional  property  that  allows  the  specification  of an alternate restarter to manage the service
                               instance. If the restarter property is empty or absent, the restarter defaults to svc.startd(1M).

       single_instance         This is an optional property. When set, only one instance of the service is allowed to transition to an  online  or
                               degraded status at any time.

       transient_process       This is an optional property. When specified, the service does not contain objects that run indefinitely

   Service reporting
       All restarters report status using the restarter property group, which includes the following properties:

       next_state              The  current state and next state, if currently in transition, for instances stored in these properties. See smf(5)
                               for a description of the potential states.

       auxiliary_state         An astring with no spaces that contains a precise term to describe the full restarter-specific state in combination
                               with  the restarter state property.  The auxiliary state may not always be set and is always cleared during transi-
                               tion out of any state. Each restarter must define the precise list of auxiliary states it will use.

       state_timestamp         The time when the current state was reached.

       contract                The primary process contract ID, if any, under which the service instance is executing.
