       smf_restarter - service management facility conventions for restarters

       All  service  instances in the service management facility must be man-
       aged 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  man-
       ages 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 man-
                               age 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 tran-
                               sition to an online or degraded status  at  any

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

   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 pre-
                               cise term to describe the  full  restarter-spe-
                               cific  state  in combination with the restarter
                               state property.  The auxiliary  state  may  not
                               always  be  set  and  is  always cleared during
                               transition 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.

       svcs(1), svc.startd(1M), service_bundle(4), smf(5), smf_method(5)
