smf_restarter - service management facility conventions for restarters


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

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.

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

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(8).

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. Note that no
known implementation honours this setting, and it
should be considered obsolete.

Service Reporting

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

The current state and next state, if currently in
transition, for instances stored in these properties.
See smf(7) for a description of the potential states.

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 cannot always be set and is always
cleared during transition out of any state. Each
restarter must define the precise list of auxiliary
states it uses.

The time when the current state was reached.

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