Hi Ann ;)



The Service Management Facilty works a little bit different to the
Legacy Init System

In Case you have different Properties and groups


svc:	Service type
/system/system-log	Name
:default Instance

you will find your repository

at
bernd at kobold:/home/bernd$ ls /etc/svc
repository.db

its a sqlite based Database




The repository is the source for all known services on the system,
it imports the service manifest into the database and then never
references the manifest again.

The SMF Manifests are XML Scripts
with following content

Name of service
Number of instances
Start, stop and refresh methods
Property groups
Service model
Fault handling
Documentation template

 milestones are predefined sets of capabilities for a few set of
services, comparable  to  legacy run levels


If you want to know more about the services you could ask the Service
Management Facility about a detailled Description...

At example..


svcs -H -o FMRI,STATE,NSTATE,STIME,DESC -SSTATE svc:/*

If you would like to look on your legacy Services ==

If you would check your milestones. ;)



svcs -H -o FMRI,STATE,NSTATE,STIME,DESC -SSTATE svc:/milestone/*

 ---------------------------------------------------------------------
svc:/milestone/devices:default                     online         -
        10:37:46 device configuration milestone
svc:/milestone/multi-user:default                  online         -
        10:38:27 multi-user milestone
svc:/milestone/name-services:default               online         -
        10:37:59 name services milestone
svc:/milestone/single-user:default                 online         -
        10:37:58 single-user milestone
svc:/milestone/multi-user-server:default           online         -
        10:38:34 multi-user plus exports milestone
svc:/milestone/network:default                     online         -
        10:37:45 Network milestone

        10:38:05 Basic system configuration milestone
-----------------------------------------------------------------------



If you want to check on service/daemon

in this example you see the IPSec Daemon..

svcs -H -oDESC svc:/network/ipsec/ike:default ; svcs -H -oSTATE
svc:/network/ipsec/ike:default ; svcs -H -oFMRI,STATE -D
svc:/network/ipsec/ike:default ; svcs -l svc:/milestone/network:default ;

IKE daemon
disabled
svc:/milestone/network:default                     online
fmri         svc:/milestone/network:default
name         Network milestone
enabled      true
state        online
next_state   none
state_time   21 January 2011 10:37:45 CET
logfile      /var/svc/log/milestone-network:default.log
restarter    svc:/system/svc/restarter:default
dependency   require_all/none svc:/network/loopback (online)
dependency   require_all/none svc:/network/physical (multiple)
dependency   optional_all/restart svc:/network/ipfilter (disabled)
dependency   optional_all/none svc:/network/ipsec/policy (online)
dependency   optional_all/none svc:/network/ipsec/ike (disabled)
dependency   optional_all/none svc:/network/ipsec/ipsecalgs (online)
dependency   optional_all/none svc:/network/ipsec/manual-key (disabled)
