A Solaris service is any long-lived software object with a well-defined state, start and stop, and relationship to other services on the system. Delivering email, handling ftp requests, and permitting remote command execution are a few examples of services typically provided within the Solaris environment.
In Solaris 10, each software service has an advertised state. Should a failure occur, the system automatically diagnoses it and locates/pinpoints the source of the failure. Failing services are automatically restarted whenever possible, reducing the need for human intervention. Should manual intervention be required, system administrators can quickly identify the root cause of the service's failure and significantly reduce the times-to-repair and recover from said failure.
You can use the svcs -a
command to see a list of all of the
services on the system and their current state.

You can restrict the display to a particular service you are interested in
by using svcs svcname
, e.g. svcs apache2
to check
the status of the Apache webserver service. Note: you can also use
svcs http
for Apache.
# svcs apache2
STATE STIME FMRI
disabled Oct_06 svc:/network/http:apache2
Note: if you started the Apache webserver software with the apachectl
command, the svcs apache2
command will still show the
Apache service as "disabled", even though Apache itself is running, if you have
not enabled it to run as a service. You can enable Apache to run as a service
and start it running with svcadm enable apache2
. If you then check
its status with svcs
, you should see it in the "online" state.
# svcs apache2
STATE STIME FMRI
online 14:05:00 svc:/network/http:apache2
If you wish to see all process ids associated with the service you can
use the -p
option.
# svcs -p apache2
STATE STIME FMRI
online 14:05:00 svc:/network/http:apache2
14:05:00 7767 httpd
14:05:01 7768 httpd
14:05:01 7769 httpd
14:05:01 7770 httpd
14:05:01 7771 httpd
14:05:01 7772 httpd
To list all available information about the service, use the -l
option with the svcs
.
# svcs -l apache2
fmri svc:/network/http:apache2
name Apache 2 HTTP server
enabled true
state online
next_state none
