SVCCFG(1M) Maintenance Commands SVCCFG(1M)


NAME


svccfg - import, export, and modify service configurations

SYNOPSIS


/usr/sbin/svccfg [-v] [-s FMRI]


/usr/sbin/svccfg [-v] [-s FMRI] subcommand [args]...


/usr/sbin/svccfg [-v] [-s FMRI] -f command-file


DESCRIPTION


The svccfg command manipulates data in the service configuration
repository. svccfg can be invoked interactively, with an individual
subcommand, or by specifying a command file that contains a series of
subcommands.


Changes made to an existing service in the repository typically do not
take effect for that service until the next time the service instance is
refreshed. See the refresh subcommand on the svcadm(1M) man page for
more details.

OPTIONS


The following options are supported:

-f command-file

Reads and executes svccfg subcommands from command-file.


-s FMRI

Selects the entity indicated by FMRI (a fault management resource
identifier) before executing any subcommands. See smf(5).


-v

Verbose.


SUBCOMMANDS


Subcommands are divided into the categories specified in the subsections
that follow.


All subcommands that accept FMRIs also accept abbreviated or globbed
patterns. Instances and services can be abbreviated by specifying the
instance name, or the trailing portion of the service name. For example,
given the FMRI:

svc:/network/smtp:sendmail


All the following are valid abbreviations:

sendmail
:sendmail
smtp
smtp:sendmail
network/smtp


While the following are invalid:

mail
network
network/smt


Abbreviated forms of FMRIs are unstable, and should not be used in
scripts or other permanent tools. If a pattern matches more than one
instance or service, an error message is printed and no action is taken.

General Subcommands


end
exit
quit

Exits immediately.


repository repfile

Uses repfile as a repository. By default, svccfg(1M) uses the system
repository.

Use repository only with files from the identical version of Solaris,
including updates, that you are currently running. Do not use this
subcommand with the system repository, /etc/svc/repository.db.


set [-v|-V]

Sets optional behavior. If no options are specified, set displays the
options currently in effect.

-v

Turns on verbose mode.


-V

Turns off verbose mode.


Service Profile Subcommands


apply [-n] file

If a file is a service profile, properties, including
general/enabled, that are specified in the file are modified in the
SMF repository. Not-yet-existent properties and property groups will
be created. The type of the pre-existing property groups will not be
changed by the profile. Existing properties (as distinguished from
property groups) can have their type changed by the profile.
Nonexistent services and instances are ignored. Services and
instances modified by the profile will be refreshed. If -n is
specified, the profile is processed and no changes are applied to the
SMF repository. Any syntax error found will be reported on stderr and
an exit code of 1 will be returned. See smf(5) for a description of
service profiles. This command requires privileges to modify
properties in the service and instance. See smf_security(5) for the
privileges required to modify properties. If file is not a service
profile, the subcommand fails.


extract [> file]

Prints a service profile which represents the enabled status of the
service instances in the repository to standard output. The output
may be redirected to a file.


Service Manifest Subcommands


archive [-a]

Dumps a full XML service description for all services, instances, and
their persistent properties in the repository. This does not include
transient properties such as service state, and is suitable for a
relocatable repository backup.

Without the -a option, property groups containing protected
information (identified by the presence of the read_authorization
property--see smf_security(5)) will be archived without their
property values. When the -a option is specified, all values will be
archived. An error results if there are insufficient privileges to
read these values.


export [-a] service_FMRI [>file]

The service description for the specified service and its instances
is written to standard output or redirected to the given file.
Dependencies with a boolean "external" property set to true are
omitted in the belief that they were created on behalf of another
service.

Without the -a option, property groups containing protected
information (identified by the presence of the read_authorization
property--see smf_security(5)) will be exported without their
property values. When the -a option is specified, all values will be
archived. An error results if there are insufficient privileges to
read these values.

Note that export requires a service FMRI. To ease the use of
arguments cut and pasted from other command output, if you specify a
complete instance FMRI, the entire corresponding service including
all instances is exported and a warning is issued. If you specify an
abbreviation, such as apache2 or sendmail, that specifies an
instance, the command fails.


import [-V] file

If file is a service manifest, then the services and instances it
specifies are imported into the repository. According to the file,
dependencies may be created in other services. See smf(5) for a
description of service manifests. See smf_security(5) for the
privileges required to create and modify service configurations.

Services and instances in the manifest will be validated against
template data in the manifest and the repository, and warnings will
be issued for all template violations. See smf_template(5) for a
description of templates. If the -V option is specified, manifests
that violate the defined templates will fail to import. In
interactive invocations of svccfg, -V is the default behavior.

For existing services and instances, properties which have not
changed since the last import snapshot was taken are upgraded to
those specified by the manifest. Conflicts (properties which have
been changed both in the repository and the manifest) are reported on
the standard error stream. svccfg will never upgrade the
"general/enabled" and "general/restarter" properties, since they
represent administrator preference.


inventory file

If file is determined to be a service manifest, then the FMRIs of the
services and instances the file describes are printed. For each
service, the FMRIs of its instances are displayed before the FMRI of
the service.


restore

Restores the contents of the repository from a full XML service
description previously created by the archive subcommand. If the
archive was generated without the use of the -a option, the contents
of the repository following completion of the restore will not
include the values of any read-protected properties (see
smf_security(5)). If these are required, they must be restored
manually.

Restoring an archive which is inconsistent with currently installed
software (including patch revisions) might yield unpredictable
results. Therefore, prior to restoring an archive, all system and
application software, including any service manifests, should be
restored to the same state it was in at the time the archive was
made.


validate [file | fmri]

The validate subcommand can operate on a manifest file, an instance
FMRI, or the current instance or snapshot entity selection. When an
argument is specified, svccfg will check to see whether the specified
file exists. If the file exists, it will be validated. If a file of
the specified name does not exist, the argument is treated as an FMRI
pattern. If a conflict arises between a filename and an FMRI, use the
svc: and file: prefixes to tell svccfg how to interpret the argument.

When you specify a file, the file is processed in a manner similar to
import -V, but no changes are made to the repository. If any errors
are detected, svccfg displays the errors and exits with a nonzero
exit status.

For an instance fmri, instance entity selection, or snapshot entity
selection, the specified instance in its composed form (see
"Properties and Property Groups" in smf(5)) will be validated against
template data in the repository. Instance FMRIs and instance entity
selections use the "running" snapshot for validation. Warnings will
be issued for all template violations. See smf_template(5) for a
description of templates.


Entity Selection, Modification, and Navigation Subcommands
An "entity" refers to a scope, service, or service instance.

add name

A new entity with the given name is created as a child of the current
selection. See smf_security(5) for the privileges required to create
entities.


delete [-f] {name | fmri}

The named child of the current selection or the entity specified by
fmri is deleted. Attempts to delete service instances in the "online"
or "degraded" state will fail unless the -f flag is specified. If a
service or service instance has a "dependents" property group of type
"framework", then for each of its properties with type "astring" or
"fmri", if the property has a single value which names a service or
service instance then the dependency property group in the indicated
service or service instance with the same name as the property will
be deleted. See smf_security(5) for the privileges required to delete
service configurations.


list [pattern]

The child entities of the current selection whose names match the
glob pattern pattern are displayed (see fnmatch(5)). ':properties' is
also listed for property-bearing entities, namely services and
service instances.


select {name | fmri}

If the argument names a child of the current selection, it becomes
the current selection. Otherwise, the argument is interpreted as an
FMRI and the entity that the argument specifies becomes the current
selection.


unselect

The parent of the current selection becomes the current selection.


Property Inspection and Modification Subcommands


addpg name type [flags]

Adds a property group with the given name and type to the current
selection. flags is a string of characters which designates the flags
with which to create the property group. 'P' represents
SCF_PG_FLAG_NONPERSISTENT (see scf_service_add_pg(3SCF)). See
smf_security(5) for the privileges required to create property
groups.


addpropvalue pg/name [type:] value

Adds the given value to a property. If type is given and the property
exists, then if type does not agree with the property's type, the
subcommand fails. The values may be enclosed in double-quotes. String
values containing double-quotes or backslashes must be enclosed by
double-quotes and the contained double-quotes and backslashes must be
quoted by backslashes. Nonexistent properties are created, in which
case the type specifier must be present. See scf_value_create(3SCF)
for a list of available property types. See smf_security(5) for the
privileges required to modify properties. The new value will be
appended to the end of the list of property values associated with
the property.


delpg name

Deletes the property group name of the current selection. See
smf_security(5) for the privileges required to delete property
groups.


delprop pg[/name]

Deletes the named property group or property of the current
selection. See smf_security(5) for the privileges required to delete
properties.


delpropvalue pg/name globpattern

Deletes all values matching the given glob pattern in the named
property. Succeeds even if no values match. See smf_security(5) for
the privileges required to modify properties.


describe [-v] [-t] [propertygroup/property]

Describes either the current or the possible settings.

When invoked without arguments, describe gives basic descriptions (if
available) of the currently selected entity and all of its currently
set property groups and properties. A property group or specific
property can be queried by specifying either the property group name,
or the property group name and property name, separated by a slash
(/), as an argument.

The -v option gives all information available, including descriptions
for current settings, constraints, and other possible setting
choices.

The -t option shows only the template data for the selection (see
smf_template(5)), and does not display the current settings for
property groups and properties.


editprop

Comments of commands to reproduce the property groups and properties
of the current selection are placed in a temporary file and the
program named by the EDITOR environment variable is invoked to edit
it. Upon completion, the commands in the temporary file are executed.
The default editor is vi(1). See smf_security(5) for the privileges
required to create, modify, or delete properties.


listpg [pattern]

Displays the names, types, and flags of property groups of the
current selection. If an argument is given, it is taken as a glob
pattern and only property groups with names which match the argument
are listed.

In interactive mode, a basic description of the property groups is
also given.


listprop [pattern]

Lists property groups and properties of the current selection. For
property groups, names, types, and flags are listed. For properties,
names (prepended by the property group name and a slash (/)), types,
and values are listed. See scf_value_create(3SCF) for a list of
available property types. If an argument is supplied it is taken as a
glob pattern and only property groups and properties with names which
match the argument are listed.


setenv [-i | -s] [-m method_name] envvar value

Sets a method environment variable for a service or instance by
changing the "environment" property in the method_name property
group, if that property group has type "method". If method_name is
not specified and the -i option is used, the "method_context"
property group is used, if an instance is currently selected. If the
-s option is used and a service is currently selected, its
"method_context" property group is used. If the -s option is used and
an instance is currently selected, the "method_context" property
group of its parent is used. If neither the -i option nor the -s
option is used, the "start" property group is searched for in the
currently selected entity and, if an instance is currently selected,
its parent is also searched. If the "inetd_start" property group is
not located, it is searched for in a similar manner.

Once the property is located, all values which begin with envvar
followed by a "=" are removed, and the value "envvar=value" is added.
See smf_security(5) for the privileges required to modify properties.


setprop pg/name = [type:] value
setprop pg/name = [type:] ([values ...])

Sets the name property of the pg property group of the current
selection to the given values of type type. See
scf_value_create(3SCF) for a list of available property types. If the
property already exists and the type disagrees with the existing type
on the property, the subcommand fails. Values may be enclosed in
double-quotes. String values which contain double-quotes or
backslashes must be enclosed by double-quotes and the contained
double-quotes and backslashes must be quoted by backslashes. If the
named property does not exist, it is created, as long as the type is
specified. See smf_security(5) for the privileges required to create
or modify properties. Multiple values will be stored in the order in
which they are specified.


unsetenv [-i | -s] [-m method_name] envvar value

Removes a method environment variable for a service or instance by
changing the "environment" property in the method_name property
group, if that property group has type "method". If method_name is
not specified and the -i option is used, the "method_context"
property group is used, if an instance is currently selected. If the
-s option is used and a service is currently selected, its
"method_context" property group is used. If the -s option is used and
an instance is currently selected, the "method_context" property
group of its parent is used. If neither the -i option nor the -s
option is used, the "start" property group is searched for in the
currently selected entity and, if an instance is currently selected,
its parent is also searched. If the "inetd_start" property group is
not located, it is searched for in a similar manner.

Once the property is located, all values which begin with envvar
followed by "=" are removed. See smf_security(5) for the privileges
required to modify properties.


Snapshot Navigation and Selection Subcommands


listsnap

Displays snapshots available for the currently selected instance.


revert [snapshot]

Reverts the properties of the currently selected instance and its
service to those recorded in the named snapshot. If no argument is
given, use the currently selected snapshot and deselect it on
success. The changed property values can be made active via the
refresh subcommand of svcadm(1M). See smf_security(5) for the
privileges required to change properties.


selectsnap [name]

Changes the current snapshot to the one named by name. If no name is
specified, deselect the currently selected snapshot. Snapshots are
read-only.


Instance Subcommands


refresh

Commit the values from the current configuration to the running
snapshot, making them available for use by the currently selected
instance. If the repository subcommand has not been used to select a
repository, direct the instance's restarter to reread the updated
configuration.


EXAMPLES


Example 1: Importing a Service Description




The following example imports a service description for the seismic
service in the XML manifest specified on the command line.


# svccfg import /var/svc/manifest/site/seismic.xml


Note that the manifest must follow the format specified in
service_bundle(4).


Example 2: Exporting a Service Description




To export a service description on the local system:


# svccfg export dumpadm >/tmp/dump.xml


Example 3: Deleting a Service Instance




To delete a service instance:


# svccfg delete network/inetd-upgrade:default


Example 4: Checking Properties in an Alternate Repository




To examine the state of a service's properties after loading an alternate
repository, use the sequence of commands shown below. One might use such
commands, for example, to determine whether a service was enabled in a
particular repository backup.


# svccfg
svc:> repository /etc/svc/repository-boot
svc:> select telnet:default
svc:/network/telnet:default> listprop general/enabled
general/enabled boolean false
svc:/network/telnet:default> exit


Example 5: Enabling Debugging




To modify LD_PRELOAD for a start method and enable the use of
libumem(3LIB) with debugging features active:


$ svccfg -s system/service setenv LD_PRELOAD libumem.so
$ svccfg -s system/service setenv UMEM_DEBUG default


Example 6: Using describe Subcommand




The following command illustrates the use of the describe subcommand.


# svccfg -s console-login describe ttymon
ttymon application
ttymon/device astring /dev/console
terminal device to be used for the console login prompt
ttymon/label astring console
appropriate entry from /etc/ttydefs
...


ENVIRONMENTAL VARIABLES
