System Administration Commands rctladm(1M)
NAME
rctladm - display or modify global state of system resource
controls
SYNOPSIS
rctladm [-lu] [-e action] [-d action] [name...]
DESCRIPTION
The rctladm command allows the examination and modification
of active resource controls on the running system. An
instance of a resource control is referred to as an rctl.
See setrctl(2) for a description of an rctl; see
resourcecontrols(5) for a list of the rctls supported in
the current release of the Solaris operating system. Logging
of rctl violations can be activated or deactivated system-
wide and active rctls (and their state) can be listed.
An rctladm command without options is the equivalent of an
rctladm with the -l option. See the description of -l below.
OPTIONS
The following options are supported:
-d action
-e action
Disable (-d) or enable (-e) the global action on the
specified rctls. If no rctl is specified, no action is
taken and an error status is returned. You can use the
special token all with the disable option to deactivate
all global actions on a resource control.
You can set the syslog action to a specific degree by
assigning a severity level. To do this, specify
syslog=level, where level is one of the string tokens
given as valid severity levels in syslog(3C). You can
omit the common LOG prefix on the severity level. Note
that not all rctls support the syslog action. See
resourcecontrols(5).
-l
List information about rctls. The name, global event
actions and statuses, and global flags are displayed. If
one or more name operands are specified, only those
rctls matching the names are displayed.

-u
Configure resource controls based on the contents of
/etc/rctladm.conf. Any name operands are ignored.
OPERANDS
The following operands are supported:
name
The name of the rctl to operate on. Multiple rctl names
can be specified. If no names are specified, and the
list action has been specified, then all rctls are
listed. If the enable or disable action is specified,
one or more rctl names must be specified.
EXAMPLES
Example 1 Activating System Logging for Specific Violations
The following command activates system logging of all viola-
tions of task.max-lwps.
# rctladm -e syslog task.max-lwps
#
Example 2 Examining the Current Status of a Specific
Resource
The following command examines the current status of the
task.max-lwps resource.
$ rctladm -l task.max-lwps
task.max-lwps syslog=DEBUG
