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
resource_controls(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 Disable (-d) or enable (-e) the global
-e action 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 deac-
tivate all global actions on a resource con-
trol.
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.
-l List information about rctls. The name, glo-
bal 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 speci-
fied. If no names are specified, and
the list action has been specified,
then all rctls are listed. If the
enable or disable action is speci-
fied, 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
$
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 A fatal error occurred. A message is written to
standard error to indicate each resource control
for which the operation failed. The operation was
successful for any other resource controls speci-
fied as operands.
