RCTLADM(1M)RCTLADM(1M)NAMErctladm - display or modify global state of system resource controls
SYNOPSISrctladm [-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 con‐
trol 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 viola‐
tions 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 dis‐
able 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 sys‐
log(3C). You can omit the common LOG_ prefix on the severity
level. Note that not all rctls support the syslog action. See
resource_controls(5).
-l
List information about rctls. The name, global event actions and
statuses, and global flags are displayed. If one or more name oper‐
ands are specified, only those rctls matching the names are dis‐
played.
-u
Configure resource controls based on the contents of /etc/rct‐
ladm.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 violations 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 specified
as operands.
2
Invalid command line options were specified.
FILES
/etc/rctladm.conf
Each time rctladm is executed, it updates the contents of rct‐
ladm.conf with the current configuration.
