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
       -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 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 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 spec-
	   ified, 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 rctladm.conf with the current configuration.
