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
     -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.

System Administration Commands                        rctladm(1M)



     -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
       $



EXIT STATUS
     The following exit values are returned:

     0

         Successful completion.

System Administration Commands                        rctladm(1M)



     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.
