1rctladm(1M) System Administration Commands rctladm(1M)
2
6 rctladm - display or modify global state of system resource controls
7
9 rctladm [-lu] [-e action] [-d action] [name...]
10
13 The rctladm command allows the examination and modification of active
14 resource controls on the running system. An instance of a resource con‐
15 trol is referred to as an rctl. See setrctl(2) for a description of an
16 rctl; see resource_controls(5) for a list of the rctls supported in the
17 current release of the Solaris operating system. Logging of rctl viola‐
18 tions can be activated or deactivated system-wide and active rctls (and
19 their state) can be listed.
20 An rctladm command without options is the equivalent of an rctladm with
23 the -l option. See the description of -l below.
24
26 The following options are supported:
27 -d action
29 -e action
30 Disable (-d) or enable (-e) the global action on the specified
32 rctls. If no rctl is specified, no action is taken and an error
33 status is returned. You can use the special token all with the dis‐
34 able option to deactivate all global actions on a resource control.
35 You can set the syslog action to a specific degree by assigning a
37 severity level. To do this, specify syslog=level, where level is
38 one of the string tokens given as valid severity levels in sys‐
39 log(3C). You can omit the common LOG_ prefix on the severity level.
40 Note that not all rctls support the syslog action. See
41 resource_controls(5).
42 -l
45 List information about rctls. The name, global event actions and
47 statuses, and global flags are displayed. If one or more name oper‐
48 ands are specified, only those rctls matching the names are dis‐
49 played.
50 -u
53 Configure resource controls based on the contents of /etc/rct‐
55 ladm.conf. Any name operands are ignored.
56
59 The following operands are supported:
60 name
62 The name of the rctl to operate on. Multiple rctl names can be
64 specified. If no names are specified, and the list action has been
65 specified, then all rctls are listed. If the enable or disable
66 action is specified, one or more rctl names must be specified.
67
70 Example 1 Activating System Logging for Specific Violations
71 The following command activates system logging of all violations of
74 task.max-lwps.
75 # rctladm -e syslog task.max-lwps
78 #
79 Example 2 Examining the Current Status of a Specific Resource
83 The following command examines the current status of the task.max-lwps
86 resource.
87 $ rctladm -l task.max-lwps
90 task.max-lwps syslog=DEBUG
91 $
92
96 The following exit values are returned:
97 0
99 Successful completion.
101 1
104 A fatal error occurred. A message is written to standard error to
106 indicate each resource control for which the operation failed. The
107 operation was successful for any other resource controls specified
108 as operands.
109 2
112 Invalid command line options were specified.
114
117 /etc/rctladm.conf
118 Each time rctladm is executed, it updates the contents of rct‐
120 ladm.conf with the current configuration.
