rcapadm(8) System Administration Commands rcapadm(8)
NAME
rcapadm - configure resource capping daemon
SYNOPSIS
rcapadm
rcapadm [ [-n] -E | -D]
[-i {sample|mode}=value]....
[-z zonename -m maxvalue]
DESCRIPTION
The rcapadm command allows a user with the privileges described below
to configure various attributes of the resource capping daemon. If used
without arguments, rcapadm displays the current status of the resource
capping daemon. See rcapd(8) for more information.
In the current release of the Solaris operating system, rcapadm is
available to users with all privileges and to users who have the
Process Management profile in their list of profiles. The System Admin‐
istrator role includes the Process Management profile.
OPTIONS
-D
Disable the resource capping daemon so that it will not be started
when the system is booted. Also stop the resource capping daemon
now, if the -n option is not specified and it is currently running.
-E
Enable the resource capping daemon so that it will be started each
time the system is booted. Also start the resource capping daemon
now, if the -n option is not specified and it is not currently run‐
ning.
-i {sample|mode}=value,....
Set configuration for rcapd operations. Two parameters that are
used by rcapd can be set by using this option.
sample The interval of sampling resident set size for collec‐
tions. The default sample interval is 30 seconds. The
minimum value is 5 seconds.
mode Set the mode of operation for rcapd. You can either set
the mode for rcapd to just log the results of the scan or
enforce the rss caps by paging out resident pages.
The following values are allowed by mode:
log-only Do not enforce caps. Log the rss cap and us‐
age statistics for all capped collections.
pageout Pageout resident pages for processes of col‐
lections that are above their rss caps. This
is the default mode for rcapd(8).
-m maxvalue
Used in conjunction with the -z option. Specifies a value for
rcap.max-rss, a dynamically-set cap on the usage of physical memory
for the zone specified by -z. You can apply a scale (K, M, G, T) to
the value you specify. K means kilobyte; M, megabyte; G, gigabyte;
and T, terabyte. For example, 100M is 100 megabytes.
To remove an existing cap, specify 0.
-n
Do not affect the running state of the resource capping daemon when
enabling or disabling it.
-z zonename
Used in conjunction with the -m option. Specifies the zone for
which you are dynamically specifying a cap on physical memory usage
(using -m).
Note -
To set a persistent cap on memory usage within a zone, use
zonecfg(8).
EXAMPLES
Example 1 Configuring the Resource Capping Daemon with Memory Cap En‐
forcement With a 5 Second RSS Sampling Interval
# rcapadm -E -i sample=5,mode=pageout
Example 2 Configuring the Resource Capping Daemon With Log Mode and a
60 Second RSS Sampling Interval
# rcapadm -E -i sample=60,mode=log-only
Example 3 Specifying a Resource Cap for a Zone
The command shown below specifies the maximum amount of memory that can
be consumed by a specified zone. Note that this value lasts only until
the next reboot. To set a persistent cap, use zonecfg(8).
# rcapadm -z testzone -m 512M
EXIT STATUS
The following exit values are returned:
0 Successful completion. The modifications to the current configura‐
tion were valid and made successfully.
1 An error occurred. A fatal error occurred either in obtaining or
modifying the resource capping configuration.
2 Invalid command-line options were specified.
