NAME

       rcapadm - configure resource capping daemon

SYNOPSIS

       rcapadm

       rcapadm [ [-n]  -E | -D] [ -i interval=value,...,interval=value] [-c percent]

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 if it has been  configured.  See  rcapd(1M)  for
       more information.

       In  the	current  release of the Solaris operating environment, rcapadm is available to users with all privileges and to users who have the
       Process Management profile in their list of profiles. The System Administrator role includes the Process Management profile.

OPTIONS

       -n

	   Do not affect the running state of the resource capping daemon when enabling or disabling it.

       -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 running.

       -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.

       -i interval=value,...,interval=value

	   Set intervals for various periodic operations performed by rcapd. All intervals are specified in seconds. You  can  set  the  following
	   intervals:

	   scan

	       The interval at which rcapd scans for new processes. The default scan interval is every 15 seconds. The minimum value is 1 second.

	   sample

	       The interval of process resident set size sampling. The default sample interval is every 5 seconds. The minimum value is 1 second.

	   report

	       The  interval  at  which  various paging statistics are updated by rcapd, in seconds. These statistics can be viewed by using rcap-
	       stat(1SRM).  The default reporting interval is every 5 seconds. When the interval is set to 0, statistics will not be updated.

	       Note -  Paging refers to the act of relocating portions of memory, called pages, to or from physical memory. rcapd  pages  out  the
		       most infrequently used pages.

	   config

	       The reconfiguration interval, in seconds. At each reconfiguration event, rcapd checks its configuration file for updates, and scans
	       the project databases for new project caps. The default reconfiguration interval is every 60 seconds. The minimum  interval  is	0.
	       When the interval is set to 0, no periodic reconfiguration occurs, although the running daemon can still be reconfigured by sending
	       it SIGHUP.

       -c percent

	   Set the minimum physical memory utilization for memory cap enforcement. Caps will not be enforced until the physical  memory  available
	   to  processes  is low. The percent value should be in the range 0 to 100. The minimum (and default) value is 0, which means that memory
	   caps are always enforced.

EXAMPLES

       Example 1: Configuring the Resource Capping Daemon with Immediate Enforcement

       # rcapadm -E -i scan=15,sample=5,report=5,config=60 -c 0

EXIT STATUS

       The following exit values are returned:

       0	Successful completion. The modifications to the current configuration 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.
