Using rctladm

How to Use rctladm

Use the rctladm command to make runtime interrogations of and modifications to the global state of the resource controls facility. See the rctladm(1M) man page for more information.

For example, you can use rctladm with the -e option to enable the global syslog attribute of a resource control. When the control is exceeded, notification is logged at the specified syslog level. To enable the global syslog attribute of process.max-file-descriptor, type the following:

# rctladm -e syslog process.max-file-descriptor

When used without arguments, the rctladm command displays the global flags, including the global type flag, for each resource control.

# rctladm
process.max-port-events     syslog=off  [ deny count ]
process.max-msg-messages    syslog=off  [ deny count ]
process.max-msg-qbytes      syslog=off  [ deny bytes ]
process.max-sem-ops         syslog=off  [ deny count ]
process.max-sem-nsems       syslog=off  [ deny count ]
process.max-address-space   syslog=off  [ lowerable deny no-signal bytes ]
process.max-file-descriptor syslog=off  [ lowerable deny count ]
process.max-core-size       syslog=off  [ lowerable deny no-signal bytes ]
process.max-stack-size      syslog=off  [ lowerable deny no-signal bytes ]
