Values changed in the project database only become effective for new tasks that are started in a project. However, you can use the rctladm and prctl commands to update resource controls on a running system.
The rctladm command affects the global logging state of each resource control on a system-wide basis. This command can be used to view the global state and to set up the level of syslog logging when controls are exceeded.
You can view and temporarily alter resource control values and actions on a per-process, per-task, or per-project basis by using the prctl command. A project, task, or process ID is given as input, and the command operates on the resource control at the level where the control is defined.
Any modifications to values and actions take effect immediately. However, these modifications apply to the current process, task, or project only. The changes are not recorded in the project database. If the system is restarted, the modifications are lost. Permanent changes to resource controls must be made in the project database.
All resource control settings that can be modified in the project database can also be modified with the prctl command. Both basic and privileged values can be added or be deleted. Their actions can also be modified. By default, the basic type is assumed for all set operations, but processes and users with superuser privileges can also modify privileged resource controls. System resource controls cannot be altered.
