Updating Resource Controls

You can view and temporarily alter resource control values and actions on a per-process, per-task, or per-project basis by using prctl. A project, task, or process ID is given as input, and the command operates on the resource control at the level where it is defined.

Any modifications to values and actions become effective immediately. However, these modifications apply to the current session 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 deleted and their actions can 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.
