Checking Shared Memory Resource Controls

Use the prctl command to make runtime interrogations of and modifications to the resource controls associated with an active process, task, or project on the system.

To view the current value of project.max-shm-memory set for a project and system-wide:

# prctl -n project.max-shm-memory -i project default

default is the project ID obtained by running the id -p command.

For example, to change the setting for project.max-shm-memory to 6 GB for the project default without a reboot:

prctl -n project.max-shm-memory -v 6gb -r -i project default
