To define a physical memory resource cap for a project, establish a resident set size (RSS) cap by adding the rcap.max-rss attribute to the project database entry. This attribute sets the total amount of physical memory, in bytes, that is available to processes in the project.
For example, the following line in the /etc/project file sets an RSS cap of 10 Gbytes for a project named db.
db:100::db,root::rcap.max-rss=10737418240
You can also use the projmod command to set the rcap.max-rss attribute in the /etc/project file.
