How to Set the Memory Cap Enforcement Threshold

Caps can be configured so that they will not be enforced until the physical memory available to processes is low. See Memory Cap Enforcement Threshold for more information.

The minimum (and default) value is 0, which means that memory caps are always enforced. To set a different minimum, follow this procedure.

1. Become root or assume an equivalent role.
2. Use the –c option of rcapadm to set a different physical memory utilization value for memory cap enforcement.

   # rcapadm -c percent

   percent is in the range 0 to 100. Higher values are less restrictive. A higher value means capped project workloads can execute without having caps enforced until the system's memory utilization exceeds this threshold.
