Auxiliary Parameters

Configuration of primary and secondary resource control parameters is important for security and stability of the whole system. Auxiliary parameters differ much from the primary and secondary parameters in this respect.

The main functions of auxiliary parameters are the following:

So, auxiliary parameters play a role similar to the limitations configurable through the setrlimit(2) interface and sysctl(8) in standard Linux installations (please see the Other Existing Resource Control Mechanisms subsection).

Because of this helper role in resource control, system management software may show auxiliary parameters in advanced mode for experienced administrators only and hide them in "basic" management modes.
