Available Resource Controls

A list of the standard resource controls that are available in this release is shown in the following table.

The table describes the resource that is constrained by each control. The table also identifies the default units that are used by the project database for that resource. The default units are of two types:

Quantities represent a limited amount.
Indexes represent a maximum valid identifier.

Thus, project.cpu-shares specifies the number of shares to which the project is entitled. process.max-file-descriptor specifies the highest file number that can be assigned to a process by the open(2) system call.
