Resource controls allow you to associate a project with a set of resource constraints. These constraints determine the allowable resource usage of tasks and processes that run in the context of the project.
Figure 15-2 Resource Controls Tab in the Solaris Management Console
The Resource Controls tab is located under System Configuration in the Navigation pane. To access Resource Controls, do the following:
View, add, edit, or delete resource control values for processes, projects, and tasks.
The following table shows the resource controls that can be set in the console. 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.
Table 15-1 Standard Resource Controls Available in the Solaris Management Console
Resource controls and values are viewed in tables in the console. The Resource Control column lists the resource controls that can be set. The Value column displays the properties that are associated with each resource control. In the table, these values are enclosed in parentheses, and they appear as plain text separated by commas. The values in parentheses comprise an “action clause.” Each action clause is composed of a threshold, a privilege level, one signal, and one local action that is associated with the particular threshold. Each resource control can have multiple action clauses, which are also separated by commas.
Note - On a running system, values that are altered in the project database through the console only take effect for new tasks that are started in a project.
