Resource Controls Tab
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.

How to Access the Resource Controls Tab
The Resource Controls tab is located under System Configuration in the Navigation pane.
To access Resource Controls, do the following:
- Click the System Configuration control entity in the Navigation pane.
- Double-click Projects.
- Click on a project in the console main window to select it.
- Select Properties from the Action menu.
- Click the Resource Controls tab.
View, add, edit, or delete resource control values for processes, projects, and tasks.
Resource Controls You Can Set
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:
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
Control Name |
Description |
Default Unit |
|---|
project.cpu-shares |
The number of CPU shares that
are granted to this project for use with the fair share scheduler (FSS)
(see the FSS(7) man page) |
Quantity (shares) |
task.max-cpu-time |
Maximum CPU time that is available to
this task's processes |
Time (seconds) |
task.max-lwps |
Maximum number of LWPs simultaneously available to this task's
processes |
Quantity (LWPs) |
process.max-cpu-time |
Maximum CPU time that is available to this process |
Time (seconds) |
process.max-file-descriptor |
Maximum file
descriptor index that is available to this process |
Index (maximum file descriptor) |
process.max-file-size |
Maximum file
offset that is available for writing by this process |
Size (bytes) |
process.max-core-size |
Maximum size of
a core file that is created by this process |
Size (bytes) |
process.max-data-size |
Maximum heap memory
that is available to this process |
Size (bytes) |
process.max-stack-size |
Maximum stack memory segment that is
available to this process |
Size (bytes) |
process.max-address-space |
Maximum amount of address space, as summed over
segment sizes, available to this process |
Size (bytes) |
Setting Values
You can view, add, edit, or delete resource control values for processes, projects,
and tasks. These operations are performed through dialog boxes in the 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.
