Several desktop applications and a suite of system management (SysMan) applications are integrated into the Common Desktop Environment (CDE). Most of these applications can be started from the Application Manager.
This chapter provides the following information:
You can start many desktop and SysMan applications from either the Application Manager or from the command line. Use one of the following methods to start applications:
To start an integrated application from the Application Manager:
Click the Application Manager icon on the Front Panel.
Double click the application group you want to access.
Double click on the application that you want to start.
To start an application from the command line, enter the
command name.
If the command location is not included in your
$PATH
variable, you must include the command's full pathname.
For example,
to start the Image Viewer application from the command line, you could type
the following:
$
/usr/bin/X11/dximageview &
The ampersand ( &
) at the end of the command line runs the application
in the background, letting you use the same terminal window to perform other
tasks.
Section 1.3.4.1 tells you how to find reference pages for commands and applications. The reference page tells you what command invokes the application, explains options, and provides the location of the command.
Other system management applications can be started from the SysMan Menu or the SysMan Station.
Section 5.5 explains how to use the SysMan Menu to get system management data and run selected system administration tasks.
Section 5.6 introduces the SysMan Station, a tool to help your system administrator manage either single systems and clusters.
5.2 Running Applications Across the Network
To run an application that is not installed on your system, you need network access and an account on a remote system where that application is installed. You can run the remote application and display the output on your system as though the application was running locally. Before you can do this, you must do the following:
You can use the Host Manager to display remotely run applications.
See the Host Manager online help volume for more information.
5.2.1 Authorizing Access to your System
To
display remotely run applications on your local system, use the
xhost
command to provide the remote host access to your display
before you log into the remote system.
For example, if the host name of the
remote machine is
trenton
, enter the following on your
system:
$
/usr/bin/X11/xhost +trenton
The remote system named
trenton
is added to the list of hosts that have access to your machine.
See the
xhost
(1X)
reference page for more information.
5.2.2 Enabling the Display
Once you have authorized the remote system access to your local system, log into the remote system and specify where you want to display the remotely run application.
The command you enter to enable the display varies depending on the operating system of the remote host you are using, and the shell you are using.
Use one of the following methods to enable the display:
If the remote host uses the C shell, enter the following at the system prompt:
setenv DISPLAY local_sysname:0
If the remote host uses the Bourne or Korn shell, enter the following at the system prompt:
DISPLAY=local_sysname:0
export DISPLAY
If the remote host is an OpenVMS system and the OpenVMS network host is running DECnet, enter the following at the system prompt:
set display/create/node=local_sysname
If the OpenVMS network host is running Transmission Control Protocol/Internet Protocol (TCP/IP), you can use the TCP/IP network transport as follows:
set display/create/transport=tcpip/node=local_sysname
If the name of your system appears in lowercase in the OpenVMS TCP/IP database
file, you must enclose the name of your local system in double quotes ("local_sysname"
).
If it does not, do
not use quotes.
Use the
hostname
command to see how your
system name is entered into the database file.
In the previous examples, local_sysname is the host name of the machine where you want the remote application to display.
Once you have authorized access to your system and enabled the display,
you can run the application from the remote machine by using the command name
as described in
Section 5.1.
The application then displays
on the system you specified.
5.3 Using Desktop Applications
Several desktop applications have been integrated into CDE. Your primary source of information about any of these applications is each application's online help volume. Table 5-1 highlights some of these applications.
Note
The desktop applications available on your system may depend upon the software subsets that you have loaded. This section does not list all desktop applications available.

5.4 Using System Management Applications
A suite of system management (SysMan) applications provide a graphical front-end to administrative commands for the person who administers your system.
Section 5.1 describes how to access and start the SysMan applications. You must have the appropriate privileges to use most of these applications. For information on using each application, see that application's online help volume. You can access the help volume by opening an application and clicking on the Help menu.
The suite of SysMan applications is divided into several categories,
shown in
Figure 5-6:
Figure 5-6: SysMan Categories in Application Manager
Use applications in this category to configure a system after installation. Ordinarily, you will not need to use these applications once your system is set up.
Use applications in this category for frequently performed system administration tasks.
Use applications in this category to monitor and tune your system after it is up and running.
Use applications in this category to install and manage additional software on your system.
Use applications in this category to monitor and manage file sytems.
Use applications in this category to display a variety of system statistics with the Display Window application. You can repeatedly display the same statistics to monitor progress or trends.
The SysMan Menu provides a hierarchical menu of system management tasks that can be used in several different user environments such as X Windows, web browsers, or character-based terminal displays. It can be started from the command line or from the CDE Application Manager. Authorized users also can invoke the SysMan Menu from the SysMan Applications Subpanel.
The SysMan Station provides a graphical topological representation
of the system and all its components, letting a system administrator visually
select system components and then run SysMan applications that apply
to that component.
The system administrator can use the SysMan Station
to manage both single systems and clusters.
You must be logged in as
root
to access the SysMan Station.
Note
The system management applications available on your system may depend upon the software subsets that you have loaded. This section does not list all of the system management applications available.
To find information about the applications in each SysMan application group, do the following:
Click the Help Manager control from the CDE Front Panel.
Click System Management.
Click Welcome to SysMan.
Scroll down, and click on one of the SysMan application groups.
Each SysMan application in the application group is described along with restrictions, configuration dependencies, and links to additional information such as the application's online help volume and reference page. You also can access the online help for any application by starting the application and selecting Help.
The following items, although not SysMan application categories, are also available from the Application Manager's System Administration selection.
