This topic describes the Distribution Preferences window in IBM
Director.
Introduction
Use
this window to perform the following tasks:
- Set up or restrict the access to the file-distribution server shares on
a selected system or group of systems.
- Set the streaming preference for the selected system or group.
- Set the maximum data rate for streaming software packages to the selected
system.
Fields
- Always stream to system(s)
- Selecting this option specifies that any software distribution package
is streamed (or copied) directly to the selected system or group before the
software is installed. A redirected installation from a server share cannot
be performed on the selected system or group if this option is selected.
Streaming
might be preferable if, for example, the target system is a dial-up mobile
system. If a streamed installation is suspended, it can be resumed. If an
installation from a file distribution server is suspended, the installation
must be restarted.
- Use File Distribution Server Shares
- Selecting this option specifies that the list of server shares, which
are defined to IBM Director,
are used to attempt redirected installations.
- Shares
- This window lists shares defined to IBM Director Server.
The default Universal Naming Convention (UNC) setting, \\*\*, indicates that
the selected system or group of systems can access any file distribution server
share that has been defined to IBM Director. If a redirected installation
of a software distribution package to a selected system is not possible, the
package is streamed.
- Add
- Displays a window in which you can add a server share location. You must
specify the location in UNC format.
- Edit
- Displays a window in which you can change the selected server-share entry.
- Remove
- Deletes the selected server-share entry.
- Restrict share selection to list
- If you select this check box, the server shares that are defined in this
window are the only shares that can be used by the selected system or group
of systems for a redirected installation.
- Stream from File Distribution Server
- If you select this check box, the contents of a software distribution
package are streamed to the selected system or group before installing the
software, instead of installing the software from the file distribution server.
Streaming
might be preferable if, for example, the target system is a dial-up mobile
system. If a streamed installation is suspended, it can be resumed. If an
installation from a file distribution server is suspended, the installation
must be restarted.
- Limit streaming bandwidth for system
- Select this check box to enable the setting of a limitation on the amount
of bandwidth used to stream software distribution packages to the selected
systems. If a limitation is set for one or more systems through this dialog:
- The bandwidth limitation applies to streaming from the IBM Director Server and
from all file distribution server shares.
- The lowest value of the two settings is used as the limitation parameter
if a bandwidth limitation is also set for streaming from the IBM Director Server.
Enter a streaming bandwidth in kilobits per second (kbps). For values
less than 1 kbps, enter a decimal amount. The minimum value is 0.25 which
indicates a bandwidth of 256 bytes per second.
註: You can also limit
streaming bandwidth to all systems through Software Distribution Server Preferences.
