Citrix Farm @ SLAC - Citrix XenApp 6.0
Citrix XenApp Good Practices
- Warning: Please make sure to
"logoff" once finish with the Citrix session. To properly
logoff, go to the 'Start Menu -> Logoff -> Ok'. Closing
the window or selecting 'Start Menu -> Disconnect' will merely
disconnect you, which means that your session is sill idled and still
using systems resources
and any opened files you may have. This could result in file locking
problems.
- MetaFrame servers are set to
disconnect and terminate users' session after 3 hours of idled time (no activity). We have
limited licenses, so please do not stay logged on if you are not using the
Farm. If you get disconnected while your files are opened, you might
end up with file locking problems and/or unsaved files.
- If a session freezes so that
you cannot properly log off, you should send email to 'windows-admin@slac.stanford.edu ''so that an administrator can log
you off or terminate your session properly.

How do I add printers to my Citrix
Session?
Any local printers you have configured on your client system are automatically mapped to your Citrix session.
Users are encouraged to configure printers on their local system before starting a Citrix session rather than configuring printers from within the Citrix session. If you need to add a printer from within a Citrix session, there is a central Citrix print server for this purpose.
To add a printer from within a Citrix session:

inactive Citrix session is disconnected?
Citrix sessions
left idle for 3 hours are automatically disconnected/terminated and any unsaved
data will be lost.
How do I map the drive of another Windows
computer at SLAC in my Citrix Session?
Network drives
on the SCS central servers (such as the user
home
directory (Z drive) or groups directories (V drive) are already
automatically mapped when you log into Citrix.
If you need to
map to other network drives at SLAC, follow the instructions below.
It is not
recommended that you share files this way through any client SLAC computers
(e.g., from your SLAC office computer), since such client computers are not backed
up nor reliable. User files should be stored in the user
home
directory (Z drive) or groups directories (V drive).
From the
Citrix Application dialog box, select 'Windows Desktop'.
After you get
the Windows desktop for the Citrix session, start Windows Explorer.
There are several ways you can start Windows Explorer, one way is to right
click on the computer icon in the Citrix session desktop.
In Windows
Explorer of the Citrix session, go to the Tools menu, select 'Map
Network Drive'.
Select a drive
letter, and in 'Folder' type in the name of the computer and share that
you want to map.
