Where OSD Script Runs

Where the script runs

The script can run in the following two locations:

• Inside the Virtual Environment
• Outside the Virtual Environment

Set the PROTECT attribute as follows:

• PROTECT=True
  This setting configures the script to run in the Virtual Environment. You can use this setting to run scripts that are used to troubleshoot issues.
• PROTECT=False
  This attribute configures the script to run outside the Virtual Environment. For example, you can use this setting to run scripts that copy files locally to the client.

When OSD Script Runs

When the script runs

You can use the .osd file to run scripts at various times during the startup of App-V (SoftGrid)-enabled programs. The "SCRIPT TIMING and EVENT" setting in the script comes first. Under this setting, the following attributes determine when the script runs:

• PRE STREAM
  This attribute runs the script before the program starts streaming. For example, use this attribute when you have to open a virtual private network (VPN) connection to the App-V (SoftGrid) server before you run the program.
• POST STREAM
  This attribute runs the script after authorization and after the program starts streaming but before the Virtual Environment is set up.
• PRE LAUNCH
  This attribute runs the script inside the virtual environment before the program runs.
• POST LAUNCH
  This attribute runs the script after the program is started.
• POST SHUTDOWN
  This attribute runs the script after the program is shut down. For example, use this attribute to clean up configuration settings or to delete configuration files.

How OSD script runs

How the script runs

The new TIMEOUT attribute determines the following:

• Whether the App-V (SoftGrid) client waits for the script to finish
• The period that the App-V (SoftGrid) client will wait for the script to finish

For backward compatibility, the WAIT attribute is still supported in Microsoft App-V 4.x and in Microsoft SoftGrid 4.x. 

Set these attributes as follows:

TIMEOUT
• TIMEOUT=x
  The client will wait x seconds for the script to finish before the client returns an error.
• TIMEOUT=0
  The client will wait indefinitely for the script to finish.

WAIT
• Wait=False
  The client will continue without waiting for the script to finish.
• Wait=True
  The client will not start the next step until the script finishes.

Notes

• The client does not support a pre-shutdown event. You cannot determine the exact moment at which a user will perform a shutdown. For example, you cannot predict when the user will clickClose or when the user will press ALT+F4.
• You can use scripts in any language. However, the language must be installed locally on the client computer.
