BITS Settings

This property page lets you configure the settings used by the Microsoft* Background Intelligent Transfer Service (BITS) when transferring the application to a workstation. BITS is used only if Novell^® Application Launcher^TM and the application are configured to use BITS.

Minimum Retry Delay
If BITS encounters an error during transfer of the application, BITS classifies it as a fatal error or a transient error. BITS cannot recover from fatal errors; fatal errors require administrator intervention to fix the problem. BITS can possibly recover from transient errors.

Use this option to specify the minimum amount of time you want BITS to wait after a transient error occurs before trying to transfer the application again. The default is 600 seconds, or 10 minutes. The minimum setting is 60 seconds. The maximum setting is 2,147,483,647 seconds.

No Progress Timeout
Use this option to specify how many days you want BITS to continue to attempt to transfer the application after a transient error has occurred if no progress is being made.

• Use System Setting (Typically 14 Days): Select this option to use the Windows system setting. The Windows system setting comes from either 1) the BITS default setting, which is 14 days, or 2) the Timeout (Days) for Inactive Jobs setting in the Windows Group Policy, which is undefined by default. If you select this option, the BITS default setting (14 days) is used unless the Windows Group Policy setting has been assigned a value. You can use the Windows Group Policy Editor (gpedit.msc) to view and change the Windows Group Policy setting.
• Use Custom Setting: Select this option to manually enter a timeout period.
  • The minimum setting is 0 days. Enter 0 only if you do not want BITS to attempt to transfer the application again after it encounters a transient error; in this case, BITS immediately returns control of the transfer to Application Launcher.
  • The maximum setting is 24,855 days. However, BITS compares this number to the number in the Timeout (Days) for Inactive Jobs setting in the Windows Group Policy. If the Timeout (Days) for Inactive Jobs setting is less than this number, BITS uses the policy setting. For example, if you enter 45 days for this setting, but the policy is set to 30 days, BITS uses 30 days. If the Timeout (Days) for Inactive Jobs setting is undefined (the default state), the policy setting defaults to 90 days. In this case, for example, if you enter 91 days in this setting, BITS uses the policy setting (90 days).
    

If any transfer progress is made during the timeout period, the counter is reset. If BITS times out because no progress is being made, control of the transfer is returned to Application Launcher, which then transfers the application using its standard distribution process.

Priority
Use this option to assign a transfer priority level to the application. You can choose from one foreground priority and three background priorities (low, normal, high).

The foreground priority causes BITS to transfer the application in the foreground. Foreground transfers are the highest priority and are processed before any background transfers. Foreground transfers compete for network bandwidth with other applications, which can impede the user's network experience. Unless the timing of the transfer is critical or the user is actively waiting, you should use a background priority. In addition, BITS only supports foreground priority for files less than 2 GB.

For the three background priorities, the priority level determines when the transfer is processed relative to other transfers in the queue. Higher priority transfers preempt lower priority transfers. Transfers with the same priority level share transfer time, which prevents a large transfer from blocking the transfer queue. Lower priority transfers do not receive transfer time until all higher priority transfers are completed or are in an error state.
