Hotfix for Citrix XenDesktop 5.6 broker service

New Fixes in This Release

  1. When using Concurrent User (CCU) licensing, the licenses might fail to check-in, eventually resulting in a shortage of licenses. The administrator is required to restart the Desktop Delivery Controller or the license server to return it to the original state. The issue occurs when there is a mismatch in the search result while using the case-sensitive string comparator. As a result, the record of the licenses might not be found while releasing the license.

  2. Administrators with “Machine administrator” privileges cannot view or create personal vDisk resources (“Pooled with personal vDisk” and “Streamed with personal vDisk”) in Desktop Studio.

Fixes from Replaced Hotfixes

  1. Note: This is a feature enhancement that requires you to install both a Broker Service and a Broker Service PowerShell Snap-in hotfix that contains Fix #LA0754.

    Description: Failure of a hypervisor or a loss of connectivity between the hypervisor and the Broker renders an active session inaccessible, and attempts to reconnect to the session fail. For shared desktops, and in the common case where a user is entitled only to a single desktop from a group, the user effectively loses all access to that desktop group, even if other machines in the same group (but on a different hypervisor) are available for use. For large hypervisors in a data center, such loss of a hypervisor can cause a large scale reduction of availability of XenDesktop that requires significant operator intervention to remedy.

    With this feature enhancement:

    • a new session can be brokered from the existing infrastructure
    • sessions orphaned as a result of hypervisor failure or of a loss of connectivity can be enumerated and terminated from the console

    Background: This feature enhancement adds a new “hidden” attribute to every session. With the “hidden” attribute set to “false” (default), XenDesktop behaves entirely as in earlier releases. To avoid a loss of desktop availability in the event of hypervisor failure, the Broker automatically marks a session as hidden (“hidden” = “true”) the moment a user attempts to reconnect to that session. With the session marked hidden this way, the Broker continues with the session launch as if no session was found to which to reconnect. Provided sufficient desktops are available, a new session is created on a different desktop – even if the user’s entitlement to that resource would ordinarily be exhausted.

    • To enumerate orphaned sessions, use the PowerShell command “Get-BrokerSession -Hidden $true”
    • To revert all hidden sessions to their visible state, use the PowerShell command “Get-BrokerSession -Hidden $true | Set-BrokerSession -Hidden $false”
