Applying a patch involves uninstalling the current version and then installing the patch version. Not all patch releases include patches for View Composer.

Determine when to perform this procedure. Choose an available desktop maintenance window. Budget 15 minutes to half an hour for each instance of View Composer.

Verify that you have a domain user account with administrative privileges on the hosts that you will use to run the patch installer.

If View Composer is installed in a virtual machine, take a snapshot of the virtual machine.

For instructions on taking snapshots, see the vSphere Client online help.

Back up the vCenter Server database and the View Composer database.

For instructions on performing a database backup, see the documentation from your database vendor.

For all linked-clone desktop pools, disable provisioning of new virtual machines.

If any desktop pools are scheduled to do a refresh or recompose operation, cancel these tasks.

1

On the virtual machine that hosts View Composer, download the installer file for the patch version of View Composer.

Your contact at VMware will provide instructions for this download.

2

Use the Windows Add/Remove Programs utility to remove your previously installed View Composer.

3

Run the installer that you downloaded for the patch release of View Composer.

4

Verify that the VMware View Composer service restarts after the installer wizard closes.

5

If applicable, apply the patch for View Agent on a parent virtual machine and create a desktop pool for testing purposes.

a

Use the Windows Add/Remove Programs utility to remove your previously installed View Agent.

b

Download and run the View Agent patch installer on a parent virtual machine.

Your contact at VMware will provide instructions for this download.

c

Create a small linked-clone desktop pool from this virtual machine.

d

Test a virtual desktop from the desktop pool to verify that all the usage scenarios function properly.

For example, create a desktop pool that contains one virtual desktop, and verify that you can use View Client to log in to that desktop.

Step-by-step instructions for running the View Agent installer and creating desktop pools appear in the Horizon View Administration document, available by clicking the Help button in View Administrator.

e

Verify that virtual desktops from the test desktop pool work as expected.

Apply the patch to View Agent, if applicable.
