Upgrading Horizon View Composer to 7.12, How to?


Horizon View Composer server is optional and it is required only if we are planning to use linked clones in the environment.

In previous post, we discussed the Upgrade order, Product interoperability, Database compatibility and upgrade process for Horizon Client. Since we are discussing how to upgrade to Horizon 7.12 release, and I already have linked clones and View Composer in my lab environment, I will have to upgrade the Composer server.

We will discuss View composer upgrade process along with system requirement for View Composer in this post. So to begin with, let’s look at system requirement for View composer server.

View Composer OS Requirements

View Composer can be installed on physical server or virtual machine and it requires 64-bit operating system platform. Supported 64-bit operating system for View composer server are as follows:

Operating System Version Edition 
Windows Server 2008 R2 SP1 64-bit Standard, Enterprise, and Datacenter 
Windows Server 2012 R2 64-bit Standard, Datacenter 
Windows Server 2016 64-bit Standard, Datacenter 
Windows Server 201964-bitStandard, Datacenter

As discussed in previous post, Windows Server 2008 R2 EOS and EOL was on 14th Jan 2020. So you should upgrade to at least Windows Server 2012 R2 operating system. In my lab environment, I am already running View composer 7.7 on Windows server 2012 R2 Standard. So in my setup, I just need to upgrade View composer server to 7.12 release.

View Composer Hardware Requirements

H/W Component Required Recommended 
Processor 1.4 GHz or faster (Intel-64/AMD-64 processor with 2 CPUs )2 GHz or faster, 4 CPUs 
Networking One or more 10/100 Mbps NICs1 Gbps
Memory RAM 4 GB or higher 8 GB or higher RAM if 50 or more remote desktops 
Disk space 40 GB 60 GB

I am already running the required configuration for View Composer Server 7.12 as in image below. That saves some extra efforts on my part. 🙂

Database Requirements for View Composer

View Composer requires an SQL database to store the linked clone related data. Since I am upgrading existing Horizon environment, existing database instance can be used during upgrade process provided that version of database server instance is supported.

In my setup, I am already running SQL Server 2017, so that should be ok to continue.

View Composer installer automatically upgrades the required database schema, so I do not need to perform that manually.

Manually it can be done through command line using sviconfig cmdlet as shown Below

net stop svid
sviconfig -operation=databaseupgrade -dsnname=ViewComposerDB
net start svid

Security-Related Requirements

Well I am using self signed certificates since this is a lab environment. And I am OK with getting certificate warnings too 🙂

Now that we have View Composer server system requirements covered, it is time for the action. I mean upgrade the View Composer server :).


Upgrading View Composer

Thats it. View Composer server 7.7 is upgraded to Horizon View 7.12 successfully.

Now that I have composer server upgraded, next I will need to upgrade my Connection Server that is still running with 7.7 version.

Let’s do that in next post i.e. upgrading Connection Server.
