In my lab I used the vCenter Server Appliance so I have no choice but to dedicate a separate VM for Composer to run on. For a small environment co-installing it with vCenter is fine, but for a large scale deployment you will want to dedicate a machine for View Composer. View Composer can be installed on the same machine as vCenter or on its own machine. I will be testing Instant Clone in a future post, but want composer to base line my testing against. View Composer is an optional feature, and even less of an option with the new Instant Clone capability of View 7. Linked Clones provide storage savings by sharing a common virtual disk called a replica.

To run the View Composer installer, you must be a user with administrator privileges on the system.View Composer is what allows you to provision and manage Linked Clone virtual machines in your Horizon View environment.

Applications such as Tomcat, which uses Java SSL, or Apache, which uses OpenSSL, are not affected by this constraint. The View Composer installer disables SSLv2 on the Microsoft Schannel.

Verify that no applications that run on the View Composer computer use Windows SSL libraries that require SSL version 2 (SSLv2) provided through the Microsoft Secure Channel (Schannel) security package.

See Configuring TLS Certificates for Horizon 7 Servers.

If you plan to configure an SSL certificate signed by a CA for View Composer during the installation, verify that your certificate is imported in the Windows local computer certificate store.

You enter this information when you install the View Composer service.

Verify that you have the DSN, domain administrator user name, and password that you provided in the ODBC Data Source Administrator wizard.

Verify that you have a license to install and use View Composer.

Verify that no other Horizon 7 component, including Connection Server, security server, Horizon Agent, or Horizon Client, is installed on the machine on which you intend to install View Composer.

Verify that your installation satisfies the View Composer requirements described in View Composer Requirements.
