Best practices for setting up your APP-V sequence machine
When virtualizing applications with Microsoft Application Virtualization (APP-V), one of the steps is application sequencing. With application sequencing the application will be installed in its virtual environment and prepared for streaming delivery. For application sequencing the APP-V sequencer will be used.
Designing and building an APP-V infrastructure is normally just a small piece of your whole application virtualization project. Most of the time will be spent on the sequencing part. To be successful in this step it is important to have your APP-V sequencer configured properly.
The following steps describe how to setup your APP-V sequence machine:
1) Install a clean OS on a virtual machine; make sure you use the same OS level as your corporate desktop image. If you are using a mix of Operating Systems (e.g. Windows 7 and Windows XP), build two sequence stations and use the one with the lowest Operating System version for active sequencing. In some cases it will be necessary to create two sequences for one application.
2) Read the Sequencer Workstation Configuration guidelines in this document and act according these guidelines (also great sequencing guidelines can be found here).
3) Know the “APP-V sequencer vs APP-V client” -supported version matrix.
So, if you’re planning on upgrading to APP-V 4.6, make sure all your clients are upgraded before deploying your applications which are sequenced with the 4.6 APP-V sequencer.
4) Install the APP-V sequencer application; this is a basic setup with no specific configuration options.
5) Configure your defaults. Some settings you can pre-configure, so you don’t have to adjust these settings every time a new sequence is created. Important one is the security descriptor; more info can be found here. To avoid troubleshooting user permissions I disable the “enforce security descriptor” setting by default.
6) Create a snapshot of your installation for fast switching to clean environment.
