SING A PIPELINE BUILD PROCESS
Novell recommends that certain steps in the virtual application build process be performed on
multiple operating systems in order to ensure maximum compatibility and performance. Because
many of these steps are time-consuming, the process can move more efficiently if the steps are
performed on multiple machines in parallel. This process is referred to as "pipeline building" and
is particularly useful when virtualizing a high volume of apps.
For each application built, Novell highly recommends using three separate snapshot machines in
parallel (Windows XP, Windows Vista, and Windows 7), connected via local network.
The following steps should be performed on each machine in the "pipeline":
7.3.1
Capturing the initial virtual application configuration via snapshot
The snapshot process is covered in detail in the "Snapshotting Applications" topic of the "Getting
Started" section.
The snapshot process should be performed on each machine in the pipeline in order to create the
multiple XAPPL files to be later merged into a single XAPPL file.
Each configuration should be saved in a way that denotes the operating system it was created on
(E.g. <Application><Version>Snapshot_<OS>.xappl), and copied to a network accessible
folder.
The relative paths to files in the folder will be queried when the configurations are merged into a
single XAPPL file. This process- called "platform merge"- can be done on a single machine and is
covered in detail in "Platform Merge" topic in the "Advanced Topics" section.
7.3.2
Profiling the application
The profiling process involves ZENworks Application Virtualization observing normal user
behavior during short virtual application usage sessions, and creating transcripts- or profiles- of
the behavior. The process is covered in detail in the "Creating application streaming models" topic
in the "Advanced Topics" section.
The profiling process occurs after a merged XAPPL file has been created. It should be performed
on each machine in the pipeline in order to create the multiple transcripts that will later be used to
build a streaming model of the virtual application.
Each transcript should be saved in a way that denotes the operating system it was created on (E.g.
<Application><Version>Transcript_<OS>.xt), and copied to a network accessible folder. It is
recommended that multiple profiles are created for each machine in the pipeline (for more
information on building streaming models using transcripts, refer to the "Creating application
streaming models" topic in the "Advanced Topics" section).
