To promote the snapshot to an environment, apply the snapshot when you run the
application process.
About this task
In this lesson, you apply a snapshot to your new environment to quickly promote the
components to a new environment. When you request the application process, you select the snapshot
to deploy a selected set of components to an environment.
Procedure
- Open the application page by clicking Applications and then clicking
JPetStore.
- In the same row as your new environment, click the Request Process
icon, as shown in the following figure.
- In the Run Process window, in the Process list,
select the Deploy JPetStore process.
- In the Snapshot list, select the Version 1.1
snapshot.
- Click Submit.
Results
The web page shows you the progress of the application process request, and you can watch as
the processes run. If the process finishes, the request shows that each component process is
finished, as in the following figure:
You can view the running application at the following URL by substituting the host name of
your target system for
hostname. This is the host name of the agent that you
configured in
Configuring the agent and target system. In the URL, specify the
tomcat.contextroot value that you entered for this environment after the port
number.
http://hostname:8081/JPetStoreProd
The application
shows a simple online shopping site in the form of a pet store. The following figure shows the home
page:
If you browse to the Dogs category, you see that the Bichon section is present. As you saw
in the previous tutorial, this entry indicates that the JPetStore-DB component deployed both the 1.0
and 1.1 versions.
What to do next
This application process installed all components in the application by running their
component processes. You defined the versions of the component processes in the snapshot.
You used a snapshot to quickly apply a compatible set of component processes to an
application environment and viewed the deployed web page.
