7 (Optional) Click the blueprint image to review the highlighted dependencies between services or
application components.
Note all of the dependent components so that you can create an update script if one does not exist or
modify an existing one.
8 From the Node tab, increase the cluster size value for one or more clustered nodes.
9 (Optional) From the Service or Application Component tab, create an update script for all of the
available dependent components with a property bound to the clustered node.
If the UPDATE life cycle stage script are defined, then the scripts appear with the associated service
or application component. If the scripts are not defined, create the applicable script for the update
process.
For example, if a node has the all(node_array:ip) property bound to a clustered node, then it must run
an update script.
10 (Optional) Select the Reboot check box if the agent must restart the virtual machine after the update
script runs successfully and click Next.
The scaled out clustered node and the update tasks of the dependent components appear in the
execution plan. The original execution plan does not appear during an update process.
11 (Optional) Add an APPD_UPDATE_PROPS property in the update script to view a list of all the
changed properties.
The update script is saved in the update profile and can be used for multiple updates. You cannot use
APPD_UPDATE_PROPS as a property name or as a qualifier for a property name.
For example, the sample MySQL service update script includes the APPD_UPDATE_PROPS
property to update the database port and password.
12 (Optional) Add an APPD_PREV property in the update script to view the previous value of a property.
The update script is saved in the update profile and can be used for multiple updates. You cannot use
APPD_PREV as a property name or as a qualifier for a property name.
For example, the sample MySQL service update script includes the APPD_PREV property to view the
value of the database password.

(Optional) Click the Expand Cluster button ( ) to expand the clustered node, select a custom task,
and drag the task to each node.
You can configure the task properties in the Add Custom Task dialog box and save your changes.
14 In the execution plan, review the scaled out clustered node, and update script if applicable and click
Next.
The blue dotted lines in the execution plan define a specific order in which the deployment tasks run.
Click the down arrow next to the service update script to view script details or the variable definitions
used in the script.
