Pattern Editor pane reference

The Pattern Editor pane contains lists of parts, scripts, and add-ons to graphically work with your topology. You can use these parts, scripts, and add-ons to customize a classic virtual system pattern topology that you can then deploy into your cloud environment.

Parts, scripts, and add-ons

From the toolbar in the Virtual System Patterns pane, after creating or selecting a classic virtual system pattern, click edit to open the Pattern Editor. The Pattern Editor provides lists of available virtual image parts, scripts, and add-ons that you can select and drag onto the editing canvas to customize your selected classic virtual system pattern.

Parts

The Parts list displays the virtual image parts available to use in your classic virtual system pattern. The parts that are available depend on the virtual images installed and the hardware type of any parts already in the classic virtual system pattern. Only parts with the same hardware type as any parts already in the classic virtual system pattern are available. This list might include any number of the following common virtual image parts:

Administrative agents
Core OS
Custom nodes
DB2 servers
Deployment managers
HTTP servers
Job managers
On demand routers
Standalone servers

Hover the cursor over a part label to display additional information about the part and its virtual image. The following actions can be performed:

Drop parts onto the pane from the Parts list.
Edit the properties for the parts on the pane by using the edit properties icon on the part.
Drop scripts or add-ons onto the parts from the Scripts and Add-Ons lists.
Edit parameters, if the script has parameters by using the edit properties icon on the part.
Change the count for some types of parts.
Lock the count.
Delete a part.
Change a part so that it comes from a different virtual image.
Delete scripts or add-ons.

Some virtual image parts represent multiple instances. When you drag the part onto the canvas, you can configure a numerical indicator on the part, so that when the pattern is deployed, multiple instances of the part are generated.

You can configure the properties for the part either when you deploy the classic virtual system pattern or in the Pattern Editor. In the Pattern Editor canvas, click the Properties icon in the part to be configured and configure the properties as needed. Some properties can be locked from further modification by clicking the lock icon next to the property field.

Scripts

The Scripts list displays the script packages that you can drag onto the virtual image parts in the canvas. This list can contain any script packages that are associated with the virtual image and any that you provided for use with Cloud Pak System Software for Power®. You can add script packages to the parts on the editing canvas. Add scripts by dragging them onto the canvas and dropping them onto the part objects.

Script packages can contain license agreements that you must accept before you can include the script package in a virtual system pattern or deploy the virtual system pattern. For more information about accepting license agreements, see the related links.

Add-Ons

The Add-Ons list displays the add-ons that you can add to the parts on the canvas. You can add add-ons to the parts in the canvas by dragging them onto the canvas and dropping them onto the part objects. the following default add-ons are provided with the product:

Default add disk adds a virtual disk to the virtual machine and optionally formats and mounts the disk.
Default add NIC adds one or more network interface controllers to a node for deployment on a virtual machine.
Default add user adds an additional user on the virtual machine.
Default raw disk adds a virtual disk to the virtual machine but does not format or mount the disk.

You can also create and customize additional add-ons to meet your needs and add them to the catalog.

Available views on the canvas

When a classic virtual system pattern is being edited in the Pattern Editor, the graphical topology view is displayed in an editing canvas. You can click either of the following links to view the parts of the classic virtual system pattern in the canvas:

Ordering: This link displays the view showing the order in which the parts are started when the classic virtual system pattern is deployed. If you are working with a copy of a provided classic virtual system pattern, there is a recommended order, and this order is the default setting. In this view, the parts are shown in the canvas and numbered in the order they are started. A text description is also displayed describing the order in which the parts are started, with any order constraints for parts and scripts that might have dependencies.
Topology: This link is available when you are in the Ordering view. Click it to switch back to the default topology view in which the relationship of the parts is shown.

Functions in the toolbar

From either the Topology or Ordering view, you can select from the following icons and links:

Refresh: Forces a refresh of the classic virtual system pattern to ensure that the diagram shows the current state of the classic virtual system pattern on the system. Refresh the classic virtual system pattern if, for example, the classic virtual system pattern was edited by another user since it was last retrieved by the web browser.
Undo: Undo the previous action. The classic virtual system pattern is saved during the editing process, so use this option to revert to the state of the classic virtual system pattern before the previous action.
Undo all: Undo all changes made in the current editing session for this classic virtual system pattern. The classic virtual system pattern is saved during the editing process, so use this option to revert to the state of the classic virtual system pattern before any modifications were made during the current editing session.
Done editing: Indicates that you are done editing and returns to the initial view of the classic virtual system pattern.
Advanced options: This link opens a configuration pane for the classic virtual system pattern you are editing. The configuration pane contains options that are available for this classic virtual system pattern. For more information about configuring advanced options, see the related links.
