About the Clipboard tool

Click the icon BYRNB 2/22/10 on the Designer Studio Quick Access area, or type the keyboard shortcut CTRL + B to open the Clipboard tool.

The clipboard has a hierarchical structure based on XML. It resides in memory on the server. As you interact with the Clipboard tool at your workstation, you see a static snapshot copy. Choose Refresh from the Action menu at any time to update the snapshot.

The Clipboard tool displays two panels:

• The left panel displays the page structures, in a hierarchical tree format.
• The right panel displays the value of Single Value, Value List, and Value Group properties and messages, for one page selected in the left panel.

Click the Help button () at the top right for more details on the display.

You can control whether the Clipboard tool opens in a new window or in the lower half of the Developer workspace. C-2268

1. Select Preferences from the Application menu. BYRNB 2/22/10
2. Select or clear the Clipboard box in the Tools group.
3. Click  Save  .

The left panel presents the entire clipboard as a tree, growing from the left.

Two types of pages are grouped for quick access: User Pages and Declare Pages.

Click a name or plus sign () to expand any node in the left panel to view the page structure it contains. Click again or click a minus sign () to collapse (hide) the pages within a page.

If one of the User Pages holds a work object, that page is initially selected in this panel, and details for that page appear in the right panel. PROJ-375

.

When you select a page in the left panel, all Value List, Value Group, and Single Value properties on that page appear in the right panel, sorted by property name. Property messages appear in red text.

Use the left panel to click the page (either top-level or embedded) that contains the property.

Refresh to present current information

As you work, the system creates and updates clipboard pages related to your work. However, these changes are not automatically reflected in the Clipboard tool display. Click Refresh from the Action menu to send the latest clipboard contents to your workstation.

Measuring the size of the clipboard

The Clipboard display shows the contents of the clipboard, but not its size in bytes. Large clipboards can affect performance because memory in the Java Virtual Machine supporting Process Commander holds the clipboards of all requestors.

• You can use the Performance tool to see the size of your clipboard in bytes, or to track the growth and contraction of your clipboard over time. Select > Performance, then click the Add Reading with Clipboard Size link.
• Using the System Management Application (SMA), you can learn the size of each requestor's clipboards, and the size of each page. Start the SMA using > System > Tools > System Management App . Select a node, then click the Requestor Management menu item. 5.5 GRP-372

What properties don't appear?

The Clipboard display includes only a few of the many properties with names that start with pz. Such standard properties support internal operations.

To see pz properties and other clipboard entries that aren't truly properties, right-click in the left panel and select Show XML. To see the contents of unnamed pages, use the Tracer.

The primary pages of some activities are not named and don't appear on the Clipboard display. The parameter page of an activity is not part of the clipboard. Use the Tracer to view these pages.

Properties of mode Java Object, Java Object Group, and Java Object List do not appear on the Clipboard tool display.

The Application page contains much, but not all, of the properties that make up the requestor's application rule. GRP-368

Privileges required

The Clipboard tool is available only to users who have access to the @baseclass.clipboardViewer privilege. Action menu items that update the clipboard contents are available only to users who hold the @baseclass.clipboardViewerUpdate privilege. KHATV 8/17/06

The standard access role PegaRULES:SysAdm4 provides these privileges. KARAF 10/5/04

Several methods manipulate the clipboard. As you execute activities that affect your clipboard, you can examine the results with the Clipboard tool.

For example, when you execute an activity that contains a Page-New method, you can see the resulting named top-level page in the User Pages section. If you execute an activity that uses the Property-Set method (on a named clipboard page), you can see the new values.

The Named Pages gadget summarizes the named pages referenced by the rules in the current application. Select > Data Model > Clipboard Pages > Named Pages to access this gadget.

Installation of a newer JVM version after Process Commander is installed may affect this tool. See Troubleshooting — Developer tools.
