Tool Mentor:  Comparing Baselines Using Rational ClearCase

Purpose

Related Rational Unified Process information: Activity: Monitor Project Status

Overview

In ClearCase, a UCM baseline typically represents a stable configuration for a component. A baseline identifies activities and one version of every element visible in one or more components. The ClearCase Component Tree Browser is a GUI that displays the baseline history of a component. You can use it to compare the contents of two baselines. 

This tool mentor is applicable when running Microsoft Windows.

Tool Steps

To compare two baselines in a UCM project: 

1. Start ClearCase Explorer 

To locate the component whose baseline history you want to view, perform this step:

• From the Windows task bar, click Start > Programs > Rational ClearCase > ClearCase Explorer. 

2. Open the Component Tree Browser for a specified component 

• Click Browse Baselines from the component's context menu to start the ClearCase Component Tree Browser.
• Click the Components folder for your project to display a list of components. 
• Right-click on a component to display a context menu. 
• Click Browse Baselines to start the Component Tree Browser.

  See the topic titled ClearCase Component Tree Browser in ClearCase online Help. 

3. Select a baseline and chose comparison parameters

• Select one of the displayed baselines as the basis of the comparison. 
• From the Tools menu, choose one of the Compare… menu item. You are prompted to supply a second baseline to be used in the comparison. 
• You can view differences in terms of activities or in terms of versions. Click the appropriate tab to choose.
