Starting Rational Rhapsody DiffMerge inside Rational Rhapsody

Launching IBM® Rational® Rhapsody® DiffMerge inside IBM Rational Rhapsody is particularly useful if you want to compare one version of an archived unit quickly with another version of the unit inside or outside the archive.
You can quickly compare the two units using Rational Rhapsody DiffMerge inside Rational Rhapsody because you already have Rational Rhapsody and the configuration management system open.

Follow these rules for the units being compared:

About this task

When starting Rational Rhapsody DiffMerge from inside Rational Rhapsody, you can compare two units in either of these environments:

Rational Rhapsody works with any configuration management archive in Microsoft Common Source Code Control (SCC) mode or other tools in batch mode. Rational Rhapsody developers can use any of the following configuration management tools to manage their source files:

Note: For Linux users, you can use batch mode configuration management, and IBM Rational ClearCase.Rational ClearCase is supported in Linux.

Procedure

  1. Be certain that your source control archive is accessible from the computer you are using for this comparison.
  2. Start Rational Rhapsody and open a project.
  3. Verify that the unit you want to compare (for example, a class) is a unit. A Rational Rhapsody element is a unit if a small red file is seen in the lower left corner of its standard icon in the browser, as shown in this Class icon Class icon with small red file in lower left corner indicating that the class is a unit.
  4. If the element is not yet a unit, change it into a unit by right‑clicking the element and selecting Create Unit, and then click OK.
    Note: You must check in any new unit into your configuration management system before it can be recognized by Rational Rhapsody DiffMerge.
  5. Open the Configuration Items window. Choose File > Configuration Items.
    Note: How this window looks depends on your configuration management system.
