Comparing two or three versions of a model in a ClearCase environment

You can compare two or three versions of a model in a ClearCase® environment to view the differences between them.
Attention: To prevent data corruption when you compare or merge models, you must have the appropriate patch for both your IBM® Rational® ClearCase client and server environments. To obtain IBM Rational ClearCase releases and patches, go to http://www.ibm.com/software/awdtools/clearcase/support/index.html.
Note: When you compare three models, one model must be the base model (a common ancestor). The base model must appear higher in the Project Explorer view than the other two versions of the model.
To compare two or three versions of a model in a ClearCase environment:
  1. In the Project Explorer view, right-click a model; then click Team > Show History.
  2. In the ClearCase History Browser window, select two or three model versions.
  3. Right-click the selection; then click Compare Selected Versions.
