RTC中同流内同一模型文件两版本能否自动合并至最新版？

Great question! Let's break down how this works in Rational Team Concert (RTC):

Can You Auto-Merge These Versions? #

Yes, you can perform an automatic merge for these two model file versions in RTC, but success depends on whether there are conflicting changes between version 500 (2018-04-02) and version 590 (2018-04-09).

What You Need to Know #

• Automatic Merge Eligibility: RTC will attempt an auto-merge if the changes in the two versions don't overlap (i.e., no edits to the same model elements). Since version 590 is the newer one, merging the older version (500) into the latest stream will trigger RTC's auto-merge logic first.
• Step-by-Step to Initiate:
  1. Navigate to the model file in your RTC stream repository.
  2. Right-click the file and select the Merge option (or use the "Compare" tool first to preview changes).
  3. Select version 500 as the source to merge into the current latest version (590).
  4. RTC will run a conflict check: if no conflicts are found, it will automatically combine the changes and update the stream with the merged result.
• Conflict Handling: If there are conflicting changes (e.g., both versions modified the same model element), RTC will prompt you to resolve conflicts manually using its merge editor. You'll need to select which changes to retain or combine them as needed.
• Model File Specifics: For structured model files (like UML or EMF-based models), RTC's merge tool is designed to handle structural changes effectively, so auto-merges work smoothly for non-conflicting edits.

Pro Tips #

• Ensure you have the necessary merge permissions for the stream before starting.
• Take a snapshot of the current versions before merging to have a fallback if needed.
• Use the Compare feature first to review changes between versions 500 and 590—this helps you anticipate potential conflicts.
