Oracle SOA Composer detects conflicts that can occur among concurrent users. If you open a domain value map that is being edited by another user, then you see a dialog asking you to confirm whether you want to go ahead with the edit.

If you still want to edit the domain value map, you can click Yes and make the modifications.

If the other user makes changes to the domain value map and commits the changes, you receive a notification message while trying to commit your changes.

If you click Yes and commit your changes, then the changes made by the other user are overwritten by your changes.
