In a project that is enabled for Rational® ClearQuest®, an activity usually refers to two objects that are linked together: a UCM activity object and a record in a Rational ClearQuest user database whose record type is enabled for UCM. The process of creating an activity in a project that is enabled for Rational ClearQuest entails the creation of two objects in a specific order:
Because the name of the Rational ClearCase activity matches the Rational ClearQuest record's ID, you can access the corresponding activity when you are working on a defect by using the current defect number. For example, you can use the following command: cleartool setactivity ClearQuest-record-ID.
Do not change the name of a Rational ClearCase activity, although it is not prevented. If you change an activity name, you cannot use the setactivity command as described.
Note that the Headline field for a Rational ClearCase activity is synchronized with the corresponding field in a Rational ClearQuest record. That is, if you change this field from within either a Rational ClearCase GUI or Rational ClearQuest, the corresponding field in the Rational ClearQuest record or Rational ClearCase activity is modified as well.
