mkact·ivity [ –c·omment comment | –cfi·le pname | –cq·uery
| –cqe·ach | –nc·omment ] [ –hea·dline headline ]
[ –in stream-selector ] [ –nse·t ] [ –f·orce ] [ activity-selector ...]


The mkactivity command creates an activity. Activities track the work you do in completing a development task. An activity consists of a headline, which describes the task, and a change set, which identifies all versions of elements that are created or modified by work on the activity.

Each stream can have one current activity, which records any changes being made. Use –nset if you do not want to use an activity immediately. To begin recording changes in an activity, issue a setactivity command from a view that is attached to the activity's stream.

Behavior for Projects Enabled for ClearQuest

When executed in a view that is associated with a project enabled for ClearQuest, this command generates an error. The correct way to create an activity is to use the setactivity command, specifying a ClearQuest record ID as the activity-selector.



No special identity required.


An error occurs if one or more of these objects are locked: the project VOB.


(Replicated VOBs only) No mastership restrictions.


Assigning a Headline to an Activity

The activity's name as specified by the activity-selector argument.

–hea·dline headline
Specifies a description of the activity. The headline argument can be a character string of any length. Enclose a headline with special characters in double quotes. The headline is applied to all activities created with this invocation of the command.

Specifying the Stream

The stream attached to the current view.

–in stream-selector
Specifies that the activity be created in this stream.

stream-selector is of the form [stream:]stream-name[@vob-selector], where vob-selector specifies the stream's project VOB.

Setting the Current Activity

If one activity is created with this command: the newly created activity. If more than one activity is created or any number of activities is created outside a view context: none.

Specifies that the new activity not be set as the current activity for the view.

Confirmation Step

Prompts for confirmation of a generated name for the activity if no name is specified by activity-selector.

Suppresses the confirmation step.

Naming the Activity

If one activity is created with this command: a generated name. If more than one activity is created: none.

activity-selector ...
Specifies one or more activities to create.

You can specify an activity as a simple name or as an object selector of the form [activity]:name@vob-selector, where vob-selector specifies a project VOB (see the cleartool reference page). If you specify a simple name and the current directory is not a project VOB, this command assumes that the activity resides in the project VOB associated with the stream attached to the current view. If the current directory is a project VOB, that project VOB is the context for identifying the activity.

The activity name must be unique within the PVOB. All UCM objects share the same namespace. You'll get an error if the name you provide collides with the name of an existing UCM object, for example, a stream.


The UNIX examples in this section are written for use in csh. If you use another shell, you may need to use different quoting and escaping conventions.

The Windows examples that include wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the UNIX shell or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt.
