DevOps Code ClearCase triggers

When project managers implement project policies with DevOps Code ClearCase® triggers, users may be prompted to provide additional information or take further action with certain DevOps Code ClearCase operations.

A project manager can use ClearCase triggers to control the behavior of DevOps Code ClearCase commands by arranging for a specific program or executable script to run before or after the command runs. Virtually any command that modifies an element can run a trigger.

Although you cannot create a ClearCase trigger from the ClearTeam® Explorer, you might need to respond to a trigger's prompt by supplying additional information or taking further action with certain DevOps Code ClearCase operations.

There are two general categories of ClearCase triggers:

Preoperation triggers fire before the designated ClearCase command is executed. For example, preoperation trigger on checkin can prompt you to add an appropriate comment.
Postoperation triggers fire after a ClearCase operation has completed and can take advantage of the operation's completion status. For example, a postoperation trigger on checkin can send an e-mail message indicating that a particular developer modified a particular element.

Triggers can also automate a variety of process management functions. For example:

Applying attributes or attaching labels to objects when they are modified
Logging information that is not included in the DevOps Code ClearCase event records
Initiating a build or source code analysis whenever particular objects are modified

Note: In some instances, a trigger may perform an operation and you may see not evidence of the trigger firing or performing the operation. In other instances, you may see a display that differs from command to command or from VOB to VOB.
