You can stop or abort running workflow by one of the following ways:

Issuing stop of abort in the informatica workflow monitor
Issuing stop of abort command in pmcmd.
specifying in the control task.
Stopping or Aborting Task:

When you stop, the integration service first tries to stop processing the task. The integration service does not process other tasks that are in sequence. However it process the tasks that are in parallel to the task on which the stop or abort command is issued. If the Integration Service cannot stop the task, you can try to abort the task. When you abort a task, the Integration Service kills the process on the task.

Stopping or Aborting a Session Task:

When you issue a stop command on a session, the integration service first stops reading the data from the sources. It continues processing and writing data to the targets and then commits the data.

Abort command is handled the same way as the stop command, except that the abort command has timeout period of 60 seconds. If the Integration Service cannot finish processing and committing data within the timeout period, it kills the DTM process and terminates the session.

Difference Between Stop and Abort:

When you run a session, it holds memory blocks in the OS. When issue a abort on the session, it kills the threads and leaves the memory blocks. This causes memory issues in the server and leads to poor performance. Some operating systems clean the lost memory blocks automatically. However most of the operating systems do not clean up these memory blocks. Stop is clean way of killing the sessions and cleans up the memory blocks.
