Engine Command

Activity

The Engine Command activity allows you to retrieve statistics and information about process definitions, process instances, and activities in the currently running process engine. This activity also lets you perform engine maintenance, such as suspending and resuming process instances and shutting down the engine.

This activity uses TIBCO Hawk to perform the desired command. A direct call is made to the TIBCO Hawk AMI method (no message is sent).

Note: Before using this activity, the Hawk.Enabled property must be set to either true or local. Also, some commands require memory and processor overhead for gathering statistics or for getting information on the current state of the process. Because of the performance implications, certain instrumentation is disabled by default. You can enable instrumentation for a specific process or for all processes with the Instrumentation property. For more information about setting custom engine properties, see TIBCO ActiveMatrix BusinessWorks™ Administration.
