The system engine performs the information processing and communicates with the database for updating the collected values. It also performs the engine tasks linked to it. It collects the information from the scalability server, processes it, and stores it in the database. The SystemEngine folder and corresponding pane display the tasks the engine is currently running and the task list.
You can also do the following actions:

The following fields are provided in the Task List section:
Lists the names of the current tasks. By default, the system engine runs the following tasks:
Executes the directory synchronization job configured under Control Panel, Directory Integration, Directory Synchronization folder.
Downloads new software signatures from CA Online Content Service to the domain database.
Note: The default software contents download job runs once each day between 12 a.m. and 6 a.m.
Important! Do not run CAF Stop while the software signatures are being downloaded. The download process updates many important tables in the database which needs to be consistent. So, if you kill the process, data can become inconsistent. The download process is a java executable, so check for java.exe in the process list and check that the job ‘Default Software Contents Download Job’ is not running by navigating to the System Engine in the Control Panel.
Executes the default engine collect task configured under Control Panel, Engines, Engine Tasks, Collect Tasks folder.
Processes SCAP checklists located in the ITCM_installpath\SCAP_Checklists folder. If there are new or updated checklists, this job creates a compressed archive of the checklist files, and creates or updates inventory detection modules for the new or updated checklists. By default, this job runs once a day; you can, however, force the engine to run this job when you have added or modified the checklists by clicking the
button in the Engine Task List.
Note: Do not link the default engine tasks to any other engine.
Shows the status of the current task, such as OK, Waiting, and Error. Click the text in the status field to open the Task Status dialog.
Shows the date and time of the latest task execution.
You can take the following actions on a task:
Unlinks the task from the engine. Click the 
button to do this.
Sets the selected task as the next task to be processed by the engine. Click the button to do this.
Informs the engine to process the job again. Click the 
button to do this.
