BPM Tips

Execution in idle

When a process is initiated by a user interaction (e.g. after record created), it starts to execute in the web server process until the flow reaches a catching event, send message task or user task, that will switch execution to idle mode (process will continue to run by cron/daemon).

If you have script tasks that take some time to run it's reasonable to force to switch execution to idle mode. To avoid the user waiting until scripts are finished. A trick is to add Timer Intermidiate Event with 0 timer value. You can add it right after a start event.

Unsetting process variables

All variables defined in script task will be stored in the process. If you don't need a specific variable to be used further in the process, it's reasonable to unset it in the end of the script.

$tempVariable = null;
