Non-Concurrent Mode

In non-concurrent mode, the Task Manager and Installation Manager run as single processes, and perform the tasks as follows:

The Task Manager handles one task at a time and processes the tasks in a sequential manner based on the priority. The log file for the Task Manager process in non-concurrent mode is TRC_USD_TASKMAN.log.
The Installation Manager alternates between handling notifications and updating the database with the job status from the agent. The log file for the Installation Manager process in non-concurrent mode is TRC_USD_INSTMAN.log.
