16.7 Tracking Dynamic Optimization Progress
While running tunevv Dynamic Optimization tasks, you can check the status of each task by
issuing the
showtask command. The output from this command allows you to determine the
following:
■ The start time, completion time, and date of each task.
■ Whether a task has completed or failed.
■ The number of phases (processes) involved for each task, and in what phase a specific task is
running.
■ The number of steps involved for each phase, and on what step a specific task is running.
Issuing the
showtask command displays tasks started within the last 24 hours.
If you wish to view a task or set of tasks that were started more than 24 hours ago, issue the
showtask -t <hours> command, where <hours> specifies the number of hours to trace
back. Refer to the InForm OS Command Line Interface Reference for detailed information
about this command.
■ For more information about running tasks, see Chapter 13, Managing Tasks.
16.7.1 Troubleshooting
When performing a Dynamic Optimization task, errors can occur that can interrupt the task.
Depending on the cause of interruption, you can either rollback or restart a Dynamic
Optimization task.
