• Operation
  • Modify the parameter monitor_file_change_location of order1 to point to a file in your environment.
  • Start order1 from the JOC user interface.
    • Immediately modify and save the monitored file. Changes of the file size are checked every 10s for a max. duration of 30s.
    • After 30 seconds order1 will either be successfully moved to job2 or it will fail depending on the monitored file being considered steady within the given timeout.

Implementation

Configuration

• The File Size Monitor can be configured from job or order parameters.

• The following parameters are used:

  Parameter	Required	Default	Description
  monitor_file_change_location	yes		The full path of a file that should be monitored.
  monitor_file_change_timeout	yes		The max. duration in seconds that repeated checks for steady file size are performed.
  monitor_file_change_interval	no	1	Specifies the number of seconds that the monitor sleeps between repeated checks of the file size.
  monitor_file_change_exit_code	no	1	Optionally sets the exit code of the current job to the specified value if the monitored files is not being found steady. This works for shell jobs exclusively.
  monitor_file_change_error_state	no		Optionally sets the order to the specified state if the monitored file is not being found steady

Implementation

Order Implementation

• An order can be used to carry the parameters for the File Size Monitor.

• The order can be implemented like this:

  Code Block
  language xml title Order Implementation Sample linenumbers true collapse true
  <order> <params > <param name="monitor_file_change_location" value="/tmp/jobscheduler/file/some_changing_file.txt"/> <param name="monitor_file_change_timeout" value="30"/> <param name="monitor_file_change_error_state" value="error"/> </params> <run_time /> </order>
