Managing Scripts

From QPR ProcessAnalyzer Wiki
Jump to navigation Jump to search

In QPR ProcessAnalyzer, scripts can be used for ETL tasks and other custom routines. Scripts are managed as part of the Project Workspace.

When a script is running, it's not possible to start another instance of the run, but the first run needs to end before starting another run of the same script. Stil, multiple scripts can run at the same time. Scripts can call other scripts and a called script code can run multiple times simultaneously. In the stack of called scripts, the script log is generated to the top level script. Also the top level script shows are running and the called scripts not.

Scripts List

When selecting a project and opening the Scripts tab, a list of scripts in the project can be seen. Scripts list shows following information:

  • Name: Name of the script.
  • Status: Status of the script, which is one of the following: Ready, Running or Stopping. For more information about script statuses, see below.
  • Last run duration: Duration of the last script run (the last run result can be any).
  • Last run date: Date and time when the last run of the script was started.
  • Last run result: Result of the last run of the script. Either of the following: Completed, Failed or Aborted. For more information about last run results, see below.
  • Id: Id of the script.

Scrips are in either of the following statuses:

  • Ready: Script is not running can be started.
  • Running: Script is currently running. The script can be stopped. Another instance of a run cannot be started.
  • Stopping: Script is currently being stopped. When a script is in this status, the script cannot be started nor stopped, so you need to wait for the script to stop. There may be a delay in stopping a script, depending on the operation currently performed by the script.

The last script run result can be either of the following:

  • Completed: The last run ended successfully, i.e. without any errors or exceptions. Note that despite of the technically successful run, the script might still not work as intended.
  • Failed: The last run ended to an error or exception. To see more information about the reason of the failure, see the last run log.
  • Aborted: The last run was stopped by a user, so the script did not run till the end.
