Log files from tasks

Log files save the task processing information so you can understand how the task progressed.

Export errors from log file to Excel

The Task Scheduler log files track task errors. Then you can export the errors from the Task Scheduler .mdb file to an Excel file so that they are easier to discover and understand.

The Excel file generates a separate sheet for each error type. The first column of each sheet lists the error files. The second column lists the corresponding task names.

Log file information common to any task type

• In the Operations table:
  • Document Type Indicates the type of Autodesk Inventor LT document being migrated.
  • Document Name Specifies the name of the file that is being migrated.
  • Status Logs status of the operation, and reports if it succeeded or failed.
  • File Location Specifies the file location.
• Task Summary Logs the number of files processed for the current task, and the list of files that failed to process, along with their paths. If you see a failed file name listed, you can quickly copy the path and navigate to the file to investigate the cause of the failure.
• Multiple Processes When you run multiple processes, the log file identifies each process uniquely when starting and closing them. For example:

  Started Inventor1 successfully

  Started Inventor2 successfully

• Start Time Logs the system time when the task was started.
• End Time Logs the system time when the task was completed.
• Error messages common to any task type:

Error message	Recommended Action
Failed to open file using Apprentice Server.	Check the input files and verify that Autodesk Inventor LT can read the format of added files, and run the task again. Before you start the task, open and save the input files in Autodesk Inventor LT.
File does not exist.	Verify that the input files exist in the destination folder just before the task runs. The contents of the folder can change from the time the task was scheduled to the time the task started to run.
File has unresolved references.	Clear the option Skip files with resolved reference in the Migration or Update task before you run the task. Open the input file in Autodesk Inventor LT to set the file references correctly, save the document, and then run the task again.
File is read-only.	Remove the read-only property of input files and run the task again.

Log file information unique to task types

Migrate Files, Update Design

Log interpretation information

• Open Time in seconds (column 5).
• Update Difference between the number of comatose (column 5) and sick (column 6) features before and after the update.
• Rebuild Difference between the number of comatose (column 5) and sick (column 6) features before and after the rebuild all.
• Check Difference in the volume from when it was opened up to the point after the update and rebuild are done (column 5).
• Save Time in seconds and the difference in file size (byte) before and after save (column 6).
• Close Time in seconds (column 5).

Operations results table Operation types lead the rows and operation results lead the columns. The header and footer mention the build number before and after migration:

Operation column Specifies the sequence of the various operations Task Scheduler performs to process the task.

• Open Opens the file in a migrated to version in Autodesk Inventor LT.
• Update Updates the old file to the new Autodesk Inventor LT version. Regenerates only the geometry that has significant edits in memory. These edits could change the file size.
• Check Checks for the mass properties before and after migration of the file.
• Save Saves the file to the migrated version.
• Close Closes the files after migration.
• Purge Deletes the previous versions of the migrated file from the Old Version folder after the migration task ends.

Failures and Recommended Solutions

Operation That Failed	Cause of Failure	Recommended Action
Open	Active security tools or applications.	Disable the security tools and applications and then rerun the task.
	Other applications are running when you begin the task.	Close any applications which could terminate the Autodesk Inventor LT Task Scheduler process, and then run the task again.
	Other unfinished operations are running in Autodesk Inventor LT when you begin the task.	Close Autodesk Inventor LT, verify that there is no Autodesk Inventor LT process footprint left in the Task Manager, and then run the task again.
Update	Autodesk Inventor LT cannot update versions of files older than R6.	Verify that your files are in a version of R6 or later so that they are current enough to be updated.
	Autodesk Inventor LT failed to update the files.	Rebuild the failed files in Autodesk Inventor LT to get more information about the failure. In Migration options, check Total Rebuild, and then run the task again.
Check	Mass properties before and after migration does not match.	Open the files in Autodesk Inventor LT and save them to migrate to the current version or get more information about the error.
Save	Another process is running that can use the files being migrated.	Close all processes that possibly use the added files, and rerun the task.
	Files are set to nonwrite status.	Set write permissions on the files.
	Use Rebuild instead of Update.	In the Migration options dialog box, select the Total Rebuild option, and then run the task again.
Close	Other unfinished operations are running in Autodesk Inventor LT when you begin the task.	Close Autodesk Inventor LT, verify that there is no Autodesk Inventor LT process footprint left in the Task Manager, and then rerun the task.
Purge	Failure.	Purge the Old Versions folder manually after the migration task is finished.
