Option 1:

- Pre-requisites: Please exit out of the FDM application before starting.

  1. Go to the FDM directory folder. The default location for this is C:\Program Files\Grid-Tools\FastDataMasker
  2. Open a command prompt from this window. One way to do this is to type in 'cmd' in front of the file path and hit 'Enter' on your keyboard.

  3. Enter the command java -jar GTMAPPER.exe. This will launch FDM and record debugging information.

  4. Select a database profile and click the 'Connect' button.

  5. With the command prompt still open, recreate the issue you are experiencing.

  6. You should see a stack trace appear in the command prompt.
    This means you successfully enabled debugging.
    If you do not know how to fix the issue after analyzing the stack trace, then please record this information, and send it to support.
    The following steps will tell you how to accomplish this.

  7. At the top of the command prompt window, right-click, select 'Edit' from the list.

  8. Click on the 'Mark' option.

  9. You should be able to highlight the text in the command prompt.
    Select all the text and hit 'Enter' on your keyboard.
    Now the information has been copied to your clipboard.

  10. Paste the text into a program like 'Notepad++'.

  11. Now you can analyze the log file or attach this information to your support case.


Option 2:

  1. Launch FDM.
  2. Connect to a database profile.
  3. Create your masking rules.
  4. In the 'Options' tab, set the 'DIAGLEVEL' to 5. 

  5. In the 'Summary' tab, click the 'Save & Run Mask' button.

  6. Once the masking is complete or errors out, go to your FDM log folder. By default, this is located at C:\%AppData%\Roaming\Grid-Tools\FastDataMasker\Logs.

  7. Now you can analyze the log file or attach this information to your support case.
