If the metadata system that you are using is AS400/iSeries, you can use the CPYWOWENV command provided in the PJSYS64 folder. This command copies a specified WOW library to a new library and gives you the option to clear the files.
From the CL Command Prompt, enter PJSYS76/CPYWOWENV and press F4.
You should see the following screen:
Enter the source library (in most cases, this would be the default user library [WOWUSER76]). Enter the name of the destination library. Specify whether or not the file data should be cleared or not and press Enter. You have now successfully created an Application Library.
