NAT42036: 933 Number of steplibs <> number of steplibs on server

What product/components do you use and which version/fix level?

Software AG Designer 10.11, Natural z/OS v825, NDV z/OS v832

Are you using a free trial or a product with a customer license?


What are trying to achieve? Please describe in detail.

When I try stowing an object, using NaturalONE remote mode, sometimes the operatin fails; after waiting a few seconds, I retry the stow operation, and there is success…

Do you get any error messages? Please provide a full error message screenshot and log file.

NAT42036: 933 Number of steplibs <> number of steplibs on server.

Have you installed latest fixes for the products


Please, can anyone tell me what is going on and what must I do?

This is something for the support. I found similar issues.
Check for example whether you have a library twice in the search order, which can be the case if you have the current library also defined as steplib.

Try this:

  1. right-click on the library in Navigator view (not server-view)
  2. Click on properties
  3. click on Natural then Security then Steplibs
  4. click on ‘update steplib definitions’
