CA Librarian offers the possibility to use your own name for the Librarian batch and/or Comparator module at your site. This is achieved by applying the User modification MLJ4400 from the Librarian CALJJCL library.
If usermod MLJ4300 for Librarian V4.3 was applied to your previous installation, and the installer gave the AFOLIBR and/or COMP2 module another name, you will need to SMP/E APPLY MLJ4400.
This resolves the need to change all your Librarian batch JCL.
