Alter and drop shared libraries

After you register a user-defined library, you can use the ALTER LIBRARY command to change the library object files, loading option, dependencies, or owner. You cannot change the library name; you must drop the existing library and then create a library with the new name.

You can remove a user-defined shared library by using the DROP LIBRARY command. You cannot drop libraries that are referenced in any existing UDXs. You must resolve those dependencies before you can drop the library, as described in Dependency checks before you drop UDXs.
