These products are licensed differently in 32-bit LispWorks for SPARC Solaris and 64-bit LispWorks for SPARC Solaris.
To use each of Delivery, LispWorks ORB, CLIM 2.0 and KnowledgeWorks you must obtain the required key and put in your keyfile. See Keyfiles and the license server on SPARC.
Then you need to load the layered product module. This is done by
(require "delivery") or
(require "corba") or
(require "clim") or
(require "kw"). You could consider configuring an image with the module pre-loaded, by using a
config.lisp file similar to that in Saving a configured image.
