For a quick introduction to LUA 2.2, I recommend the
Symantec LiveUpdate™ Administrator 2.2 Getting Started Guide. It's on the SEP product CD, or you can download a copy from
http://www.symantec.com/business/support/documentation.jsp?language=english&view=manuals&pid=54619
Full details may be found in the
Symantec LiveUpdate™ Administrator 2.2 User's Guide, which is available from the same location.
Another alternative to consider, if you're designing or administering a pure-SEP environment, is to use SEP's uilt-in GUP (Group Update Provider) capabilities. See
Top 10 Symantec Best Practices - Deploying Symantec Endpoint Protection Architecture for details. If content from a wider range of proucts needs to be downloaded (mixed SAV and SEP environment, plus Scan Engine and SAVfL for instance) then a tool like LUA 2.2 may be best.
Thanks and best regards,
