Dear All,

   Seems a good utility, but hard to configure. It should be simple as
   Window/Linux update.

   1. Schedule a policy on daily/weekly basis and download the required
   patches/updates from the Symantec website.
   2. Send the notification to System Administrator for the new updates.
   3. Push the new patches from Master/Media server to clients.
   4. Then administrator can decide when he/she want to install the new
   updates/patches.

With Warm Regards

There is a critical step that’s missing from the IIS Web Server setup for
LiveUpdate (and one that took me weeks to get figured out):

You need to add a new MIME type of .flg of type application/octet-stream

I don’t think you need that for Apache, but not sure.

OK, first rule…forget the documentation Symantec gives you for this
process..unfortunately it is not great.  Here is what we use to get http
going for lu for either Windows or Unix.  We have had no problem with it
now that we have the process down..and have been able to patch application
clusters…so not sure what other people have seen there.  Hope this helps:

OK, we usually use http.  The disk share method is for Windows only and
Unix clients can’t get to the patches, which kind of defeats the purpose in
my opinion.  So, we stick with http…here is the process we use:

For unix live update server http access:

      1.      Pull down patches to lu server/dir, unzip all in same dir (no
      subdirs for each patch bundle)
      2.      turn on http on lu server
            /etc/init.d/apache start (first copy
/etc/apache/httpd-example.conf --> httpd.conf)
      3.      ln -s <liveupdate dir> /var/apache/htdocs/<liveupdate dir
      name> or where ever www root is, above is default, this setting can
      be determined from the apach.conf file in /etc/apache/apache.conf
      4.      install nblu on any
            /usr/openv/netbackup/bin/install_nblu
            when prompted type in:
            url=http://<liveupdateserver</<liveupdatedir>
      5.      Create lu policies per normal documentation and go

For windows live update server http access:

      1.      Install IIS, need windows install cd, control panel/add
      remove programs/windows components/application services/IIS (must go
      into details at each level to unselect and select components you want
      for IIS and www)
      2.      Start www service
      3.      Launch IIS manager, highlight default web site, right click,
      new virtual dir.
      4.      Put all patches in wwwroot\liveupdate
      (c:\inetpub\wwwroot\create virtual dir in IIS for liveupdate
      5.      Unzip all in same dir (no subdirs)
      6.      SET LU_SERVER=http://<luserver>/liveupdate  (in
      installdir/symantec/liveupdate/LU_install.bat, then run it, make sure
      you have 3 exe's in there with it, LUCheck, LU_Registration LUSetup,
      all 4 files on NBU windows install cd)

**NOTES:  keep all dir names and servernames lower case for unix/windows

Is anyone using this to upgrade client agents.  All things I've seen/read
are negative about the product.  We wasted many hours trying to get it to
work on version 6.5 when it first came out.  6.5.3 is supposed to fix some
issues, I don't want to go down the LU road again without the possibility
of success!  Anyone have it up and running successfully?

There are many caveats to getting this going properly and some are severe
enough that we're not able to implement it for us for some of the clients.
We had a lengthy discussion with the developers of the client deployment
packages at the last Symantec Tech Day in December so they're aware of the
restrictions.

One of the biggest gotchas for us is that it's pretty much unusable in a
cluster environment.  One of its checks is to see if the client is actually
doing a backup before it tries to upgrade itself.  If you have multiple
names for your hosts - and this is the case for close to 100% of the
cluster users - this check can fail and your backup and/or upgrade job will
fail.

In general, the NetBackup support for cluster clients is pretty poor.
Yeah, Symantec has hacked "support" in there but it's simply the case of
not breaking in a cluster but that's about it.  LiveUpdate is just another
example of where Symantec's cluster "support" fails to solve the problems
properly.
