Hp Management Agent; Hp Client Automation Registration And Agent Loading Facility (Ralf) - HP t5400 - Thin Client Quick Reference Manual

HP Management Agent

The HP Management Agent is a software component installed on thin client devices so that HP
Device Manager can interact with them. The agent is embedded in the standard thin client WES 2009
image to enable Device Manager to manage devices out-of-the-box (agents on older devices,
however, may need to be upgraded).
For additional information concerning the HP Device Manager and the HP Management Agent please
check the HP support site for these applications or for other important updates or documentation:

troubleshooting information or Download drivers and software (and firmware). Type the thin
client model in the field and click Enter.
HP Client Automation Registration and Agent Loading
Facility (RALF)
RALF configuration and operation
RALF is shipped pre-installed on the latest HP thin client images (except those running ThinConnect).
It is used to register with an HP Client Automation Server (HPCA) so that the full HPCA agent can be
pushed down and therefore the thin client be managed by the HP Client Automation console. RALF is
configured using a default HPCA Server hostname defined as 'hpcaserver.' While the HPCA server
can be installed to match this name, it is more common to use this name as a DNS alias in defining
the actual HPCA server host name. The HP Client Automation Standard, Starter, and Enterprise
version 7.5 or greater have additional documentation on how RALF can also be re-configured to
define a different hostname using the command line options. More information on HP Client
Automation can be found at see http://www.hp.com/go/easydeploy.
When RALF is installed, it runs as a Windows service or Linux daemon that periodically probes for
the HPCA server. This probing continues for 24 hours, and then RALF will shut down. It starts this
24–hour probe again upon reboot. Once the server is contacted, RALF registers the device with the
HPCA infrastructure and waits to accept the request to install the HPCA agent. Once the HPDA agent
is installed, RALF periodically contacts the server and verifies device registration attributes.
