DESCRIPTION

       rspregistrar provides a registrar service for Reliable Server Pooling (RSerPool) pool elements (PEs)  and
       pool  users (PUs). PRs of an operation scope synchronize their view of the handlespace using the Endpoint
       haNdlespace Redundancy Protocol (ENRP), transported via SCTP. An operation scope  has  a  limited  range,
       e.g.  an  organization  or  only  a  building. In particular, it is restricted to a single administrative
       domain - in contrast to GRID computing - in order  to  keep  the  management  complexity  at  a  minimum.
       Nevertheless, PEs may be distributed globally for their service to survive localized disasters.

       PEs  choose  an arbitrary PR of the operation scope to register into a pool by using the Aggregate Server
       Access Protocol (ASAP), again transported via SCTP.  Upon registration at a PR, the chosen PR becomes the
       Home-PR (PR-H) of the newly registered PE. A PR-H is responsible for monitoring its PEs' availability  by
       keep-alive  messages (to be acknowledged by the PE within a given timeout) and propagates the information
       about its PEs to the other PRs of the operation scope via ENRP updates.

       In order to access the service of a pool given by its PH, a PU requests a PE selection from an  arbitrary
       PR  of  the operation scope, using the Aggregate Server Access Protocol (ASAP), transported via SCTP. The
       PR selects the requested list of PE identities by applying a pool-specific selection  rule,  called  pool
       policy.

       In  order  to allow for automatic configuration, a PR can send out regular announces via an ASAP and ENRP
       multicast address. PEs and PUs can listen to this address to learn the list of currently available PRs.

       The following options are available:

       -quiet  Do not print startup and shutdown messages.

       -announcettl=TTL
               Sets the TTL for outgoing ASAP Announce/ENRP Presence messages via multicast.

       Logging Parameters:
               It is recommended to use at least a value of 2 to  see  possibly  important  error  messages  and
