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.

ARGUMENTS

     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 warnings.

             -logappend=filename
                     Write logging output to a file (default is stdout); output will be appended
                     to given file.

             -logfile=filename
                     Write logging output to a file (default is stdout); given file will be
                     overwritten.

                     Sets the logging verbosity from 0 (none) to 9 (very verbose).
