PRs of an opera- tion scope synchronize their view of the handlespace using the Endpoint haNdlespace Redundancy Protocol (ENRP), transported via SCTP. An opera- tion scope has a limited range, e.g. an organization or only a build- ing. In particular, it is restricted to a single administrative domain - in contrast to GRID computing - in order to keep the management com- plexity 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 trans- ported 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 acknowl- edged 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 regu- lar 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. -logcolor=on|off Turns ANSI colorization of the logging output on or off. -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. -loglevel=0-9 Sets the logging verbosity from 0 (none) to 9 (very verbose). Component Status Protocol (CSP) Parameters: -cspinterval=milliseconds Sets the interval for the CSP status updates in mil- liseconds. -cspserver=address:port Sets the CSP monitor server's address and port. Aggregate Server Access Protocol (ASAP) Parameters: -autoclosetimeout=seconds Sets the SCTP autoclose timeout for idle ASAP associa- tions. -asap=auto|address:port,address,... Sets the ASAP endpoint address(es). Use "auto" to auto- matically set it (default). -asapannounce=auto|address:port Sets the multicast address and UDP port to send the ASAP Announces to. Use "auto" to automatically set it (default). Examples: -asapannounce=auto -asapannounce=239.0.0.1:3863 -endpointkeepalivetransmissioninterval=milliseconds Sets the ASAP Endpoint Keep Alive interval. -endpointkeepalivetimeoutinterval=milliseconds Sets the ASAP Endpoint Keep Alive timeout. -maxbadpereports=reports Sets the maximum number of ASAP Endpoint Unreachable reports before removing a PE. -maxincrement=increment Sets the MaxIncrement constant. Handle with care! -maxhresitems=items Sets the MaxHResItems constant. -minaddressscope=loopback|sitelocal|global Sets the minimum address scope acceptable for regis- tered PEs: loopback: Loopback address (only valid on the same node!) site-local: Site-local addresses (e.g. 192.168.1.1, etc.) global: Global addresses -serverannouncecycle=milliseconds Sets the ASAP Announce interval. Endpoint Handlespace Redundancy Protocol (ENRP) Parameters: -enrp=auto|address:port,address,... Sets the ENRP endpoint address(es). Use "auto" to auto- matically set it (default). Examples: -enrp=auto -enrp=1.2.3.4:9901 -enrp=1.2.3.4:9901,[2000::1:2:3],9.8.7.6 -enrpannounce=auto|address:port Sets the multicast address and UDP port to send the ENRP Announces to. Use "auto" to automatically set it (default). Examples: -enrpannounce=auto -enrpannounce=239.0.0.1:9901 -maxelementsperhtrequest=items Sets the maximum number of items per ENRP Handle Table Response. -mentordiscoverytimeout=milliseconds Sets the mentor PR discovery timeout in milliseconds. -peer=address:port Adds a static PR entry into the Peer List. It is possi- ble to add multiple entries. -peerheartbeatcycle=milliseconds Sets the ENRP peer heartbeat interval. -peermaxtimelastheard=milliseconds Sets the ENRP peer max time last heard. -peermaxtimenoresponse=milliseconds Sets the ENRP maximum time without response. -takeoverexpiryinterval=milliseconds Sets the ENRP takeover timeout. ENVIRONMENT rspregistrar uses the environment variables CSP_SERVER and CSP_INTERVAL to define a CSP server to send reports to in the specified interval. DIAGNOSTICS If loglevel>0, log messages will be printed to stdout or into a speci- fied log file.
