DESCRIPTION

     rspserver is an example Reliable Server Pooling (RSerPool) pool element (PE) that provides
     multiple services. Upon startup, one service has to be selected by the command-line
     parameters. To start multiple services, run multiple instances.  rspserver provides the
     following services:

     CalcApp
             Calculation application model for performance tests. See http://duepublico.uni-
             duisburg-essen.de/servlets/DerivateServlet/Derivate-16326/Dre2006-final.pdf for more
             information.

     CharGen
             Sending as much character data as possible.

     Daytime
             Sending back current time of day.

     Discard
             Discarding incoming data.

     Echo    Echoing back incoming data.

     Fractal
             Fractal generator with cookie-based failover.

     PingPong
             Simple request-response example using cookies for failover.

     Scripting
             Remote execution of scripts with upload/download of input/output data. Could for
             example be used for distributing simulation runs. Take care of security when using
             this service!

ARGUMENTS

The following options are available:

Common Pool Element Parameters:

-local=address:port,address,...
Sets the local endpoint address(es).

-asapannounce=address:port|auto|off
Sets the multicast address and port the ASAP instance listens for ASAP
Server Announces on.

-identifier=PE_identifier
Sets a fixed PE identifier. Handle with care!

-policy=policy_specification
Sets the pool policy and its parameters (default is Round Robin). Supported
policy specifications:

RoundRobin (default policy)

WeightedRoundRobin:weight

Random

WeightedRandom:weight

LeastUsed

LeastUsedDegradation:increment

PriorityLeastUsed:increment

LeastUsedDPF:dpf_value

Priority:priority

...

-poolhandle=pool_handle
Sets the PH to a non-default value; otherwise, the default setting is the
service-specific default.

-quiet Do not print startup and shutdown messages.

-rereginterval=milliseconds
Sets the PE's re-registration interval.

-runtime=seconds
After the configured number of seconds, the service is shut down. Floating-
point values (e.g. 30.125) are possible.

-uptime=seconds
After negative exponential randomized uptime, the PE service goes down for a
configured downtime. After that, it comes up again. This option can be used
for testing the failure handling procedures.

-downtime=seconds
After negative exponential randomized downtime, the PE service comes up
again. This option can be used for testing the failure handling procedures.

Logging Parameters:

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

-logcolor=on|off
Turns ANSI colorization of the logging output on or off.

-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). It is
recommended to use at least a value of 2 to see possibly important error
messages and warnings.

ASAP Protocol Parameters:

-registrar=address:port
Adds a static PR entry into the Registrar Table. It is possible to add
multiple entries.

-registrarannouncetimeout=milliseconds
Sets the timeout for ASAP announces via multicast.

-registrarconnecttimeout=milliseconds
Sets the timeout for ASAP connection establishment.

-registrarconnectmaxtrials=trials
Sets the maximum number of ASAP connection establishment trials.

-registrarrequesttimeout=milliseconds
Sets the timeout for ASAP requests.

-registrarresponsetimeout=milliseconds
Sets the timeout for waiting to receive ASAP responses.

-registrarrequestmaxtrials=trials
Sets the maximum number of ASAP request trials.

Component Status Protocol (CSP) Parameters:

-cspinterval=milliseconds
Sets the interval for the CSP status updates in milliseconds. By default,
the content of the environment variable CSP_INTERVAL is used. If not
defined, no CSP status reports will be sent.

-cspserver=address:port
Sets the address of a CSP monitor server. By default, the content of the
environment variable CSP_SERVER is used. If not defined, no CSP status
reports will be sent.

Service Parameters:

-calcapp
Starts the CalcApp service.

-capcapacity=calculations_per_second
Sets the service capacity in calculations per second.

-capcleanshutdownprobability=probability
Sets the probability for sending state cookies to all sessions
before shutting down.

-capcookiemaxcalculations=calculations
Sets the cookie interval in calculations.

-capcookiemaxtime=seconds
Sets the cookie interval in seconds.

-capkeepalivetransmissioninterval=milliseconds
Sets the keep-alive transmission interval in milliseconds.

-capkeepalivetimeoutinterval=milliseconds
Sets the keep-alive timeout in milliseconds.

-capmaxjobs=max_jobs
Sets the an upper limit for the number of simultaneous CalcApp
requests.

-capobject=name
Sets the object name for scalar hierarchy.

-capscalar=scalar_file
Sets the name of vector scalar file.

-capvector=vector_file
Sets the name of vector output file.

-chargen
Starts the CharGen service.

-chargenmaxthreads=threads
Sets an upper limit for the number of simultaneous CharGen sessions.

-daytime
Starts the Daytime service.

-discard
Starts the Discard service.

-echo Starts the Echo service.

-fractal
Starts the Fractal Generator service.

-fgpcookiemaxpackets=messages
Send cookie after given number of Data messages

-fgpcookiemaxtime=milliseconds
Send cookie after given number of milliseconds.

-fgpfailureafter=messages
After the set number of data packets, the server will terminate the
connection in order to test failovers.

-fgpmaxthreads=threads
Sets an upper limit for the number of simultaneous Fractal Generator
sessions.

-fgptestmode
Generate simple test pattern instead of calculating a fractal
graphics (useful to conserve CPU power when debugging).

-fgptransmittimeout=milliseconds
Sets transmit timeout in milliseconds.

-pingpong
Starts the PingPong service.

-pppfailureafter=messages
After the set number of messages, the server will terminate the
connection in order to test failovers.

-pppmaxthreads=threads
Sets an upper limit for the number of simultaneous PingPong
sessions.

-scripting

-sscachedirectory=directory
Sets the environment cache directory.

-sscachemaxentries=entries
Sets the maximum number of environment cache entries.

-sscachemaxsize=kibibytes
Sets the maximum size of the environment cache in kibibytes.

-sskeepaliveinterval=milliseconds
Sets the keep-alive interval in milliseconds.

-sskeepalivetimeout=milliseconds
Sets the keep-alive timeout in milliseconds.

-sskeeptempdirs

care!

-ssmaxthreads=threads
Sets an upper limit for the number of simultaneous sessions.

-sstransmittimeout=milliseconds
Sets the transmission timeout in milliseconds.

ENVIRONMENT

     rspserver uses the environment variables CSP_SERVER and CSP_INTERVAL to define a CSP server
     to send reports to in the specified interval.
