NAME

     pingpongclient — RSerPool Client (PU) for the PingPong service

SYNOPSIS

     pingpongclient [-poolhandle=pool_handle] [-interval=milliseconds]
                    [-cspinterval=milliseconds] [-cspserver=address:port] [-logappend=filename]
                    [-logcolor=on|off] [-logfile=filename] [-loglevel=0-9]

DESCRIPTION

     pingpongclient is a Reliable Server Pooling (RSerPool) pool user (PU) for the PingPong
     service. It is a simple example service for testing RSerPool and its failover
     functionalities.

ARGUMENTS

     The following options are available:

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

     Service Parameters:

             -interval=milliseconds
                     Sets the request interval in milliseconds.

     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.

     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.

ENVIRONMENT

     pingpongclient 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 specified log file.
