Goals:
------
The goal of this test is to verify that federation of Event Channels
using multicast works correctly. Unlike "Simple" and "Complex" tests,
this test can have any number of Event Channels participating in the
federation, and each participating Event Channel has a full duplex
multicast communication, i.e., both sends and receives events via multicast.
Description:
------------
There are two executables: federation-enabled Event Channel an
application, which acts both as EC consumer and supplier. Any number
of EC/application executable pairs can be started for running the test.
Each application subscribes with its EC for heartbeat events, and,
while listening, also pushes (at regular intervals) 50 heartbeat
events to its EC. Each heartbeat event contains info identifying its
source (hostname + process id). Applications keep track of all the heartbeat
events they receive, and print out the summary before shutting down.
Command-line Options:
---------------------
Application: $application -ORBInitRef Event_Service=<ior> [-d]
where
-d indicates that the application will destroy its Event Channel
before exiting. If each application has its own private Event
Channel, each should use this flag, to have all executables terminate
automatically. If more than one application is using the same
Event Channel, then only one of those applications should use "-d"
option.
Mcast-equipped EC: $gateway_ec -ORBsvcconf <conf_file> -i <ior_file>
where
<ior_file> is the name of the file to which the ior of the Event
Channel will be printed
<conf_file> is a service conf file used to configure the Event Channel
and the multicast components. See consumer-ec.conf or
supplier-ec.conf for examples, or
$TAO_ROOT/orbsvcs/orbsvcs/Event/ECG_Mcast_Gateway.h for
all valid multicast configuration options.
To run:
-------
Automagically (runs three EC/application pairs):
$ run_test.pl
Manually:
As many times as desired (using a different ior file name each time) do
$gateway-ec -ORBsvcconf gateway.conf -i ec.ior
$application -ORBInitRef Event_Service=file://ec.ior -d
