This directory contains various XML descriptors and configuration
files required to run benchmarking experiments using CIAO in
different ways. Let's go over a few important files first:
test.dat:
---------
This file describes the deployment daemons CIAO's Assembly_Manager
will contact to instantiate ComponentServer's, home's, and component
instances. Each line specify the name of a installation
"destination" (I used this to specify <processcollocation>
destination in various *.cad files) and the corresponding IOR for
the CIAO_Daemon. The first entry is the "default" destination the
deployment framework will use.
For example, test.dat now contains:
Default corbaloc:iiop:localhost:10000/ServerActivator
Remote corbaloc:iiop:localhost:12000/ServerActivator
You can copy and modify the copy to deploy the components in various
different locations to let the application truely "distributed".
For example, changing the remote ServerActivator to:
corbaloc:iiop:deuce.doc.wustl.edu:13000/ServerActivator
Remember to start up the Assembly_Manager in Step 2 using the
revised "test.dat" you created, and start up the CIAO_Daemon's in
Step 1 according to the specification.
*.cad:
------
These files specify how an application should be composed. The
specification includes, where to install a component, what
implementation to use, and how to connect components together.
Currently, we have:
Benchmark.cad: Plain vanilla assembly descriptor. This file installs
the RoundTrip component on the location given in test.dat.
RoundTripClient.cad : A descriptor file for the client component
RoundTripClient that uses the interface provided by
RoundTrip.
Test-IOR.cad: This cad file should be used to for testing a CORBA server
with a CIAO client. The IOR of the server should added in
this file.
There are automated perl scripts that can run the tests to generate the
required results. These are located in the individual component directories
Round Trip and RoundTripClient. The descriptors directory has the required
.cad files that specify the component configuration used in the various
experiments.
To run a simple CORBA component with a normal client:
cd descriptors;
../Roundtrip/run_test.pl
cd descritors;
../RoundTripClient/run_test.pl
Script that runs two components one acts as a client and the other as the
server. Statistics are printed for RoundTrip latency jitter etc
cd descritors;
../RoundTripClient/run_test_ior_cad.pl
Script runs a CORBA server and a CIAO component that acts as a client.
Similar statistics are printed.
