This test directory tests various demultiplexing strategies used in
TAO for POA, object, and operation name lookups

Description of various files:

CodeGen		Directory containing the code generator

server.cpp	server main program
demux_test_server.{h, cpp}: Server-side implementation details

client.cpp	client main program
demux_test_client.{h, cpp}: Client-side implementation details
demux_test_macros.h: Some constants used by both the client and the server


Generated Files: 
----------------

Must run ./CodeGen/demux tool to generate the following files. See
CodeGen/README for command line options.


demux_test.idl: The Demux_Test IDL interface
demux_test_i.{h, cpp}: Implementation of the Interface
demux_test_client.i: Code to be included with the client
poa_names.dat: Names for all the POAs to be used


Command Line options
--------------------

server -d  (for debugging)
       -p <num POAs>
       -o <num objects>
       -f <IOR file>  default is ior.dat

client -d  (for debugging)
       -p <num POAs>
       -o <num objs>
       -m <num methods>
       -f <IOR file>  default is ior.dat
       -n <loop count>
       -i <invoke strategy> (L = linear
                             R = random
                             B = best w.r.t linear
                             W = worst w.r.t linear)


------
*NOTE* 
------
The num_POAs, num_objs, and num_ops must match on the client
and server side.

Use the svc.conf file and change the -ORBsystemidpolicydemuxstrategy
option to use the desired object lookup strategy. For system ID
policy, active demuxing in the default.

Use the desired options to the TAO_IDL compiler so that it will
generate the right lookup strategy for operation name
demultiplexing.


THE POA LATENCY TEST
--------------------

Make the following changes in Object_Adapter.cpp :

#define ACE_ENABLE_TIMEPROBES

Comment out all ACE_FUNCTION_TIMEPROBE calls except the one 
in  locate_poa  ACE_FUNCTION_TIMEPROBE
(TAO_OBJECT_ADAPTER_FIND_POA_START);


In the demux_test_client : The object loop increments by one.
In gen_names.cpp : 
> Codegen/demux -p 25
> make
> ./server -p 25
> ./client -p 25

The results will reveal themselves !!


THE SERVANT DEMUX TEST :
------------------------

In the demux_test_client : The object loop increments by 5.
