How to register Ice server with IcePack RegistryH

rc_hzrc_hz Member Eric RCOrganization: www.genband.comProject: No project yet ✭✭✭
I want to use IcePack Registry without IcePack Node, and this is my config file:
%more config.registry
IcePack.Registry.Client.Endpoints=default -p 12000
IcePack.Registry.Server.Endpoints=default -p 12001
IcePack.Registry.Admin.Endpoints=default -p 12002
IcePack.Registry.Data=db
IcePack.Registry.DynamicRegistration=1

First, i start the IcePack registry with the command:
%icepackregistry --Ice.Config=config.registry &

Problem:
1)When the above command is executed, more than one process have been spawned! why ?
%ps -ef | grep icepackregistry | grep -v grep
iceuser 14792 13849 2 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14793 14792 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14794 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14795 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14796 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14797 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14798 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14799 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14800 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14801 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con
iceuser 14802 14793 0 01:25 pts/4 00:00:00 icepackregistry --Ice.Config=con

2)How I white the code to register my Ice server to the Ice registry ? I can neithor find corresponding example nor find API functions about this!

Thanks in advance!

    You not seeing several processes, you are seeing multiple threads within the same process.

    For doc on IcePack, please see the IcePack chapter. Also, the demos in ice/demo/IcePack will help to work out how to set things up.

    Cheers,

    Michi.

    1) I tried again! I can affirmatively say that I am seeing processes not threads!

    2)I have learned examples in ice/demo/IcePack. But they are all relevant to the usage of IcePack Node(automatic-server- activation) and don't demostrate how to register Ice server just using IcePack Registry while not using IcePack Node.

    These are thread, really :) The old Linux threads show up as separate processes.

    Oh....I am wrong! They are theads!

    About the 2nd question: I want to use IcePack Registry without IcePack Node. That is, i want to register my Ice server directly to IcePack Registry and don't want to run a IcePack Node process! How? I can not find anything useful in the "demo/IcePack".

    Run the icepackregistry executable and define the relevant IcePack.Registry.* properties.

    I am sorry to have to disturb you so many times, but i still can not get what you said! This is my test case. What's wrong with me ? Thank you very very much!

    1.In the first window, i run the icepackregistry process:
    iceuser localhost%pwd
    /home/iceuser/work/products/opensource/Ice-1.5.0/demo/IcePack/rctest/registry

    iceuser localhost%more config
    IcePack.Registry.Client.Endpoints=default -p 12000
    IcePack.Registry.Server.Endpoints=default -p 12001
    IcePack.Registry.Admin.Endpoints=default -p 12002
    IcePack.Registry.Internal.Endpoints=default -p 12003
    IcePack.Registry.Data=db

    IcePack.Registry.DynamicRegistration=1
    IcePack.Registry.Trace.ServerRegistry=1
    IcePack.Registry.Trace.AdapterRegistry=1

    Ice.PrintAdapterReady=1

    Ice.ConnectionIdleTime=0

    iceuser localhost%icepackregistry --Ice.Config=config &

    2.In the second window, i run the server process
    iceuser localhost%pwd
    /home/iceuser/work/products/opensource/Ice-1.5.0/demo/IcePack/rctest/hello

    iceuser localhost%more config
    Ice.Default.Locator=IcePack/Locator:tcp -p 12000
    Ice.PrintAdapterReady=1
    IcePack.Registry.DynamicRegistration=1

    Hello.Endpoints=tcp -p 10000:udp -p 10000

    iceuser localhost%server &
    Hello ready

    iceuser localhost%more Hello.ice
    #ifndef HELLO_ICE
    #define HELLO_ICE

    class Hello
    {
    nonmutating void sayHello();
    idempotent void shutdown();
    };

    #endif

    iceuser localhost%more Server.cpp
    #include <Ice/Ice.h>
    #include <HelloI.h>

    using namespace std;

    int
    run(int argc, char* argv[], const Ice::CommunicatorPtr& communicator)
    {
    Ice::ObjectAdapterPtr adapter = communicator->createObjectAdapter("Hello");
    Ice::ObjectPtr object = new HelloI;
    adapter->add(object, Ice::stringToIdentity("hello"));
    adapter->activate();
    communicator->waitForShutdown();
    return EXIT_SUCCESS;
    }

    int
    main(int argc, char* argv[])
    {
    int status;
    Ice::CommunicatorPtr communicator;

    try
    {
    Ice::PropertiesPtr properties = Ice::createProperties(argc, argv);
    properties->load("config");
    communicator = Ice::initializeWithProperties(argc, argv, properties);
    status = run(argc, argv, communicator);
    }
    catch(const Ice::Exception& ex)
    {
    cerr << ex << endl;
    status = EXIT_FAILURE;
    }

    if(communicator)
    {
    try
    {
    communicator->destroy();
    }
    catch(const Ice::Exception& ex)
    {
    cerr << ex << endl;
    status = EXIT_FAILURE;
    }
    }

    return status;
    }


    3.In the third window, i run the icepackadmin process and try the "object find TYPE" command, but i can not find anything:
    iceuser localhost%pwd
    /home/iceuser/work/products/opensource/Ice-1.5.0/demo/Ice/hello
    iceuser localhost%more config
    Ice.Default.Locator=IcePack/Locator:tcp -p 12000
    Ice.PrintAdapterReady=1
    IcePack.Registry.DynamicRegistration=1

    Hello.Endpoints=tcp -p 10000:udp -p 10000

    iceuser localhost%icepackadmin --Ice.Config=config

    An object with the identity "hello" has not been registered with the IcePack registry, therefore the registry returns IcePack::ObjectNotExistException from the query.

    In order for your query to succeed, you would need to invoke the command

    >>> object add "hello:tcp -p 10000:udp -p 10000"

    Or your server could have manually registered its object with the registry by invoking addObject on the IcePack::Admin interface.

    Take care,
