Horus server

In this context, a Horus server basically refers to a Corba server that provides a HxCorba::Constructor object. The server is addressed via the C language API defined in HxServerCAPI.h.

Corba Horus server

The heart of the server is HxServer. Initialization is done in HxServer::init. The most important steps are:

• Initialize HxDataObjectManager by calling HxDataObjectManager::init
• Initialize the ORB
• Create a POA for the initial objects and create the objects themselves by activating the corresponding servants (in HxServer::addInitialObject). By giving the initial objects also to the Orbacus specific BootManager they are more easily accessible to clients (via corbaloc). The current list of initial objects is:
  • "Constructor" - HxConstructorServant
  • "GlobalOps" - HxGlobalOpsServant
  • "Registry" - HxRegistryServant
  • "Test" - HxTestServant
  • "Configure" - HxConfigureServant
• Set up HxEnvCorba

The server also maintains a list of HxNSBinding's that record bindings of Horus servers in the Corba NamingService.

Stand-alone server application

A stand-alone Horus server is started by the HxServerApp program. The main function is defined in HxCorba/ServerApp/main.c.

Stand-alone Horus server

Command line arguments:

--help

show command line options

--interactive

run the server (ORB) as a background process and provide a command line to execute some commands (see showHelp) to control the server application.

-OAport port

start the server using the given port (default is a random port)

-bind name address:port

bind the server (ORB) under the given name in the NameService at the given address:port combination

For example, to start a Horus server on your local machine at port 8010 use:

hxserverapp -OAport 8010 --interactive

To start a Horus server on your local machine at port 8010 and register it in the Naming Service on machine Mach2 under the name TheServer:

hxserverapp -OAport 8010 --interactive -bind TheServer Mach2:8001

If you start the server with --interactive you can also do the binding at the command prompt of the already running server:

bind TheServer Mach2:8001
