First, the concept

Slice:ice provides its own interface definition language. The interface and object used to define the RPC.

The interface called by the Ice.object:rpc must inherit from ice. Object

Servant:ice. The instantiation object of object called Servant,rpc is called the servant object, so servant requires thread safety

Endpoints: Address of client RPC call servant

Containers for Icebox:servant

Containers for Icenode:icebox

Registry: Registry, responsible for the management of Icenode registration, responsibility and release.

II. deployment

Steps:

1. Start Registry

2. Start node, register to registry

3. Deploy code on a node server

4. Apply the app profile to registry, and node will automatically start application

Iii. Configuration Files

Registry configuration file One: registry.cfg

Node config file n: node1.cfg, node2.cfg

Application description File App.xml

Configuration file Details:

Four, start

1. Icegridregistry--ice.config=registry.cfg
   

2. Icegridnode--ice.config=node1.cfg

3. Icegridnode--ice.config=node2.cfg

4. Icegridadmin--ice.config=node1.cfg

   After landing

   Application Add App.xml

Five, the Code

Tomorrow plus ...
