Perspectives


Objectives

Become the reference implementation of the OMG CORBA Components specification

To design, define, implement, compile, package, assemble, deploy, install, instantiate, configure, execute, discover, introspect, manage, and reconfigure distributed CORBA component-based applications

Provide an Open CORBA Components platform Open source licensed under LGPLORB product independentFlexible, extensible and adaptable frameworks for CCM++

Become a world-wide used platform for R&D around CORBA component-based middleware and applications

The Open Distributed Deployment Infrastructure

All CCM XML descriptors and ZIP archives supported

CosNaming, CosTrading, and HomeFinder services supported

All Components::Deployment API supported

Component-based deployment infrastructureIST COACH Distributed Computing Infrastructure (DCI)

As hosted by CCM containers, possible injection of non functional properties as persistency, transactions, security, etc.

Transactional distributed deployment

Rollback deployment when failures

OpenCCM DCI Components

DCIManager = a deployment domain Provides AssemblyFactory and HomeFinder

NodeManager = a virtual host Provides ComponentInstallation and ServerActivator

ComponentServerManager = a component server Provides ComponentServer

ContainerManager = a container Provides Container

AssemblyManager = an assembly deployment controller Provides Assembly

Each component provides other ports for management and supervision purposes
