  1. OpenCCM: The Open CORBA Components PlatformOSMOSE WP3 CCM Meeting14th November 2003,LIFL, Lille, France Philippe Merle Jacquard ProjectINRIA Futurs – Lille OpenCCM Project Leader

  2. Outline • Objectives • Supported environments • Main features: From design to administration • The open production tool chain • The open packaging and assembling tool chain • The open distributed deployment infrastructure • The open container runtime framework • The open management framework • Perspectives

  3. 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 LGPL • ORB product independent • Flexible, extensible and adaptable frameworks for CCM++ • Become a world-wide used platform for R&D around CORBA component-based middleware and applications • Cadena from Kansas University, …

  4. Supported Environments • OpenCCM = Open CORBA Components Platform • SUN JDK 1.2.1, 1.3.x & 1.4.x • Operating systems • Linux • Solaris • Windows • Windows CE for PDA • ORBs • Borland Enterprise Server (BES) 5.0.2 & 5.2 • JacORB 2.0 • The Community OpenORB 1.2.1, 1.3.0, 1.3.1 & 1.4.0 • ORBacus 4.1.x

  5. Main Features:From Design to Administration • The open production tool chain • Design, define, implement, and compile CORBA components • The open packaging and assembling tool chain • Package and assemble CORBA components • The open distributed deployment infrastructure • Deploy, install, instantiate, and configure CORBA components • The open container runtime framework • Host and execute CORBA components • The open management framework • Discover, introspect, manage, monitor and reconfigure CORBA components

  6. The Open Production Tool Chain • Front-end compilers for • OMG Interface Definition Language 3.0 (OMG IDL) • OMG Persistent State Definition Language (OMG PSS) • OMG Component Implementation Definition Language (OMG CIDL) • UML Profile for CORBA Components • Middle-end repository • Abstract Syntax Tree (AST) • CORBA 3.0.x Interface Repository • Back-end generators for • Client and server equivalent OMG IDL 2.x mapping • CIDL related Java container code • PSDL related Java interfaces and implementations • Java templates for implementing components • OMG IDL 3.0, PSDL, CIDL, and UML pretty-printers • To do • Generation of XML CCD, CSD, and CPF from OMG CIDL

  7. XMI files XMI files XMI UML XMI UML Generator XMI Generators XMI UML files IDL/CIDL files XMI UML files XMI UML IDL/CIDL files OMG IDL/ PSDL/CIDL IDL/PSDL/CIDL Generators IDL/PSDL/CIDL Generators Container code Container code Generators Stubs/skeletons Generators IDL CIDL files IDL CIDL files OMGIDL/ PSDL/CIDL XML Component descriptor XML Component descriptor XML CORBA Component descriptors XML CCD Generator XML CCD Generators Component Implementation Generators Component Implementation Generators Implementation templates Other Front ends Other Front ends Other generators Other Files Other Generators Other files Other files Other Notations Modular and Extensible Production Chain Architecture XMI UML Front end UML OpenCCM Repository OMG IDL/PSDL/CIDL Front end

  8. Example of Use : Cadena = Eclipse Plug-in + OpenCCM

  9. The Open Packaging and Assembling Tool Chain • A stand-one packaging and assembling tool • All CCM XML descriptors and ZIP archives supported

  10. 4 DTD XMLdu CCM 4 DTD XMLdu CCM Data Binding Swing Binding 4 DTD XMLdu CCM CCM XML DTDs ZIP Archives Code XML Plug-in XML Plug-in The Open Packaging and Assembling Tool Chain • A software framework for building customized packaging and assembling tools • Users can build their own P&A tool Apollon + Zeus Browser Framework

  11. 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 infrastructure • IST COACH Distributed Computing Infrastructure (DCI) • As hosted by CCM containers, possible injection ofnon functional properties as persistency, transactions, security, etc. • Transactional distributed deployment • Rollback deployment when failures

  12. COACH Distributed Computing Infrastructure

  13. 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

  19. The Open Container Runtime Framework • Built on top of CORBA 2.4 and provided services • Scripts to start / stop services • CosNaming, CosTrading, and CosTransactions • Runtime library for session components • Set of classes inherited by generated container code • OMG Persistent State Service (PSS) implementation • Built on top of Java Data Object (JDO) • Currently Kodo product • Soon ObjectWeb Speedo • Flexible Container Framework soon • IST COACH Extensible Container Architecture (ECA)

  20. Runtime Architecture DCI Components CORBA Components Observer Philosopher Fork Node Domain Server OpenCCM Flexible Container Framework Plugin Plugin CORBA 2.4 or higher OpenCCM PSS Runtime JDO Runtime Data Stores CosNaming Service CosTrading Service CosTransactions Service CosPersistentState Service

  21. The Open Management Framework • A software framework to build graphical UI management browser • Extensible by plug-ins • Various browser plug-ins for • CORBA Object, Component and Home • Interface Repository • CosNaming • CosTrading • DCI • IST COACH monitoring and testing infrastructure
