  1. LSR ObjectWeb/OSMOSE Deployment FrameworkWorkshop in Prague Didier Donsez, Noureddine Belkhatir IMAG/LSR/ADELE

  2. Agenda • Sevilla meeting outcome • Goal • GDF Proposition • Use cases • Model • Personalities • Positioning • Action points

  3. Deployment Working GroupTwo Complementary Approaches • Shared models • MDA PIM • CASE tools • Repositories Personalisation Effort Abstraction Effort J2EE CCM OSGi ProActive Fractal … Descriptors & API Abstraction Effort • Shared code as • tools • libraries • components • frameworks Personalisation Effort From Philippe Merle

  4. 2 levels of interest • Deployment µkernel • Bootstrap core for loading extended functionality • Class Loading • Downloading/Installation/Uninstallation • Application deployment • Potential extended functionality modules • Packaging, Description, Deployment Life Cycle Activities(configuration, dependencies, …), Monitoring, Fault tolerance,Distributed vs Local (1 site), others ??? • Target Platforms • JOnAS JSR88, OpenCCM, OSGi use cases, Fractal • Common deployment tools • Administration console, etc. • Common deployment models • Reference deployment infrastructure architecture • Application deployment models • E.g., ORYA, OMG D&C Framework developeroriented Application deployeroriented

  5. What we have to provide ? • First software deliverable for the 15th of July • Workshop proposition • 27 October in Grenoble • DÉCOR conference (28-29 october) • First return on personalities implementations • Software deliverable v2 for the 15th of December

  6. GDFGeneric Deployment Framework

  7. Motivations • Generic Deployment Framework • Independent to the platform • But Heterogeneous applications (OSGi+J2EE+CCM) • Personalities of this FW • OSGi, J2EE, CCM, Fractal, ProActive, … • Model-based • Application, Site, Process

  8. Which issues are not addressed by GDF ? • Packaging • Platform specific : RPM, Bundle Jarfile, EAR Jarfile • Metadata Formats • Java .MF, RPM multi-files, .NET XML manifest, … • Protocols • Between global and local deployer • rsh, rlogin, ssh, Globus 1,2 …, PBS, LSF, MapRsh • telnet, http, https, soap, xmlrpc, javagroup ?, ip multicast+carrousel … • Should GDF address them ? • The right place (low level GDF)

  14. Model • Unit, DeployedUnit • Application, DeployedApplication • Site, Organization • Dependency / Attributes • Resolver • Process

  15. Model

  16. Attributes & Dependency • Attributes • Set of properties <key,values> • Platform-specific • OSGi: Export-Package, Import-Package, Bundle-Version … • … • Application • Developpement status: beta • … • Dependency • Represents a constraint • Eg: the Unit A requires os=Windows • Eg: the Site B requires stable Units • Eg: the Application C is composed only of signed units by ObjectWeb • Resolved or not by a Attribute

  17. Unit • represents a deployment unit • have attributes • have dependencies • towards unit • Eg: the unit requires the package javax.servlet; version=2.3 • towards sites • Eg: the unit runs only under WindowsXP and more • towards applications • Eg: the unit cannot be use in a commercial application • could embed others units • Eg J2EE EAR = EJBJAR + n WAR + m JAR (of client side applications) • WAR could contain MidLets and Applets • DeployedUnit • represents a deployed unit on a site or in an organization

  18. Application • represents an application • have attributes • have dependencies • towards units • UnitDependency enables to fix the units that compose the application • towards sites • Eg: the unit runs only under WindowsXP and more • Dependencies are added by • the assembler, the deployer, … • DeployedApplication • represents a deployed applicationon a site or in an organization

  19. Site • represents a site on which a part (units) of an application are deployed • have attributes • have dependencies • towards applications • Eg: the application must be stable dev. version • towards units • Eg: the units must be licenced Open Source • Organization • A set of sites

  20. Identity • Platform-specific • OSGi: Bundle-UpdateLocation for Unit • … • One common method • Object getId() • Test equality

  21. UnitRepository • Only an index of available units • Not a storage system (platform-specific) • Units could be loaded from a URL or from a InputStream • In the case of URL loaded, the URL must be one of the attributes of the Unit

  22. ApplicationRepository • TODO

  23. Concrete DependenciesCommon • UnitDependency • LdapFilterDependency • ConjunctionDependency • DisjunctionDependency • NotDependency • FacetDependency • QualifiedFacetDependency • ReceptacleDependency

  24. Concrete Dependencies:OSGi • Unit -> Unit, Application -> Unit • VersionedUnitDependency • ImportPackageDependency (OBR) • Eg: the unit requires the package javax.servlet; version=2.3 • ImportServiceDependency • Eg: A telnet deamon requires a Shell • QualifiedImportServiceDependency • ExportServiceDependency • Eg: A command requires a Shell • ConsumerWireAdminDependency • Eg: Requires consumers consuming temperatures • ProducerWireAdminDependency • Eg: Requires producers producing GPS positions • … • Unit -> Site • NativeDependency

  25. Resolver • Parameters • application dependencies • site dependencies • Select Units in a UnitRepository • According to • application dependencies, • site dependencies, • unit dependencies • And Already deployed units • Return a Process to execute

  26. What is missing • Configuration • Multi-step ? • Pre-installation • Post-Installation (according site attributes) • Manager (OMG D&C) • Actor • …

  27. Interface design issues (i) • Interface Attributes could be replace by • javax.management.DynamicMBean • - muttable interface • + link with JMX and OSMOSE Admin WG • or • org.objectweb.fractal.api.control.AttributeController • - muttable interface • ? Functional or Non functional interface • or • both

  28. Interface design issues (ii) • Attribute values may be java.lang.Comparable • Eg: Version, VersionedPackage, … • Collection parameters and return • Type[] • Iterator • Iterator<Type> JDK 1.5 and + • List/Set • List/Set<Type> JDK 1.5 and +

  29. Interface design issues (iii) • Mutable interfaces • add(Type), remove(Type), … • Observable interfaces • Observes if the Unit A changes its implementation version • get/set Observer • javax.management.NotificationBroadcaster • Finder interfaces • Improve performance during dependency resolution • Dependency can use those indexes to search Attributes objects quickly • Method find(String filter) ApplicationRepository, Organization, … • Others ?

  30. Relationship with other WPs • WP2 • System Management • WP3 • Personalities for J2EE, OSGi, CCM • Personalities for Fractal

  31. Open issues • Code/State migration • ProActive ActiveObject • Positioning / Compliance with • OMG D&C • (Deployment and Configuration of Component-based Distributed Applications) • JSR 88 • (J2EE Server API for 3-tier Deployment Tools) • Others ? • SUN JNLP, DVB-MHP, Linux RPM, …

  32. GDF personalities • OSGi • J2EE • CCM • Fractal • ProActive • DCUP/SOFA • Linux • .NET • Generic • Context Aware, Atonomic, SOA (JINI, WS, OSGi…)

  33. The OSGi personality • First naïve implementation • Reuse Oscar Bunlde Repository metadata • standalone or as a bundle (on site resolver/deployer) • Should merge with ResolveIT ?

  34. Action points • We have a deadline : 15 th of july • Complete the current GDF • OMG D&C subset • or OMG D&C compliance • Share out the work among us • Horizontal (process, resolution, …) • Vertical (platform)
