Deployment Working Group Two Complementary Approaches Abstraction Effort Descriptors & API J 2 EE Abstraction Effort CCM Shared models • MDA PIM • CASE tools • Repositories OSGi Pro. Active Shared code as • tools • libraries • components • frameworks Personalisation Effort Fractal … Personalisation Effort From Philippe Merle 3

Motivations q Generic Deployment Framework q Independent to the platform q q Personalities of this FW q q Mixin of platform (OSGi+J 2 EE+CCM) OSGi, J 2 EE, CCM, Fractal, Pro. Active Model-based q Application, Site, Process 4

Model 11

Attributes & Dependency n Attributes n Set of properties <key, values> n Platform-specific n n n Application n OSGi: Export-Package, Import-Package, Bundle-Version … … Developpement status: beta … Dependency n Represents a constraint n n 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 Object. Web Resolved or not by a Attribute 12

Unit n n n represents a deployment unit have attributes have dependencies n towards unit n n towards sites n n Eg: the unit cannot be use in a commercial application could embed others units n n n Eg: the unit runs only under Windows. XP and more towards applications n n Eg: the unit requires the package javax. servlet; version=2. 3 Eg J 2 EE EAR = EJBJAR + n WAR + m JAR (of client side applications) WAR could contain Mid. Lets and Applets Deployed. Unit n represents a deployed unit on a site or in an organization 13

Application n represents an application have attributes have dependencies n towards units n n towards sites n n Eg: the unit runs only under Windows. XP and more Dependencies are added by n n Unit. Dependency enables to fix the units that compose the application the assembler, the deployer, … Deployed. Application n represents a deployed application on a site or in an organization 14

Site n n n represents a site on which a part (units) of an application are deployed have attributes have dependencies n towards applications n n towards units n n Eg: the application must be stable dev. version Eg: the units must be licenced Open Source Organization n A set of sites 15

Identity n Platform-specific n n n OSGi: Bundle-Update. Location for Unit … One common method n n Object get. Id() Test equality 16

Unit. Repository n n Only an index of available units Not a storage system (platform-specific) n n Units could be loaded from a URL or from a Input. Stream In the case of URL loaded, the URL must be one of the attributes of the Unit 17

Application. Repository n TODO 18

Concrete Dependencies Common n n Unit. Dependency Ldap. Filter. Dependency Conjunction. Dependency Disjunction. Dependency 19

Concrete Dependencies: OSGi n n n Versioned. Unit. Dependency Import. Package. Dependency (OBR) n Eg: the unit requires the package javax. servlet; version=2. 3 Import. Service. Dependency n n n Service. Binder. Import. Service. Dependency Export. Service. Dependency n n Eg: Requires consumers consuming temperatures Producer. Wire. Admin. Dependency n n Eg: A command requires a Shell Consumer. Wire. Admin. Dependency n n Eg: A telnet deamon requires a Shell Eg: Requires producers producing GPS positions … 20

Resolution n n The units are the root of a multi-colored graph Edges are satisfing dependencies One color per type of dependency A deployment is succeful if all dependencies are satisfied n For the application, sites and units 21

Resolution (TODO) n An application Unit. Dependency id=1 Unit. Dependency id=2 Unit. Dependency id=4 Unit. Dependency id=3 22

Algorithm (TODO) 23

Interface design issues (i) n Interface Attributes could be replace by n javax. management. Dynamic. MBean n org. objectweb. fractal. api. control. Attribute. Controlle r n n n - muttable interface + link with JMX and OSMOSE Admin WG - muttable interface ? Functional or Non functional interface or n both 24

Interface design issues (ii) n Attribute values may be java. lang. Comparable n n Eg: Version, Versioned. Package, … Collection parameters and return n n Type[] Iterator<Type> JDK 1. 5 and + List/Set<Type> JDK 1. 5 and + 25

Interface design issues (iii) n Mutable interfaces n n add(Type), remove(Type), … Observable interfaces n n get/set Observer javax. management. Notification. Broadcaster Finder interfaces n n Improve performance during dependency resolution Dependency can use those indexes to search Attributes objects quickly n n Observes if the Unit A changes its implementation version Method find(String filter) Application. Repository, Organization, … Others ? 26

Relationship with other WPs n WP 2 n n System Management WP 3 n n Personalities for J 2 EE, OSGi, CCM Personalities for Fractal 27

Open issues n Code/State migration n n Pro. Active. Object Compliance with n OMG D&C n n JSR 88 n n (Deployment and Configuration of Component-based Distributed Applications) (J 2 EE Server API for 3 -tier Deployment Tools) Others ? n SUN JNLP, DVB-MHP, Linux RPM, … 28

Which issues are not addressed by GDF ? n Packaging n n Metadata Format n n Platform specific : RPM, Bundle Jarfile, EAR Jarfile Java. MF, RPM multi-files, . NET XML manifest, … Protocols n Between global and local deployer n n n rsh, rlogin, ssh, Globus 1, 2 …, PBS, LSF, Map. Rsh telnet, https, soap, xmlrpc, javagroup ? , ip multicast+carrousel … Should GDF address them ? n The right place (low level GDF) 29
