WebSphere ProfilesWebSphere Profiles

IBM Software Group


Enhanced in v6WebSphere Profiles: What is a Profile

WebSphere Application Server version 6 is split into 2 parts

A set of shared read-only product filesA second set of configurable files

All the configurable WebSphere files are called a Profile and put under a Profile directory

These configurable files include WebSphere configuration, applications, and properties files.

IBM Software Group


Enhanced in v6WebSphere Profiles: Value Add

A Profile allows multiple WebSphere runtime environments share the same product binaries.

WebSphere runtime environments being: Stand-alone NodeManaged NodeDeployment Manager

Less disk space is used (exponential savings the more servers added).

Product update is simplified (update single set of binaries, instead for every server and server configuration)

WebSphere Configuration Archive

Basically the same as a regular WebSphere configuration, with two main differences:

It may be a subset of a full configurationConfiguration information is virtualized to make it portable

Removes any specific information, like the host name

WebSphere Configuration Archives are used to import/export configurations

Allows simple creation of many servers with the same configuration

Enhanced EAREnhanced EAR

IBM Software Group


Enhanced EAR: OverviewAn Enhanced EAR is a zip file that contains a J2EE application (regular EAR) along with deployment information, some application resources (JDBC), and properties (like a class loader), and configuration variables.

Enhanced EAR support integrated with Rational ToolingWebSphere Application Server v6

Benefits: Application resource definitions/properties are brought in with the application Application install process automatically creates the necessary resource definitions within the server or clusterMoving application from one server to another also moves the resource definitions

WebSphere Rapid DeploymentWebSphere Rapid Deployment

IBM Software Group


The Goal - WebSphere Rapid Deployment

To simplify the development experience for WebSphere applications by:

Reducing the number of artifacts Reducing the number of concepts and technologiesSupporting the development model and tools

To simplify the deployment experience for WebSphere applications by:

Automating the process of installing an application on WebSphereReducing the amount of information that must be collected by theinstaller Automating the process of activating incremental changes to an application on a running server

IBM Software Group


Focus Areas – WebSphere Rapid DeploymentAnnotation-based Programming

Allow the developer to create and maintain a single artifactAllow the developer to insert metadata into the source code of the applicationUse the metadata to generate the additional artifacts required by the runtime that the developer does not need to be confronted with

Change Triggered ProcessingDrive processing operations based on the detection of change in artifacts of the applicationUsed to generate new application artifacts from existing artifactsUsed to drive deployment operationsEnables a “Hot Directory” concept for “file copy” and “Notepad” development and deployment

Deployment AutomationEnable automatic installation of applications and modules onto a running WebSphere ServerSupport both local and remote serversSupport fine-grained application changesSupport the concept of minimal application impact (affect the application in the minimum way possible to reflect the detected change)

IBM Software Group


WRD: Annotation-based ProgrammingDeveloper adds metadata tags into application source code

Uses XDoclet tag syntax, where definedWRD uses the metadata to generate additional artifacts needed to run the application on the Application ServerMinimizes number of artifacts a developer needs to create and understand –user maintains the single artifact

Single Java Source File with Annotation-based programming

Multiple Java Source Files and application artifacts

package com.ibm.wrd;/*** @ejb.bean name="Hello" type="Stateless" * view-type=both jndi-name="HelloBean"*/

public class Hello {

/*** @ejb.interface-method view-type=both*/ public String hello(String name){

return "Hello: " + name;}

Platform MessagingPlatform Messaging

IBM Software Group


Platform Messaging

WebSphere Application Server Platform Messaging is a fully-integrated pure-Java messaging environment

Its allows WebSphere Application Server to participate in an implementation of an Enterprise Service Bus

ESB is a conceptual model for SOASIBus is the WebSphere implementation of a single ESB component

JMS support is built on top of platform messaging

IBM Software Group


WebSphere Platform Messaging in v6

Platform messaging fully integrated within WebSphere Application Server

Integrated with WebSphere SecurityCommon install processFully Integrated with WebSphere System Management

Admin Console provides MQ-Explorer type management

All Java implementation within the server process - No external processes

Co-exist with WebSphere MQ

Performance monitoring, Trace and Problem Determination

Workload Management Workload Management –– High AvailabilityHigh Availability

IBM Software Group


Unified Clustering

Management consistency for clustering of different resources

Operational ease of use - The view and use of clusters will be administered in a unified and consistent manner for all protocols (HTTP, EJB, JMS, JCA, etc)

Consistency - New WLM functions (weighted distribution, eWLM integration, SLA, hardware provisioning, etc.) are implemented once for all protocols

High Availability - Makes WLM a highly available service which make cluster and routing information always available

Enhanced Data Replication Services (DRS)

DRS is a mechanism for moving data among WebSphere processes for replication purposes

DRS is used by multiple WebSphere components:HTTP Session memory-to-memory replicationDynamic cache replicationStateful session EJB state replication EJB Persistence manager

Talks to WLM coordinator to align WLM routing with data location

Data Replication Service Enhancements

Integrated with High Availability Manager Improved performance and scalability

Provides a more optimized communication stackAllows for use of both unicast and multicast IPImproves in the range of 4x to 8x

Improves high availability and failure recovery:Leverages the failure detection provided by high availability servicesAlong with the WLM / Unified Clustering integration, this allows for "active failure recovery"– For example, with HttpSession replication, if the affinity server for a HttpSession goes down,

WLM can route to another server that has a backup copy ready to use

Improves usability:Leverages group services to simplify partitioning – Now have "n-replica", where the customer simply defines the number of backup copies they

want for data

Stateful Session Beans state now replicated
