Other Topics of Interest Portal 5.1.03 Portal, March 2006 (we can do POCs now) Portal can be part of same cell as WPS and has WPS ‘underneath’ Worklist Portlets supplied (display and claim and alert) but task processing portlets are written to complete. When Portal is on WPS, then accessing SCA Components can done via SCA Binding, Web Services binding and JMS binding  some configuration required Migration ICS Artifact Migration MQWF Artifact Migration WBISF Artifact Migration WebSphere XD plans WebSphere XD 6.01 and WPS 6.01 will work together On-Demand Router (ODR) -> will handle prioritization and SLA for HTTP and JMS inbound traffic Dynamic Clusters Performance Improvements coming on regular intervals, Scalability is good Accessing J2EE/EJB/Java Multiple ways, non optimal JMS Access Custom (see below)

Patterns Across Products Things that we’re seeing Adaptor + Process Server - almost always have an adaptor or 2 in the mix Broker + Process Server Portal + Process Server Many Modeler  WID/WPS projects, but Modeler still being used by architects in many of these scenarios WAS/J2EE + Process Server - New projects, that might have previously focused on J2EE exclusively, now want to incorporate ‘process’ and thus SOA. Periodic WebSphere Partner Gateway plus Process Server Modeler  WID  RSA Expect more Content Manager + Process Server (we saw a few WBI-SF + CM) Related Realties Lots of J2EE applications that now we want to make services of Limited ‘true’ SOA design skills

Applying the V6.0 Stack to Business Problems Reality is: The ‘no code’ objective is only partially met and in fact, so far we see a few POJOs in almost everything we do. We need the products to work better together with in WBI and across AIM and SWG. We know this and are working on this. Problems we are solving today Business process automation Service creation Integration of existing Assets Production Deployment Enable an SOA Culture to be born, grow and deliver business value Connection to a lot of things Problems we will enable next Event Driven Automatic Service Composition, Selection Complete Business Monitoring of SOA Completely dynamic SLA management Integration of Registry thought at development and runtime Complete Ubiquitous “Connection” Dynamicity and Full support for the lifeCycle of SOA based solutions Problems we are not going to solve (yet) ?

Misc. Information Production Customers coming soon WPS on zOS – June 2006, beta program Clustering works just fine Clustering works just fine XD and WPS work together, more power Things that are challenging us in POCs Bus 3 rd party JMS providers XML/HTTP integration Rules functionality Calling EJBs/Java from BPEL process (likely also a ‘bus’ thing) We’re cataloging ‘where did I have to write code’ versus meeting our goal of solutions without coding

Designing Systems For SOA  What we can enable SOA Observations SOA isn’t a substitute for good design Simple ‘wrappers’ are still ‘simple’ Data, Process and State still matter Good architects, designers and programmers are still needed Good programmers are still needed – hopefully not as many SOA isn’t SOAP, it isn’t just web services and it isn’t just UDDI WSDL and XML (XSD) are the most important ‘notation’ and concepts for SOA Java Services can participate in a SOA in a first class way (via our SCA based approach) WBI 6.0 , built on top of a solid foundation should really : let us get back to first principles let us really get out of the plumbing let us introduce an “integration specialist” role let us leverage the creations of the past effectively in these modern architectures How do we approach this to succeed? How do we approach design? Data Definitions XSD – doc-literal  key to having interfaces that are resilient Requires serious design work to get right Service creation At the edges – abstractions or services where adaptation is needed. These are: Adaptors External web services External systems accessed via JMS/MQ/Messaging Granularity - microflows or Java Components that ‘level’ or ‘right size’ the abstraction layer “ In the middle” – Which tools work the best – reuse models Qualities of service – transparent, but necessary (UOW, security, caching, ..) What are the Key Performance Indicators? What pieces are shared? Amongst? 1 2 3

Process Server Usage Patterns – Early Experience Just Build BPEL Processes – like WBI SF 5.1 Macroflow (and associated patterns) Microflow (and associated patterns) Human Interaction heavy – consider HTM Build integration solutions with key new services and assemble into solutions centered around integration (synchronization, etc..) Use maps, selectors, POJOs to create the ‘glue’ Focus on “Building Services” New business logic view ‘rules’, ‘BPEL’, ‘BSM’ and ‘HTM’ Build those ‘imports’ and ‘exports’ from JMS, Web Services, EJBs, CORBA, CICS, Adaptors in general.. Focus on “Assembling Solutions” Composition New modules where most everything comes from other ‘modules’ Interface Patterns Doc-lit wrappered, Doc-lit, RPC-.. Java Data patterns Where do the XSDs come from: Get your XSDs from Modeler Get your XSDs from 3 rd parties or standards Build your XSDs AsBO/GBO PODO Change summary Event Summary Java Beans Other Reusable ‘interfaces’, ‘maps’, … Heavily Modeler Driven – top down.. Heavy ‘value’, less ‘technology’ focused There are a lot of ways to use this platform. Get started now. This is SOA today. No waiting.

Predefined Tasks and Ad-hoc Tasks Predefined Tasks are tasks that are defined using the Task Execution Language (TEL) They are created using some kind of modeling tool (WID, Notepad, ..) They are either defined standalone or inline in a BPEL process They are deployed as part of an SCA module, using the standard WebSphere deployment mechanisms Ad-hoc Tasks are tasks that are defined at runtime using an ad-hoc task creation API of the Human Task Manager Tasks and Task Templates can be created ad-hoc The meta data used for the ad-hoc creation is specified programmatically Restriction in 6.0.1: If ad-hoc tasks use complex data types then these data types have to be deployed as part of an enterprise application before creating the ad-hoc task using them
