OOW : Forms 11g – Forms to SOA – Oracle Data Integrator – OFM High Availability

Yesterday a couple of more sessions were on the agenda, which were all very interesting and of course a lot of sneak previews ;o)

Oracle Forms: Strategy and road to SOA
The first session was given by Eurotransplant, a company from the Netherlands that has implemented SOA in its forms-environment in the past few years. During this session Oracle has given an insight on Forms 11g, the road ahead and Eurotransplant gave an insight on the lifecycle they went through.

The most important keynote to keep in mind for Forms 11g is the ability to hook in bpel, human task workflows inside your forms application. The forms application will be event-driven in the future, so the end-users can react upon events through using JMS and Advanced Queueing.

The way Eurotranplant has integrated SOA into their environment was by first giving its Forms-developers a J2EE-development course using the JDeveloper environment and ADF Faces (first they used plain JSP and afterwards UIX), but Faces is the future. By using JHeadstart they could use the automatic generation framework on their existing Forms application.

In 2006 they’ve implemented the first BPEL process and hooked it up inside their forms application. A more advanced bpel process is being implemented right now and will be completed next year. To be able to hook-up bpel processes and service-enable their forms application, they’ve put the business logic which was inside their forms application inside the database. These pl/sql procedures, packages can then e called through pl/sql webservices and integrated inside new bpel processes and their forms applications.

The second session was given by Dave Berry and David Shaffer regarding the new SOA Grid enabled application.
Next generation Grid enabled SOA:

Features:

  • DataGrid Servers: Asynchronous write-behind queues to dehydrate data
  • Grid maintains one instance data of business logic, which can be a service such as bpel process
  • Build new messaging layer that takes advantage of grid-enabled to subscribe to state-changes
  • In memory access feeds (no disk-assistance required)
  • Activate/Rehydrate, relocatable bpel processes
  • Say no to HUB-and-SPOKE
  • Dehydrate current bpel process into grid, and relocate in another grid

SOA GRID:

  • Better performance and availability of bpel processes via SOA GRID
  • Release: 11g , next year
  • ESB Mediation:
  • Primarely stateless against bpel which is primarly statefull
  • Execute async-rule sending rid payload reference id through JMS
  • Subscribe to payloads via reference calls

New Model for Scaling SOA:

  • A new model for efficient resource utilization => scale up horizontally
  • Work together with Coherence for data-usage use cases
  • Use soa-grid inherently for as well cpu, memoiry
  • State-aware continuos availability for service infrastructure
  • Software-only solution, no hardware costs necessary
  • Heterogenous environment

The 3d session that I’ve scheduled today was regarding Oracle Data Integrator, which I’ve blogged about regarding setting up a migration path.

Event-Driven Business Intelligence from Heteregoneous Data using ODI:

The most important message given in this session was: ODI will be integrated in all technology stacks of Oracle, such as BI EE, Oracle SOA Suite

Enterprise Information Management:

Challenges:

  • Understand the past (BI)
  • Coordinate the present (BPM, BAM)
  • Plan for the future

ODI Strategy:

  • Pre-integrated with Oracle Middleware & Applications, BI Tools, Hyperion, Packaged Applications (ERP, CRM), Master Data Management, Fusion Application Pilars

ODI Offering:

  • ODI Core
  • Oracle Data Quality for DI (ODQ)
  • Oracle Data Relationship Management

Differentiator:

  • Declarative design
  • Knowledge modules
  • Active datamodel (change data capture)
  • Batch loads are performed faster via data-caching on staging area
  • Adapters are for free in the whole ODI stack
  • Oracle Data Quality Profiling => changes it into data quality rules

And the last interesting keynote : A Game has been organized during Oracle Open World, to win a plasma screen, car, etc. and this game is using RFID-tags, BAM and ODI as its technology stack. Sadly enough only US citizens can win these prices :(, maybe I’ll need to immigrate to the US before I come to Open World ;o)

The last session for today was very interesting and gave more insight on the different integration efforts oracle is providing throughout its technology stack.

High Availability for Oracle Fusion Middleware:

New Features in OFM 11g:

  • On Demand Scalability
  • Non-stop availability
  • Unified Management: Using the Middleware Administration Server (MAS) and the MAS Repository for configuring changes in one single point of truth, the MAS. The MAS Agent will then push the changes made in the Server to the different OC4J instances existing in your farm.
  • Resource Discovery via MAS: runtime announcement of services, no downtime needed which virtualizes the OC4J connection information
  • OFM Load Balancer: create virtual IP’s
  • Cold Failover Cluster with Oracle Clusterware (CRS), Cluster Manager & Cluster Server
  • High Availability Patching through which you can patch in a sequential manner when you have different Oracle homes or perform out of place patching when you have shared Oracle Homes. Using the Out Of Place Patching you will clone the shared Oracle Home, perform the patches, and merge the cloned Oracle Home with the non-patched version

The most interesting feature and ‘stockhorse’ (stokpaardje) of Oracle: Oracle Coherence which can be described as ‘RAC for the Middletier’.

What are the different features?

  • Distributed Management Solution
  • Runs inside JVMs
  • Automatic ‘scale out’/ horizontal scaling
  • Automatic High Availability : every object in memory has a backup via another server
  • Extreme transaction processing
  • Runs business logic inside the Grid: Analytics
  • Trigger other consumers, applications when data changes in the grid using a push or pull-mechanism

That was it for today, I’ll keep you posted …
