SOA and E20 Partner Community Forum – 2

Some notes and dump of thoughts on the second day of the SOA and E20 Partner Community Forum. A day filled with interesting breakout sessions. Some of them were discussing roadmaps and future developments in the stack, and thus subjective to an NDA.

SOA platform

Again after this session I came to the conclusion that in my opinion BAM is used too little.

During the session was raised whether people in the audience were using non-Oracle databases as dehydration store and Meta Data Store. The mainstream is using Oracle as dehydration store. And although it is certified, it is advised to use Oracle as the database for this purpose. On the Application Server, given the maturity of the J2EE platform, there is less discomfort in operations to deploy the SOA Suite on a non-Oracle App Server.


Only today I found out that there is an interesting JDeveloper 11g extension. The extension validates ADF code quality. Seems an interesting extension to check code quality besides the already available Java tools.


When comparing BPEL and BPM and looking into when to use what tool, the following was stated: For all things with human interaction BPM is the tool of choice. In integration driven appraoches BPEL is the tool of choice.

In Oracle point of view BPM includes:

  • People
  • Systems
  • Documents

without the need for separate platforms.

Example of a custom Spring Java worklist application for Oracle BPM.

SOA and E20 Partner Community Forum

Today I attended the first day of the SOA and E2.0 Partner Community Forum. For a detailed agenda of the event check this link. The event with 200 registrations was hosted at Capgemini in Utrecht, The Netherlands.

Tattie picking

The first keynote by Andrew Sutherland had a few great stories that leaded the way to show the rationale behind the Exalogic platform. This included a personal story on “tattie picking”. The larger part was on productisation and gave examples on increasing effiency in IT. One of the ways for the Exalogic platform is the one that is also used by Apple: If you limit the amount of hardware your OS of software stack has to be compliant with, that introduces a better controlled and optimized environment; “If you know the machine you need less code”. This is resulting in several efficiencies. Efficiencies both in the One Time Costs (CTB) and Recurring Costs (RTB).

One of the sound bites that stayed with me was:

The most sticky stack is the least sticky one

Indicating that the stack that is the most open and complying with standards is the one that is most likely to survive…

SOA/ BPM Reference Case

In the Partner SOA/ BPM Reference Case Leon Smiers of Capgemini introduced us to the BPM practise of Capgemini and two of their BPM cases. One of the quotes that I think is very true was:

SOA supports the success of BPM.

Besides that Leon stressed the structure, insight and compliance advantages that BPM efforts deliver. One of the things they learned by doing was the importance of showing BAM to business people. This really enables you to get visibility on a lot of stuff that is under the hood. Besides that it is a catalyst for generating more business value with ideas from the people you are showing BAM to.

WebCenter/ UCM Reference Case

During the WebCenter/ UCM Reference Case Vikram Setia of Infomentum shared great insight on how to deliver an excellent web site using Oracle technology. He did this in a very lively session showing us around a live site and telling what Oracle technologies were used behind the scenes. Besides the UCM and WebCenter stuff there were some cool uses database thingies like:

  • Text Clustering
  • Thesaurus
  • Locator

SOA and BPM 11gR1 PS3 Update

Another intresting session was the SOA and BPM 11gR1 PS3 Update by David Shaffer. Mr Shaffer showed us some of the history and some of the highlight in the current stack. A more detailed dive into the latter will be on day 2 of the conference.

Wednesday’s Breakout Sessions

On the second day I will be attending the following breakout sessions:

  • SOA Suite 11g PS3 & OSB
  • ADF/WebCenter 11g integration with BPM Suite 11g
  • BPM 11g, Whats New

Create Data Source in WebLogic Server

While I had to document these steps for a customer that is new to WebLogic Server, I thought why not share these relatively easy steps in a blog post as well. So here they are. The screen shots that come with it are at the bottom.

Create Data Source

  1. Use a browser to go to the WLS Console, for example http://somehost:7001/console/login/LoginForm.jsp
  2. On the home page, click the Data Sources link. You can find it in the Domain Configurations, Services section;
  3. On the Summary of JDBC Data Sources page click the New button (to change current configuration click the link of the Data Sources you want to change);
  4. Choose the Name, JNDI Name, and select the Database Type (Oracle). Click Next to confirm and continue;
  5. Choose the Database Driver. This is depending on the selected Database Type. We used Thin XA for Instance connections for the Data Sources created in the project. Click Next;
  6. Click Next after you read the Transaction Options;
  7. Enter the Connection Properties and after that Next to confirm and continue:
    • Database Name
    • Host Name
    • Port
    • Database User Name
    • Password
  8. Click the Test Connection button, and if the test succeeded click next;
  9. On the Select Targets page check for example the AdminServer. Click finish.

More on configuring JDBC on WebLogic Server can be found here (and the PDF on JDBC admin).

VirtualBox Appliances for Developers

I’m a fan of ready to use appliances for development and demo purposes. Recently it was announced that additional developer Virtual Machines have been released by Oracle. These in addition to the SOA Suite and BPM appliance mentioned before.

Developers can simply download a few files, assemble them with a script , and then import and run the resulting pre-built VM in VirtualBox. This makes starting with these technologies even easier. Each appliance contains some Hands-On-Labs to start learning.

Java Developement

This VirtualBox Appliance contains:

  • Java SE (JDK) 1.6.0 u20 (note: Mac OS X 10.5 users must use Apple update)
  • Java FX 1.3.1 runtime
  • NetBeans IDE 6.9.1
  • GlassFish Server Open Source Edition 3.0.1 (installed with NetBeans)

The Aquarium says about this Java EE6 VM:

This is everything you need to get started with Java EE 6 development and you’ll even find three labs (with code and instructions) to start using JSF 2, JAX-RS 1.1, EJB 3.1, Servlet 3.0, JPA 2.0 and CDI 1.0!

For detailed instructions and downloads go here…

Oracle Database Development

This VirtualBox Appliance contains:

  • Oracle Enterprise Linux 5
  • Oracle Database 11g Release 2 Enterprise Edition
  • Oracle TimesTen In-Memory Database Cache
  • Oracle XML DB
  • Oracle SQL Developer
  • Oracle SQL Developer Data Modeler
  • Oracle Application Express 4.0
  • Oracle JDeveloper
  • Hands-On-Labs (accessed via the Toolbar Menu in Firefox)

For detailed instructions.

It is expected that more flavors will be available in 2011.

Small Oracle Developer Linkdump

Integration of ADF Faces with JavaServer Faces 2.0 is an exciting process that has just begun with the release of Oracle JDeveloper 11g R2 and will continue to be significantly enhanced with the subsequent releases. The aim of ADF Faces is to continue to provide the unparalleled level of functionality and productivity to developers while moving to JSF 2.0. From an ADF Faces framework perspective, most of the changes in adopting JSF 2.0 are internal and should be transparent to developers.

Install OSB next to VirtualBox SOA Suite 11g Appliance

In this post will show you how to install the Oracle Service Bus on the VirtualBox SOA Suite 11g appliance. For this demo we used a pretty straightforward installation scheme.

Oracle WebLogic Server installation

Download wls1033_oepe111150_linux32.bin for installation on Linux. Install using the command ./wls1033_oepe111150_linux32.bin:

Install WebLogic 10.3.3

The following screenshots will give you a good idea of the installation flow.

Oracle Service Bus installation

Start the Disk1/runInstaller.sh and specify the JRE/JDK location /oracle/osbhome/jdk160_18/.

Install Oracle Service Bus

This sequence of screenshots gives you a good impression.

Configure a WebLogic Domain

Configure a Domain using the Oracle Fusion Middleware Configuration Wizard using ./config.sh in the /oracle/osbhome/oracle_common/common/bin directory.
Configuring a WLS Domain
A straightforward configuration of the WLS Domain requires the following steps:

Start WebLogic

./startWebLogic.sh and Have Fun!

Test driving the VirtualBox SOA Suite and BPM 11g Appliance

Few weeks ago I mentioned the VirtualBox SOA Suite and BPM 11g R1 PS2 Appliance. In the last week we’ve been test driving it on several machines.

32-bits Windows7

We noticed that on some 32-bits Windows7 machines the WebLogic Server and SOA Suite fail to start. The reason seems to be that on some 32-bit Windows 7 machines the amount of memory that can be allocated to the VirtualMachine in VirtualBox is limited to 1500 MB.
VirtualBox explains:

The Base Memory sets the amount of RAM that is allocated and given to the VM when it is running. The specified amount of memory will be requested from the host operating system, so it must be available or made available as free memory on the host when attempting to start the VM and will not be available to the host while the VM is running. This is the same setting that was specified in the “New Virtual Machine” wizard.

This can cause a crash when starting the WebLogic Server since the SER_MEM_ARGS are set to:
SER_MEM_ARGS="-Xms512m -Xmx1536m"

These are set in the wls_env.sh which can be found in the /home/oracle/bin/. Altering the -Xmx to a lower value (lower than the amount you can allocate on your workstation) can solve this problem.

Oracle Service Bus

Since I’ve been involved in several projects in the last year that want to use both SOA Suite and the Oracle Service Bus (which at least from some perspectives is part of the SOA Suite) it was a bit disappointing for me that OSB isn’t included. I’ve been asking around for the rationale behind this choice without any satisfying answers so far. Please leave your thoughts in the comments or in this thread of the Oracle forums.
