How to withdraw tasks and handle them in Oracle BPM by Jan van Zoggel

clip_image001If you want to withdraw a Human Task in Oracle BPM there are multiple options. This blog post will first show 3 options and then explain how to model your Oracle BPM process to anticipate on the result of a withdrawn task.

1. The BPM Workspace

Using the default Oracle BPM WorkSpace to withdraw a task:

2. Using the TaskService

If you use a custom front-end (instead of the default Oracle BPM Workspace) you can use the Oracle SOA Suite TaskQueryService & TaskService to handle your tasks. In the TaskService there are operations named withdraw and withdrawTasks to either withdraw 1 or multiple tasks. The example below shows a withdrawTask operation request message.

How to customize your Service Bus 12c pipeline templates by Jan van Zoggel

clip_image001One of the new features in Service Bus 12c is the ability to use pipeline templates. Usually the Oracle Service Bus pipelines in an environment have many common steps. Think of the re-use of logging, error handling, alerts and pattern + naming convention for your stages. In practice with OSB 11g we often used a “template” or existing OSB project which we then copied and modified. With the “clone” option of 12c this task is already easier, but the use of pipeline templates is even better. Since templates and concrete pipelines (generated pipelines from a template) remain linked we can update our services easier with new insights. For example, when you want to change your default logging or fault handling behavior.

Index:

To use pipeline templates to their fullest potential we can customize them to our own needs. For this we have multiple options.

Generic configuration

The essential configuration of most actions can be left empty in the template without any problem. As soon as they are implemented in concrete pipelines the actions there will come into an ERROR state. The example below shows the Routing which is empty in the pipeline template. When developing the concrete pipelines we can then easily set the correct business service. Read the complete article here.

Patching your JDeveloper 12.1.3 with SOA Bundle Patch 12.1.3.0.2 by Jan van Zoggel

clip_image001

The SOA(/BPM) Bundle Patch 12.1.3.0.2 is available for download from Oracle Support (http://support.oracle.com)
Just use the search on patch number ‘20423408’ and it will bring you the patch details page with the download (approx. 662MB).
You can deploy the patch on top of your basic 12.1.3.0.0 or the earlier released SOA Bundle Patch 12.1.3.0.1

So I patched my own JDeveloper 12.1.3 environment with the OPATCH tool.
Extract the downloaded patch, I’ll use C:\temp\p20423408_121300_Generic\20423408
This folder is called ‘patch_TOP’ in opatch terminology.

Since I use Windows as local OS you will need to First open a command prompt with Administrator rights (right-click, run as Administrator).
If we don’t use the right permissions we will get the error: Unable to lock Central Inventory. OPatch will attempt to re-lock

First we set our ORACLE_HOME to the Jdeveloper 12.1.3 folder:
SET ORACLE_HOME=C:\ORACLE\middleware\12.1.3
And make sure opatch is in our path:
SET PATH=%PATH%;C:\ORACLE\middleware\12.1.3\OPatch
We browse to the patch_top folder:
cd C:\temp\p20423408_121300_Generic\20423408
And run opatch:
opatch apply

How to use the Domain Value Map (DVM) in Oracle Service Bus 12c by Jan van Zoggel

Introduction

clip_image002Due to the tighter integration of Oracle Service Bus 12c in the whole Oracle SOA Suite product it’s now much easier for developers to use general SOA Suite components like the Domain Value Map (DVM).

Getting Started

First I use the OSB 12c clone project ability to copy th earlier created/blogged OSB 12c Database adapter project and create a project named GetCaseServiceDVM. In the new project we add a Domain Value Map (DVM):

The file name and description speak for themself. The Initial DVM Entries forces us to define the minimum amount of 2 domain names (source and target of our value) and if we want we can inmediately configure the 1st record here.

The result is a DVM file in our project which we can easily edit within JDeveloper 12c.
For this blogpost we will add 2 records which will allow us to translate the value “1” and “2” which we receive from the database to a basic description of that value. Read the complete article here.

Migrating Service Bus 11g to 12c (and the XQuery 1.0 upgrade) by Jan van Zoggel

clip_image001You can easily import an Oracle Service Bus 11g project archive (JAR) in your JDeveloper 12c SB application (File -> Import)

XQuery upgrade:

Howver, when you import your Oracle Service Bus 11g project you will most likely import XQuery transformations as well. When you look at the XQuery editor in JDeveloper 12c you will probably notice that you only have “source” mode and not a graphical editor. Besides that the XQuery files show a “04” icon.

Since the early days of AquaLogic Service Bus the company formerly known as BEA (TCFKAB) supported the W3C working draft of “XQuery 1.0 and XPath 2.0 Functions and Operators” dated 23 July 2004.
In addition TCFKAB supported a number of extension functions easy to recognize with their fn-bea prefix. Since then the world moved on and XQuery made it to version 1.0 in 2007. So now in 12c there is a way to upgrade your XQuery 2004 files to version 1.0. Read the complete article here.

Patching the Oracle Service Bus 12.1.3 unknown protocol deployment error by Jan van Zoggel

If you (already) created your first Oracle Service Bus 12c application/project with SOAP webservices and tried to deploy it to your IntegratedWeblogic server you might be familiar with this error.

clip_image002

Lucky for us Oracle quickly released a solution on their support website and also various blogs picked it up and posted a solution. The earliest reference I found was posted by Link. The solution to your problem was either:

  • Add felix.service.urlhandlers=false to the Init properties of OSGi frameworks bac-svnserver-osgi-framework factory implementation class
  • Remove the default server as a target for the framework

This worked like a charm and I was able to play around with my 12c Service Bus. However since it was stated that the solution could result into problems with BPM on your domain I reminded myself that I wanted to dive deeper into this when I had the time.

Google helped me out, and I discovered this information on the Apache Felix framework website.

Felix installs the URL Handlers service by default. If you do not want this service you can disable it, by setting the felix.service.urlhandlers property to false in the config.properties file. It is not recommended to disable this, but the main reason for doing so it because the URL Handlers implementation invokes methods to set the singleton factories for URL stream and content handler factories. Assuming that you want to use URL Handlers service, you must configure it if you aren’t running on the standard Sun JRE. Read the complete article here.

Using the clone ability to duplicate a Service Bus 12c project by Jan van Zoggel

It’s quite common in a service oriented landscape that a newer version of a service is required. For 01instance due to new functionality for 1 service consumer which brakes the contract for the other consumers.
JDeveloper 12c has a cool feature helping us to clone a Service Bus project. Right-click on the project and select Service Bus -> Clone
Determine the name of your clone target, for instance a version 1.1 of your current project: Read the complete article here.

This blogpost quickly describes the usage of the Oracle SOA Suite 12.1.3 Quick Start Installer for developers.07
After download and extracting the fmw_12.1.3.0.0_soaqs_Disk1_1of1.zip file from the Oracle website you will find 2 JAR files in the archive.

  • 18-06-2014 22:39 2.060.922.907 fmw_12.1.3.0.0_soa_quickstart.jar
  • 18-06-2014 22:38 1.125.261.418 fmw_12.1.3.0.0_soa_quickstart2.jar

Force dehydration in Oracle Business Process Management by Jan van Zoggel

Oracle BPM Catch Timer EventOracle Business Process Management uses transactions to control the steps throughout it’s processes. In the Oracle BPEL processes you are able to use a checkpoint to explicit force a dehydration during your process.

Oracle BPMN doesn’t have a specific activity to perform the same. However you can force a dehydration by using a timer catch event in your process. Setting the timer to 2 seconds is sufficient.

(I think this might actually be 1 second, but the manual claims that the duration should be more than 1 second so we use 2 seconds to be sure).

Oracle Business Process Management Catch Timer Event
Overview of where transactions occur in Oracle BPM/BPEL (source: Oracle performance tuning guide): Read the full article here.
