Flex fields Mapping Tool by BPM SOA Solutions Team

January 22, 2017 Leave a comment

How many times have you had to repeat the same sequence in the BPM workspace to map a Human Task payload attribute to a public Flex Field? Let’s do a bit of re-cap:

login to the Workspace with administration permissions
go do Administration
go to Public Flex Fields
create all Labels

And then, for each human task:

search for the task
choose the payload attribute
search for the label to use (you can create them here as well)
repeat until you’ve mapped all the labels you need
save and move to the next

It seems like a lot of work to do and it is fair to say that our platform team was not very happy to do these tasks manually. Even when developing these mappings need to be re-created from time to time (more often than we wished). The whole process is furthermore error-prone, specially when moving from development to QA and to Production environments.

Automating the creation and mapping of labels and payload atributes

Oracle BPM/SOA 11g and 12c expose an API for managing labels and mapping them as required. The oracle.bpel.services.workflow.runtimeconfig.IRuntimeConfigService interface provides a series of methods for creating and deleting labels, as well as creating oracle.bpel.services.workflow.runtimeconfig.model.PayloadMapping instances to map a label to a payload attribute.

Unable to compile a composite that contains a Java embedded activity with Maven by Markus Lohn

January 21, 2017 Leave a comment

Problem

Maven is not compiling the composite when a BPEL process contains java embedding. Just incorporating java embedding makes the maven compilation to fail. If the java embedding is removed then the composite compilation is successful in Maven. This issue can be reproduced with JDeveloper 12.1.3.x

Research

First I tried to solve this issue by adding dependency declarations for orabpel.jar in the soa maven plugin section and the pom.xml itself. However this approach doesn’t solve my issue. After another research in the Oracle Support system I found two interesting notes:

Unable to compile a composite that contains a Java embedded activity with Maven (2050971.1)
Failure when compiling a BPEL process in SOA 12c, ‚package com.collaxa.cube does not exist’ (2112178.1)

Both notes describe exactly the issue I currently have. The note 2050971.1 contains a reference to the bug no. 20229616 wherefore no patch is available until now. But it contains a description for a workaround. The workarounds means to put every needed Java library in the folder SOA/SCA-INF/lib. From my perspective that isn’t an appropriate solution, because the missing classes mention by the compiler are in orabpel.jar. This jar file is part of SOA Suite and already available on the infrastructure side. Moreover everything in /SCA-INF/lib is part of the composite and uploaded to MDS. The second support note 2112178.1 references a patch, but it doesn’t also solve the issue. Due to this I build a solution that automates the workaround with SOA/SCA-INF/lib by using Maven plugins.

Solution

The solutions contains 3 steps:

1. Using the Maven Dependency Plugin to copy the orabpel.jar to SOA/SCA-INF/lib folder. The copied orabpel.jar will be renamed to only4compile.jar. Further it is important to bind the execution of the plugin to a phase before running the Maven SOA Plugin. Read the complete article here.

Process Cloud Service: new features! By Lykle Thijssen

January 18, 2017 Leave a comment

During Oracle Open World 2016, the latest release of Oracle Process Cloud Service got presented. The product has been making huge progress in all aspects, so here’s an overview of all the new and improved features.

Oracle Process Cloud Service

For those of you unfamiliar with the product: Oracle Process Cloud Service (PCS) is Oracle’s BPM solution for the cloud. While development on Oracle BPM Suite has pretty much come to an end, Oracle Process Cloud Service is the way forward and the platform for all new features related to Business Process Management. This meant that the product that was originally positioned as BPM for the citizen developer had to improve and mature to a full-blown BPM solution. It needs to support long running processes, improve its integration strategy and support case management, to mention some important subjects. While case management is not there yet, it will certainly come to Oracle Process Cloud Service and many other features are already there with the latest release.

Modelling Processes

As it used to be, modelling processes is done in the browser. This makes it easy for business and IT to collaborate on processes, because you only need an internet connection to get access. No need for development tools, code repositories and a powerful work station to get started. The main improvement in the process modelling is that Oracle has abandoned the usage of Flash. This makes the process modeller faster and easier to use, creating a far more pleasant and performant development experience.

Selecting integrations

When creating a Service Call, whether it’s synchronous or asynchronous, you can now select an Integration from Oracle Integration Cloud Service. Obviously, this is much more practical than dealing with WSDL imports and all the technical stuff related to that, but it also has a bigger meaning. It’s clearly showing that Integration Cloud Service has been strategically positioned as the way to go for process integrations. It’s putting the technical know-how of integration where it belongs, so you will no longer feel tempted to take that kind of complexity into a business process. Therefore, I strongly recommend following this approach as suggested by Oracle, instead of trying to work out your own integrations in PCS. Use these products for their purpose.

What those extra Healthcare flags on Oracle SOA 12.1.3.0.5 and 12.2.1 update are for? by Bruno Neves Alves

January 15, 2017 Leave a comment

Whilst upgrading to 12.1.3.05 I came across the following Post Installation actions at the READ.ME doc of the 22524811 patch:
"4 Post-Installation Instructions"
2. Add em property : hc.jmsAndDBSameTxn with ‘true’ value.
3. Following Healthcare Server properties are needed:
        – hc.sequencedEndpoints
                + ALL,<EP_1>,<EP_2> – comman separate value
                + Any endpoints after ALL will not be sequenced.
                + In this example, <EP_1> will have sequcing turned off. <EP_2> will have sequencing turned off.
Note for Bug 20029769:
hc.HCMode (true/false, default false) – need to set to true
At the customer, we intended to promote the upgrade to the actual production environment and, because of this, it required further validation of the impacts of such upgrade could bring.
Since the description was not clear enough and I could not find information anywhere else, I raised a service request at Oracle Support for further clarification.
First, I would like to thanks Silviu from Oracle Support for his help and support he have been providing me for the last few years 🙂
And here are the conclusions of the service request and clarification of the new flags usage:
hc.jmsAndDBSameTxn - if true, committing to the JMS for customer JMS will be on the same transaction as database. If database is rolled back, then the message will not be committed to JMS as well. (I’m waiting additional clarification for this point and will add it here once I have it). Read the complete article here.

SOA Messaging Reliability through JMS and Oracle Service Bus by Sebastian Lik-Keung Ma

January 14, 2017 Leave a comment

This article describes the design of a reliable messaging solution for SOA integration projects. It uses concepts like canonical schemas, durable POJO (Plain Old Java Object) messages, publish-subscribe and error handling within the Oracle SOA, Oracle Service Bus and WebLogic JMS infrastructure.

The JMS Message

For consistency, the type of message we are publishing will be based on a canonical schema. Typically, you would have a JDeveloper project that stores the canonical schemas used by all your custom applications. These schemas could be version-controlled, e.g. by Subversion, as well as deployed to MDS as a SOA bundle. Sample JDeveloper project containing canonical schemas shown below.

In this article, we will use the employeeWorkSchedule schema as our message type.

Publishing JMS message from ADF Java application

We publish our message to JMS from ADF applications. To simplify the process of using Java to construct message objects based on our XSD canonical schema, we use the JAXB (Java Architecture for XML Binding) tool from JDeveloper.

As shown in Figure 2a below, select the XSD file, right-click and select “Generate JAXB 2.0 Content Model”. Read the complete article here.

WS-Addressing callback interception using Service Bus by Jeroen Ninck

January 12, 2017 Leave a comment

Maarten Smeets posted a nice article describing asynchronous interaction in BPEL and BPM using WS-Addressing and correlation sets. I wanted to use Service Bus 12c to force the callback to go through a Service Bus proxy instead of going directly to the consumer. This can be useful when the target service should not have the ability to call services outsite of its trusted domain or network.

All sources can be found in my GitHub repository.

WS-Addressing

WS-Addressing provides a way for message routing and correlation using SOAP headers. It is an official specification. Service Bus, SOA Suite, JAX-WS and quite a lot of other frameworks and tools support it one way or the other. There are two versions of WS-Addressing: 200508 and 200408.

In an synchronous interaction the following headers are important:

Request:
- ReplyTo
- MessageId
Callback:
- RelatesTo

In the request the ReplyTo specifies the address where the reply must be send to (or http://www.w3.org/2005/08/addressing/anonymous if no reply address is specified). The MessageId headers contains a unique id which can be used to to correlate the request to a future callback. In the callback the RelatesTo header contains the original MessageId. There are others headers for example Action which are important, but for creating an asynchronous interaction ReplyTo, MessageId and RelatesTo are all that are required.

SOA Suite 11g and 12c support WS-Addressing (don’t mention SOA Suite 10g…) and provide out of the box correlation support. Using BPEL no code is required to use WS-Addressing for correlation (both as consumer and as producer).

Test scenario

A SOA composite will implement an asynchronous webservice (a fire & forget request followed by a future fire & forget callback). It will be exposed using a Service Bus project which will ‘hide’ the implementation for the outside world. For example the SOA composite might be running in a local domain, while the Service Bus project migt be running in a SOA CS cloud instance. This will allow to SOA composite to only receive traffic from ‘trusted’ networks and the Service Bus will handle all security.

This will be the test setup, where SoapUI will play the external consumer: Read the complete article here.

How to create a SOA 12.2.1 docker image on OracleLinux (Now Oracle Certified) by Fabio Persico

January 11, 2017 Leave a comment

Introduction

What is docker?

Unless you’ve been living without internet access for the last two years, it would be hard not to at least heard of Docker. But, as an emerging technology not everyone has taken the time to work out what Docker is, where it fits in and how it can benefit you.
So, what exactly is Docker? Here’s what Docker themselves describe it as:
Docker is an open platform for developers and sysadmins of distributed applications.
Essentially, Docker is a container based system for your applications. If you’re used to the concept of virtual servers, Docker provides further levels of abstraction for your application. Here’s a visual representation of how it differs:

Rather than just being one part of the puzzle, Docker provides a number of components and tools to assist with the entire lifecycle management of the application. This includes the container environment, image management and orchestration.
Docker started it’s life as an internal project within a hosting company called dotCloud, but quickly took off once they open sourced it in early 2013. Since then, it’s benefited from over 15,000 software commits from over 900 contributors.

Why use Docker?

Now that you have a basic understanding of Docker, there are a number of great reasons to start using it.

It’s very fast. Start a Docker container can be complete in as little as 50ms. That’s not a typo, it really can be this quick! This is the advantage of having such high levels of abstraction, you reduce the number of components you need to run. This also means that there’s very little to no overhead in it’s implementation.
