Oracle BPM: Time for Time Out (2)

In a previous blog posting I discussed a solution to re-initiate a scope in BPMN that is supposed to time out after some time. In this posting I discuss how that solution inspires a couple of other use cases where a time out has to be re-initiated by calling an operation on the process.

In the following process model there are three flow, for three different use cases to re-initiate the time-out of:

  1. A process (more...)

Oracle Weblogic: Tackling Class Loading Issues for SOA Infra

This blog article discusses how to address class loading issues with the Oracle SOA Infra. It's prime "raison d'etre" being a memory dump of something I don't do often, but may spend significant time in finding out how to do it again.

Some time ago I lost valuable time because some library being deployed twice, once in the wrong place ([SOA_HOME]/lib folder) and once in the right place ([SOA_HOME]/soa/modules/oracle.soa.ext_11.1.1). In this (more...)

Oracle BPM: Time for Time Out

In this posting I describe how to time out a specific BPM scope with the option to re-initiate the timer.

In case you need to model a time out for a specific scope within a process where you want to be able to modify the time out run-time, then you can model it similar to this:

A parallel flow is used where the top flow covers the main process, and the bottom flow handles the (more...)

Oracle BPM: Hiding Faults from BPM? Don’t use Service Activity!

In the following I explain how you can hide faults from BPM by not using (synchronous) Service activities, but (asynchronous) Send/Receive activities instead.

When calling services from a BPM process, you should think about where you want faults to show up and to be handled. This is specifically of interest when you have some integration layer between your BPM processes and external services that you call to abstract the external services from the BPM process. (more...)

Oracle BPM: Loops and Gateway Struggles

If there is one issue that I see people often struggle with, then it is the use of loops in combination with gateways. The following discusses a few cases.

The following picture shows several loops in combination with a Parallel gateway, of which some are valid and some not. The same holds for the Inclusive gateway.

To understand why some loops are valid and other not, you have to realize that at the beginning of (more...)

Oracle SOA/BPM 12c: Contract WSDL Only in MDS?

In this posting I will discuss if it is a good idea to only have a (contract) WSDL in the MDS, and let your implementing composite point to that, instead of having a WSDL in the project itself (as well).

When developing SCA composites with JDeveloper, initially your WSDL will be in the project of the composite. Some people put a contract WSDL in the MDS, and then let the code of the SCA composite (more...)

Oracle Process Cloud Services advanced form validation and control

In my previous blogpost I explained how forms in PCS are created and what basic options are available. Now I would like to go deeper into the details of rules and business objects.

Let’s start with rules.

The form canvas has a row of tiny buttons in the top right. The left one switches between rules and the formĀ itself. Click that and the canvas changes to the list of rules (if already created). A new (more...)

Creating and editing forms in Process Cloud Service

For who is PCS?

Oracle Process Cloud Service is a PaaS (Platform as a Service) offering which centers around designing and managing (stand alone) business processes in the cloud. The focus is once again on business analysts and other non-technical people to automate business processes. Oracle has keyed them “citizen developers”. One of the features is the option to create forms that fulfill the “human task” interaction in the BPM process.

A walkthrough for creating (more...)

Oracle BPM 11g/12c: How to Catch an Event in the Same Process

A customer of mine was kind of surprised that when you throw an event in a component of a SCA composite, that the same component cannot catch that event and act upon it. This is a known limitation, for which there is a work-around, which I will discuss in this article.

The work-around is quite simple: another loosely coupled component in the same composite can listen to the event, so all you have to do (more...)

Why in Oracle BPM/SOA Suite Attaching a Fault Policy to a Synchronous Service Is Not a Good Idea

In this posting I will explain why in the Oracle BPM/SOA Suite you should not attach fault policies to synchronous services.

The other day I investigated some BPM process instance that had an unrecoverable error. It was calling a synchronous service, that on its turn was calling another synchronous service, that on its turn was calling a external, synchronous service exposed through the Oracle Service Bus. That latter call failed (due to a timeout). As (more...)

How to Keep Your Business Process Looking Simple

There are two key words in Business Process Management Notation (and Language) or BPMN for short that very often seemed to be missed. The first is "business" the second "management". In this posting I will discuss the significance of the first, and how you are in control of that.

In BPMN the word business does not wants to express that it is "just" about modeling business processes. The idea is also that these models should (more...)

Oracle SOA/BPM: Payload Validation per Composite

In this article I will explain how you can enable payload validation in the Oracle SOA/BPM Suite per composite, both design and deployment time. This works for 11g as well as 12c

When developing BPM processes or SOA services it is advisable enable payload validation on the development server. The reason being that this will force you to work with more representable test data, and in some occasions help you preventing coding errors (like (more...)

Oracle SOA/BPM 12c: Propagation of Flow Instance Title and Instance Abortion

Recently I wrote this posting regarding an improvement for setting the title of a flow instance in Oracle BPEL, and BPMN 12c. In this posting I will discuss two related improvements that comes with SOA/BPM Suite 12c, being that the flow instance abortion is automatically propagated from one instance to the other, as well as the flow instance title. Or more precisely, for every child instance the initiating instance is shown together with its name.


How to Hide Actions in OBPM 12c Workspace

In this article I explain how to hide the actions in the drop-down in Workspace.

In some situations you may need to hide the actions that are shown in the Actions drop-down in Workspace.

One way to do so is by configuring the access that users with a specific Workspace role have for a specific task (not to be confused with a swim-lane role), by going to the task definition -> Access -> Actions. For (more...)

Starting a Process using a Timer with a Duration in Oracle BPM

In this blog article I explain three options to configure a timer start event based upon some configurable duration.

As far as I know firing a timer based on a duration is only applicable in case of a Timer Event Sub-process. Let me know if you think otherwise.

In case of an Event Sub-process the timer starts at the same moment when the process instance starts. There is no way to change it at any (more...)

Using a Parallel Gateway without a Merge in OBPM

In this blog article I give a brief explanation regarding some aspect of the behavior of the parallel gateway in Oracle BPM.

For the BPMN modelers among us, I have a small quiz.

Given a process model like this, what would be the behavior of Oracle BPM?

  1. It does not compile because OBPM thinks it is not valid BPMN
  2. The flows with Activity 1 and 2 are merged, the token moves to the End event (more...)

Groovy Time! How to use XML dateTime and duration in BPM 12c

In this article I show some examples of handling XML dateTime and durations in Groovy in the context of a Oracle BPM 12c application.

Working with dates and durations in Java has always been painful. Mainly because date and time is a complex thing, with different formats and time zones and all, but I sometimes wonder if it has not been made overly complex. Anyway. Working with XML dates is even more complex because the (more...)

Oracle BPEL & BPM 12c Set Flow Instance Title

In this article I describe how to set the instance title for a composite in Oracle BPEL or BPM 12c.

Sometimes little, annoying things that are fixed with a new release can give great joy. With 11g you could set the composite instance title using the (advanced) XPath function setCompositeInstanceTitle(). This helps to find or identify instances in Enterprise Manager. However, for high volume composites you may want to configure in-memory-optimization as well by adding (more...)

Oracle and Adaptive Case Management: Part 2

This posting is the second of a series about Oracle Adaptive Case Management. The first one can be found here. I discuss the different options to define an activity, and the setting you can use to configure when and how activities are started.

There are two ways to implement an activity in ACM. The first one is by creating a Human Task and then "promote" it (as it is called) to an activity. The other (more...)

Oracle and Adaptive Case Management: Part 1

In this blog posting I address four key concepts that are used in Oracle Adaptive Case Management, or ACM for short. This article is the first in a series on ACM.

Recently I was involved in an Oracle Adaptive Case Management (ACM) project. Although some people involved knew about case management in general, it turned out that not everyone immediately understood how case management works with Oracle ACM. As you may be one of them, (more...)
