SOA 12.2.1 New Feature – End to End JSON and Javascript Example by Krishna Hanumantharao

clip_image002SOA 12.2.1 provides support for end-to-end JSON and Javascript. We don’t have do internal mapping between XML and JSON as in 12.1.3.

As part of this post, let us implement a simple REST service to demonstrate this new feature – End to End JSON with Javascript.

Let us create a very simple SOA Composite which exposes a JSON based REST interface, manipulates the values using Javascript and calls an external JSON based service.

Rest Service

External JSON Service Setup

For external JSON based REST service let us use a dummy JSON Server. Read the complete article here.

Processing large XML files in the SOA Suite by Emiel Paasschens

clip_image002Read large XML files in chunks

Introduction

At my current project, XML files are uploaded by the end-user to be processed in the Oracle SOA Suite. The XML files contain information about employers and their employees. Because an employer can have hundreds and even thousands of employees, these XML files can be quite large.
Processing such large XML files consumes a lot of memory and can be a bottleneck especially when multiple end users are uploading large XML files at the same time. It even can cause a server to crash because of an OutOfMemory problem.
The best way to solve is, is to read and process the large XML files in chunks, so read and process XML fragments instead of the full XML file.
My colleague, Aldo Schaap, already did and describes this for CSV files in his blog “Processing large files through SOA Suite using Synchronous File Read“. I thankfully used his blog to do the same for XML processing. However, a few things are slightly different in reading XML instead of CSV, so that’s the reason for this blog.
Another reason is that I ran into another problem, which I will describe later on in this blog. To be able to solve this problem I have to ‘pre transform’ the XML file. This means the XML file needs to be transformed before it is read by the SOA Suite. To achieve this I used the pre processing features of the file adapter with a custom (Java) valve. This pre en post processing is described in the blog “SOA Suite File Adapter Pre and Post processing using Valves and Pipelines” by Lucas Jellema.
The combination of these two blogs provided me the solution for my problem.

Problem Description

Back to my problem. The large XML files, which have to be parsed, contain one ‘Message’ element as root. This root element contains one or more employers with some basic employers information and each employer can contain multiple employee elements, up to thousands, with employee information and employment information. In the real use case the XML structure contains Dutch element names and the XML is very specific about the business problem. For the purpose of this blog, I’ve reduced the problem to a basic XML structure with English names and used some basic sample data. XSD source: Read the complete article here.

SOA & BPM 12.2.1 Installation and Configuration Workshop by John VanSant


clip_image002Overview of Workshop

This workshop will guide the participant through the installation of a non-development environment for SOA and BPM Suite v12.2.1. This workshop won’t cover the installation of the SOA Quickstart install, but the installation of the production software. Some notable differences between the Quickstart install and production bits are:

  • The Quickstart installer doesn’t require an Oracle Database but uses a Java Database. In order to use BAM, an Oracle Database is required so the edelivery installation packages should be used if BAM is going to be used with SOA and/or BPM.
  • The Quickstart installer limits domains to a single managed server.
  • The Quickstart installer doesn’t support B2B domains.
  • The Quickstart installer also doesn’t support the ESS (Enterprise System Scheduler)

The overall steps in this workshop are:

1. Download the software and install Java SE

2. Install Fusion Middleware 12c Foundation

3. Install Oracle Database 12c Enterprise Edition

4. Install SOA and BPM Suite 12c

5. Patch the SOA and BPM 12c installation

6. Create the required Database Schemas to support a domain

7. Create & Configure a test domain

8. Smoke-test the new domain

BPM 12c Subprocesses (Part 2 of 3): Embedded Subprocess by Antonis Antoniou

clip_image001

In this second blog on sub-processes we will explore the embedded sub-processes, also referred to as inline sub-processes and as the name implies this is a sub-process type that consists of a series of activities (for example tasks, gateways, events, etc.) that resides within the parent process.

An embedded sub-process has certain distinct characteristics such as they always begin with a none start event and end with a non end event, they do not contain swimlanes and most importantly they share their parent's context, meaning they can access parent process data which simplifies things since you are not required to define input and output parameters and pass them as data objects. If required you can defined data objects that are local to your embedded sub-process.
An embedded sub-process is mainly used to simplify the process model by grouping activities together into an embedded sub-process that can be collapsed or expanded to hide and show the implementation details.
Another common use of the embedded sub-process is to define loops which will be the case with the sample process that we will implement as part of this blog post.
We will be implementing a very simple process which will make use of the embedded sub-process to loop through a list of order items for review.
Create the basic BPM application and BPM project (i named it OracleBPM12cEmbeddedSubProcessDemoApp and OracleBPM12cEmbeddedSubProcessDemo respectively) and choose "Empty Composite" in step 3 of the "Create BPM Application" wizard since we will first create the the XSD schema file to describe our process's input and output parameters.

Integrate Oracle SOA Healthcare and Oracle SOA Suite back-end composites across segregated domains by Bruno Neves Alves


clip_image001When implementing a composite with JDeveloper, one of the available adapters - since early versions of the 11g release of Oracle SOA Suite - is the Healthcare Adapter. This adapter allows to connect, both as exposed service (inbound) and as reference (outbound), to an Oracle SOA Suite for Healthcare Integration (SSHI) installation enabling document trading with other applications in the healthcare ecosystem.

The SSHI is mostly used for  HL7 documents exchange between back-end healthcare solutions and its satellite applications. However, in some other cases, SSHI is even implemented as a hub for document exchange, connecting heterogeneous healthcare applications.

The Healthcare adapter comes in two integration type flavors:

  • Default - in memory integration;
  • JMS - integration based on AQ or JMS queues.

The first one, based in memory, allows the SSHI application to integrate with the composites through the Healthcare Adapter using the JVM memory - what makes the integration quite efficient and fast - however, with one limitation: both SSHI and the SOA composites have to be deployed in the same domain.

Now, one of the best practices that should be taken in consideration when architecturing a large scale integration platform with SSHI and SOA Suite is to deploy the SSHI and the SOA back-end composite application in separated domains, favoring:

  • Tuning and configuration - domain configuration isolation is key to reach the sweet spot in such implementation. The domain where the composites are being deployed will likely demand different configuration compared with the SSHI dedicated one. This segregation will allow to apply different tuning strategies to one another.
  • Database partitioning - The fact that the SSHI and back-end composite application are persisting into separated SOA_INFRA schemas promotes separated database grow management strategies. This empowers an adequate data partitioning and purging strategies for each of the domains.

As explained, for an in memory integration, both domains needs to rely over the same JVM, therefore, separating the domains will presuppose two separated JVMs leaving the Default options as unusable.

This article demonstrates how the JMS integration can be implemented between SSHI and the back-end application available from two separated domains.
For questions of demonstrability it will follow a simplistic SSHI as a hub implementation. Because of that, the article additionally covers all the necessary steps to implement the integration scenario between two healthcare MLLP endpoints through a composite back-end.

Ingredients
  • 2 separated SOA Suite domains with cross domain authentication active
  • 1 inbound Weblogic JMS queue and connection factory
  • 1 outbound Weblogic JMS  queue and connection factory
  • 1 composite with two Healthcare Adapters, one as exposed service and another one as reference
  • 1 SSHI MLLP inbound endpoint
  • 1 SSHI MLLP outbound endpoint
  • 1 "Send to Internal" Internal Delivery Channel
  • 1 "Receive from Internal" Internal Delivery Channel
