Accessing Oracle B2B metadata from your application by Tiago Teixeira

November 8, 2015 Leave a comment

 

For some time now, Oracle B2B has exposed several methods of accessing it’s partner and message metadata from a custom application. This has been improved even further with B2B 12c.
In this post I’ll guide you through the 2 most common ways of accessing B2B’s metadata programmatically and some news of the 12c version.
The 2 main ways of accessing the metadata stored in B2B are:

  • Web Services exposed by B2B
  • Java API

Web Services exposed by B2B

You can access the WSDL’s for the available web services at the following URL:

http://host_name:port_number/b2b/services/

The most common services are:

  • Outbound Web Service – Works as an internal Listening Channel. Based on the details and headers in the soap:body, the agreement identification is done and the message is routed to the partner.
  • Translation Web Service – Allows to translate documents such as EDI and HL7 from Native to XML format (NativeToXMLService) and from XML to Native format (XMLToNativeService)
  • Query API (GetTPAConfigService) – Allows for retrieval of different metadata such as active agreements for a Trading Partner or checking if a Trading Partner has an agreement for a specific Document.

Document Editor – Defining a custom message (Part 1 of 3) b2b SOA Suite by Bernardo Cabaços

July 22, 2015 Leave a comment

 

clip_image002Oracle Document Editor is an application used for creating and testing document definitions for Oracle B2B.

The document definition (ECS) file is required in B2B for translating and validating documents.

With Document Editor you are able to create new guideline documents or use a template from the comprehensive library of standards available for download. You can download Document Editor and the standard definitions available here.

The available document guideline templates include EDI, HL7, positional flat file (which includes some SAP iDocs), XMLSchema and so on, as seen below.

Thanks to the countless templates available you can easily and quickly create a message definition (ECS) and respective XSD to import to B2B. Making the necessary changes if needed.

Below is an example of a message definition from the template library.

However, specially with Positional Flat File (PFF) messages, you might have to create a custom definition.

In this post I will go through the steps needed to create a custom PFF document definition in Document Editor. This post will be divided in 3 parts, in the first part I will focus on Message Segments’, afterwards I’ll cover the Field’s types and properties, finalizing with testing and XSD generation.

Let’s start by creating an empty definition. Read part I here and read part II here.

B2B 12c – HTTP Generic Channel with transport callout by Bruno Neves Alves

June 4, 2015 Leave a comment

 

First of all, season’s greetings to everyone!

Then, let me introduce this post saying that, already in the version 11g, a generic HTTP listening channel for message posting to B2B using the HTTP protocol was available. Any configured trading partner could use this generic channel to post messages to B2B.

A single common URL was available by default:
http://%5Bhost-name%5D:%5Bhost-port%5D/b2b/httpReceiver

In this way, a single listening channel is able to serve multiple trading partners for every HTTP communications with B2B.

When this channel is used, the process follows the default steps for message processing, namely:

Sender identification (i.e. using HTTP Header);

Document protocol/version/type identification ;

Agreement identification;

Message processing (parsing and validation);

Synchronous delivery to a back-end application.

The only differentiation factor is: since this channel is generic and not configurable or even available on the list of listening channels in B2B console, make it unavailable for channel callout configuration.

This has now changed with the 12c version.

With the version 12c of B2B is now possible to define a generic HTTP transport callout and associate it with a specific transport level callout.

As of now, this is driven by an B2B configuration Fusion Middleware property that needs to be added on Oracle Enterprise Manager Fusion Middleware Control

Installation of Oracle B2B 12c by Tiago Teixeira

June 3, 2015 Leave a comment

 

clip_image002In this post I will quickly go through the steps that are necessary in order to install Oracle B2B and create a SOA domain that you can use.
I will consider that the installation will be used for a development environment and that it is done on the Linux machine.
Note that prior to the installation of B2B you will need to have machine running a Database and perform the installation of Oracle Fusion Middleware 12c Infrastructure and of the Oracle Fusion Middleware 12c SOA Suite and Business Process Management on the same machine where you will be installing B2B. You will also need to have the latest Oracle JDK 7 Update installed on that same machine.
The necessary software can be downloaded using Oracle eDelivery:

  • V44959-01.zip – Latest Oracle JDK 7 Update for Linux x86-64 (Prerequisite)
  • V44416-01.zip – Oracle Fusion Middleware 12c (12.1.3.0.0) Infrastructure (Prerequisite)
  • V44420-01.zip – Oracle Fusion Middleware 12c (12.1.3.0.0) SOA Suite and Business Process Management (Prerequisite)
  • V44421-01.zip – Oracle Fusion Middleware 12c (12.1.3.0.0) B2B and Healthcare

To install Oracle Fusion Middleware 12c Infrastructure please refer to:
Oracle Fusion Middleware Installing and Configuring the Oracle Fusion Middleware Infrastructure
To install Oracle Fusion Middleware 12c SOA Suite and Business Process Management please refer to:
Oracle Fusion Middleware Installing and Configuring Oracle SOA Suite and Business Process Management
I’m considering that a new domain will be configured from scratch. If a SOA domain was already created previously a few of the next steps can be ignored and the existing domain can be extend to include B2B. If that is the case, for the next steps, remember to shutdown any running instances of Weblogic Server.

     1. The first part of the installation will be to install the software:

After you have downloaded the V44421-01.zip file unzip it: Read the complete article here.

B2B 12c – Listening Channel activation and deactivation in bulk Bruno Neves Alves

April 17, 2015 Leave a comment

 

clip_image002With the version 12c of B2B the possibility to activate and deactivate all listening channels in one single command was introduced. Previously, it was necessary to provide the name of the listening channels to perform the action, what, in scenarios with a considerable number of listening channels, made the task ineffective.

Different scenarios can be pointed out where this functionality is extremely useful:

· After importing a B2B configuration the channels are always in deactivated status. This command can be then executed in order to activate all the listening channels in bulk;

· Deactivate all listening channels to stop momentously all message consumption for corrective or preventive reasons into B2B or back-end applications;

· Switching the message consumption between two environments;

The feature is also provided in a command line based approach since is an extension to the already existing feature of enable/disable a particular listening channel. Therefore it is respecting the same prerequisites.

Prior to executing any B2B command line tool is necessary to set the following environment variables: Read the complete article here.

B2B Event Queue Management for Emergency by Shub Lahiri

February 20, 2015 Leave a comment

 

Executive Overview

clip_image002Many customers face a crisis in production system when, for some reason, they end up with several B2B messages stacked up in the system, that may not be of a high priority to be processed at that point in time. In other words, it would greatly help many customers if, in such critical situations, they had an option to flush the backed-up messages from the system for later resolution and simply continue with processing of the current messages.
A-Team has been involved with different customers worldwide helping them implement such a solution for emergency use. Without getting into too much technical details, a high-level approach for such a solution is discussed here. The methodology accomplishes two key tasks, that are of primary importance during an emergency crisis within a B2B production gateway:

  • Allows to flush the event queue while the gateway is down, so that the gateway can be brought up quickly
  • Introspect the messages created from the event queue for resubmission or rejection

The primary objective of this framework is to allow the B2B engine to come back up quickly after flushing the messages from the event queue. The recovery or resubmission of messages is usually reviewed manually by the operations and business teams off-line and takes a longer cycle to complete. But this should not affect the down-time of the production system after the fast removal of the messages from the event queue. The downtime, thus encountered, is only driven by the first task, as listed above.

Solution Approach

Overview

The solution consists of immediate cleanup of messages from the system. The entries will be stored in files. After the files are created, the gateway will be ready for normal processing without any impact of messages that were previously present in the system.
After the gateway is opened for normal business, the analysis of the file contents can be carried out, in parallel, to decide which messages will be resubmitted or discarded. This analysis can be done via scripts to extract relevant pieces of business data for the messages removed. The scripts are decoupled for various types of transient message data and built on basic query utilities. The basic building blocks for data introspection are typically custom scripts, that are created based on specific business needs for analysis.
The analysis will create 2 lists of message IDs – one for resubmission and the other for rejection. Existing command-line utilities can be invoked to resubmit the messages in a scripted loop with configurable delays in between the resubmissions. For rejection, there is typically no processing required. However, the list of IDs will be used to update the database to reflect a final state for the appropriate messages.

Tasks and Activities

The following sections describes the tasks in greater detail. Sections I and II cover the activities that need to be completed while the gateway is down. Sections III and IV include the post-mortem phase for analysis of messages removed from the system.
The flowchart below can be used as a reference for the critical cleanup tasks covered in Sections I and II.

I. Preparation of Environment Read the complete article here.
