OCI: When and How to Create an Integration to Call a Service from a Process? By Jan Kettenis

image

With the Oracle Integration Cloud, when you have to call a service from a Process you can choose to call an external service directly or you can put an Integration in between. This article gives some directives why you may want to do the latter, and how to prevent a pitfall that is easy to step in to.

To call a service you have to import the WSDL with it’s XSD’s. With that Business Types are auto-generated for all complexTypes in that XSD. Recently I was refactoring a case where this resulted in some 220 (!) Business Types being generated from 1 single external service, of which only a few were actually used. Granted, it concerned a service with a very complex interface, but for some reason all the external SOAP services we have to consume are moderate to very complex and easily generate 50+ Business Types. Not only that, they also use relatively long namespaces. Can you imagine what will happen when you have to call 5 of these services from the same Process application! You barely can see the forest from the trees, and you may find it pretty difficult to identify the correct Business Type to use for your request. The following example shows the selection list showing the types to chose from when creating a data object for one of the most simple cases we have. Read the complete article here.

Unable to create an error notification rule in Oracle SOA Suite 12.2.1? Patch 26088894 is not the fix by Ahmed Aboulnaga

imageOn Oracle SOA Suite 12.2.1.0.0, when we tried to create an error notification rule to alert on failed ESS scheduled jobs, we experienced an issue where the dropdown was not showing any schedules. Unfortunately, the solution to apply patch 26088894 does not work.

Patch 26088894

Patch 26088894 is a zero downtime ESS patch and applicable for Oracle SOA Suite versions 12.1.3, 12.2.1, 12.2.1.1, and 12.2.1.2.

It addresses the issue of the Adapter Schedule generating a Null Error on the GUI, which may appear to be the issue we experienced, but it is not.

Problem: Error Notification Rule Issue

  1. Log in to the EM Console
  2. Navigate to Scheduling Services > Job Request > Define Schedules
  3. Create a schedule called "Ahmed_Job_10Minutes"
  4. Navigate to SOA > soa-infra (soa_server1) > SOA Infrastructure > Error Notification Rules
  5. Click on Create

When trying to create an error notification rule, you can see that the Schedule dropdown box is empty, preventing us from being able to create a rule. Read the complete article here.

The magic of correlations in SOA, BPM and Oracle Integration Cloud– Virtual Developer Meetup July 6th 2020

Join us for a Virtual Developer Meetup July 6th 2020DeveloperMeetupsVirtual Summer 2020

OIC and especially the process part share a lot with the BPM Suite and BPM sits on top of SOA Suite. So they share a lot of features. Some features are obvious. Others less obvious. Some lesser obvious similarities might be of interest even in the Cloud environment. Today I want to highlight one of those that are in the process-engine from the very first release of Oracle BPEL: correlations. Why is this such a distinctive feature, what can we do with it and how do we implement it?

Get XML Document from SOA Infra table by Martien van den Akker

image

Today I’m investigating a problem in an interaction between Siebel and SOASuite. I needed to find a set of correlated messages, where BPEL expects only one message but gets 2 from Siebel.

To get all the messages that are related to two flows that run parallel based on the same message exchange.
The thing is that of course you want to see the contents of the message in the xml_document. This attribute is a BLOB that contains the parsed document from oracle xml classes. You need the oracle classes to serialize it to a String representation of the document. I found this nice solution from Michael Heyn.
In 12c this did not work right a way. First I had to rename the class to SOAXMLDocument, because I got a Java compilation error complaining that XMLDocument already was in use. I think it conflicts with the imported oracle.xml.parser.v2.XMLDocument class. Renaming it was the simple solution.
Another thing is that in SOA Suite 12c, the documents are apparent. Read the complete article here.

Deploying SOA Composites from Oracle JDeveloper to Oracle SOA in WebLogic Kubernetes Operator Environment by Ravi Pinto

image

Inputs provided by Ashageeta Rao and Vivek Raj

This post provides steps to deploy Oracle SOA composites/applications from Oracle JDeveloper (that runs outside the Kubernetes network) to the SOA instance in WebLogic Kubernetes Operator Environment.

Pre-requisities

Note: Replace entries inside <xxxx> specific to your environment

  1. Get the Kubernetes Cluster Master Address and verify the T3 port which will be used for creating application server connections. You can use below kubectl command to get the T3 port:

kubectl get service <domainUID>-<AdministrationServerName>-external -n  <namespace>-o jsonpath='{.spec.ports[0].nodePort}’

  1. JDeveloper need to access Managed Server during deployment. In WebLogic operator Environment each Managed Servers are pods and cannot be accessed directly by JDeveloper. Hence we need to configure the Managed Server’s reachability:
    1. Decide on external IP address to be used to configure access of Managed Server ( soa cluster). Master or worker node IP address can be used to configure Managed Server accessibility. In case you decide to use some other external IP address, that need to be accessible from Kubernetes Cluster. Here we will be using Kubernetes Cluster Master IP.
    2. Get the pod names of Administration and Managed Servers (i.e. "<domainUID>-<server name>") which will be used to map in /etc/hosts. Read the complete article here.

In this article, we are going to showcase the concept of Integration Versioning in Oracle Integration Cloud.

Some blogs that might help you extend your knowledge

What is Versioning

You might be wondering what a number on software’s, integrations and applications. These numbers are called version of the applications.

For example: If we say download a 12C database. Here what 12 mean is, it is nothing, it’s just version of database. Read the complete article here.

OIC Feature Flag – Data Stitch by Niall Commiskey

image

Data Stitch action in Orchestration

Available to you as feature flag
(oic.ics.console.integration.stitch-action)
Available from version -All text in italics is from ORCL docs.

This is a new capability within the orchestration designer that enables customers to initialize and progressively update complex variables within integration flows. IT specialists can now use the "Global Variables" section of the designer to define new variables in the integration flow that can hold complex content and use the data stitch action to progressively populate and/or manipulate whole or parts of the document. You can simply drag and drop the "Data Stitch" action from the component palette into the canvas and graphically model the data assignments as an ordered sequence of statements to populate scalar or complex variables wholly or partially.  Designers can add multiple data stitch actions at various points in the integration flow to update existing or append new sections to previously declared and populated variables using data from various sources.

Couldn’t have said it better myself, net, net – Data Stitch allows us to create and manipulate complex variables within an integration orchestration. This was something missing in OIC, for those coming from SOA Suite/SOA CS. Read the complete article here.

How to embed CDATA into XML: Oracle Integration Cloud by Ankur Jain

imageThere is a scenario where you are required to consume SOAP API and the API require to send CDATA as part of the request. In the article, we are going to showcase how to embed the CDATA into the XML request in Oracle Integration Cloud.

Let’s first understand what CDATA is?

A Character Data(CDATA) section contains text that will NOT be parsed by a parser. Tags inside a CDATA section will NOT be treated as markup and entities will not be expanded. The primary purpose is for including material such as XML fragments, without needing to escape all the delimiters.

Example of SOAP API having the CDATA

In the below SOAP API request, please see the “<general:BPXML>” and under this CDATA element is there. When you will consume the same into OIC, you will not see the end elements( <wrapper>, <emp>, <name>, etc. ) under CDATA in mapper. If not found in the mapper how you will send the data to SOAP request which is required. Read the complete article here.
