Overriding OIC Schedule Parameters by Arya Sanyal

image

A quick recap on schedule parameters

Schedule Parameter feature supports adding scalar variables for Scheduled Orchestration Integrations. These parameter values are available across scheduled runs for the particular Integration and can be overridden by downstream actions like Assign. A maximum of five schedule parameters can be defined per Integration.

Requirements like the following can be achieved by using schedule parameters:

  1. Maintaining the Last Run Time (position) of the scheduled integration to avoid duplicate processing of data.
  2. Process information for specific directory/area/region.

As mentioned above, schedule parameters can be updated in the orchestration by using Assign.

Please refer Oracle Documentation for more details about this feature.

How to override schedule parameters

Today if user wants to invoke a Scheduled Integration (containing schedule parameters) with different parameter values, they need to deactivate the Integration, configure a new default value and activate it back.

Schedule parameter override feature enables user to provide parameter values while invoking the Integration without deactivating it. This feature is controlled by feature flag oic.ics.console.schedule.parameter-override-support.

Once the feature is enabled, a popup will be displayed when user clicks Submit Now or Start Schedule – for Integrations that have schedule parameters defined. Users can view the Default and Current Value of parameters and, if required, input a New Value to override the Current/ Default values. Read the complete article here.

How to enable and use OIC Tracing in less than 5 min by Muthu Palanisamy

image

In this short blog, I’d like to show you how easy it is to enable tracing in OIC Integration and start tracing your integration flows. When Tracing is enabled, OIC Integration prints detailed info before and after each action that is executed (optionally the payload if needed). Hence care should be taken to make sure that it is enabled only for debugging purposes and turned off before going production.

Global Tracing

Let’s assume that you have a requirement where you would like to enable or disable tracing for every integration you have created. You can use the global tracing for accomplishing the same. Enable the Global tracing with below steps:

· Login as an administrator.

· Click Settings on the left side.

· Click Trace on the left side.

· Select Global Tracing On and Click Save on the top right.

· Optionally you can select Include Payload which will additionally write the payload.

Integration Level Tracing

If your requirement is to enable the tracing for one or more integrations and disable tracing for the rest of the integrations, you can use Integration Level tracing. Enable the Integration tracing with below steps:

· Login as an administrator. Read the complete article here.

Using a Library in OIC by Harish Vinayachandran

image

Introduction

A library is a file or a collection of multiple files bundled in a JAR that contain Javascript functions. Library is used within an integration and is executed by a Javascript engine on the server as part of an integration flow.

This document describes the following:

1. Requirements that a Javascript function needs to meet to be used within integration.

2. How to create Javascript file or collection of Javascript files that are suitable to be used in creating a Library. 

1. Javascript function requirements

Following are the requirements based on which Javascript function should be written so that it can be registered and works correctly in OIC.

1.1 Function return values should be named

Consider this example

function add ( param1, param2 ) {
  return param1 + param2;

Even though the above example is a perfectly valid Javascript function it can’t be registered as a library in OIC because without a named return value the library metadata editor is unable to identify parameters returned by this function so that it could be used in mapper for mapping downstream activities in an integration.

OIC requires you to change the above function and name the return parameter like this example. Read the complete article here.

How to use Litmus to create OIC Integration unit tests automatically and run them to catch regressions by Muthu Palanisamy

image 

In this blog, I’d like to show you how easy it is to use Oracle Litmus, a new feature added to Oracle Integration Cloud for creating unit tests automatically with a few clicks and run those tests to catch regressions. Litmus supports the following use cases:

· Enable Integration Cloud users to create unit tests automatically and play them back to catch regressions when they modify their integrations (typically when they enhance an already created integration before making it production).

· Enable Integration Cloud QA to catch product regressions as part of a new release of Integration Cloud.

· Send Oracle a recorded instance so that Oracle can play back the instance to reproduce an issue or a bug. This is difficult without Litmus because all the dependent endpoints and third party adapters might not be available in-house to reproduce the issue. With Litmus, the endpoints are simulated and hence not needed to reproduce the issue.

Enabling Litmus

Let’s assume that you have built an integration which runs as per your requirements and you have completed all your manual testing. Now you are ready to go production. At this point, you might want to create a Litmus Test and want to check that into your source repository. This is so that when you want to change that integration later, you can rely on the Litmus test to catch regressions. Regression in this case is an assertion failing because the response you’re sending to the client has changed due to a bug that was introduced in a mapping as an example.

Enable the Litmus with below steps:

· A feature flag has to be enabled in OIC to enable Oracle Litmus. To turn on the feature flag, open a Service Request with Oracle support.

· Once the feature flag is enabled, login as a developer.

· From the list of integrations displayed in the integrations page, click the inline menu for the integration and click Oracle Litmus -> Enable Litmus Recording

· You can also enable Litmus as part of the Activation as well. Read the complete article here.

Advanced HCM data loader (HDL) processing using OIC HCM adapter by Mani Krishnan

image 

Introduction

Oracle Integration Cloud (OIC) Integration provides adapter for most popular SaaS applications, including Oracle HCM Cloud.  This post focuses on integrating with HCM data loader (HDL) tool of HCM using OIC HCM adapter, multiple HDL file processing and fault handling. Information in this post is applicable to release 18.3.1 of OIC.

HCM Adapter basics

Refer to documentation here, for more information about HCM adapter. At a high level, HCM adapter makes it easier to integrate with HCM cloud using REST , HDL. HCM Extracts and ATOM feeds. As with all OIC adapters,a connection is first created using  Oracle HCM Cloud adapter with endpoints and credentials to the target HCM cloud environment. This connection is then used as invocation target in integration flows, at which time the specifics of the integration such as HDL or ATOM feeds is configured. Note that HCM adapter does not generate HDL-formatted file at this time, although this can be done using OIC. Refer to another A-team blog for guidance on generating HDL files within an integration flow. Below are the sample configuration screens for using HCM adapter for HDL imports.

Integration logic and Implementation

The integration flow elaborated here was demonstrated to a customer who had the following requirements:

  • Multiple HDL files from several source systems should be processed for each run, from FTP location
  • Files should be processed in alpha numeric order of file name. Read the complete article here.

PeopleSoft Integration using Oracle Integration Cloud – Part 2 by Jin Park

image

Now we’re ready to create connections and integration from OIC. If you missed part 1, please go for Part 1 now.  Also my colleague Carlos already wrote excellent blog, Teaching how to integrate Salesforce and Sale Cloud with Oracle Integration Cloud Service so you can look at how to configure outbound message from Salesforce.com and Salesforce Connection with Trigger from OIC.

We know OIC is capable of hybrid integration so you actually can use OIC for SaaS integration scenarios such as SaaS and SaaS or SaaS and on-premises. You may need to set up VPN between your data centre and OIC  using VPNaaS (VPN as a Service from Oracle) or just install OIC connectivity agent inside your organisation network. It’s really depending on the network / security policy of your organisation.

For PeopleSoft, it’s normally located behind corporate firewall so make sure you’ve got VPN is working or connectivity agent installed. So make sure that you’ve got successful web service call from public internet using the SOAP / REAT API test client such as Soap UI / Postman. That would save lots of your time to debug connectivity issue later. Don’t forget to enable web service request logging as well. PeopleSoft provides excellent internal tools to monitor web service request which I will explain next section.

Enable request message logging from PeopleSoft

Visit again to NavBar from top right-hand side from PeopleSoft, then go to Navigator, PeopleTools, Integration Broker, Integration Setup, Services. Now search by service name CI_CONTACT_INFO. After that, select operation CI_CONTACT_INFO_F.V1. Finally select Routings tab and set *Log detail to Header and Detail as below. This will enable web service request message logging which helps you to debug. Read the complete article here.

PeopleSoft Integration using Oracle Integration Cloud – Part 1 by Jin Park

image 

Luckily, I’ve got a chance to look at PeopleSoft integration with other SaaS app using OIC (Oracle Integration Cloud) and decided to share what I learned.

If you’re not familiar with PeopleSoft, please visit PeopleSoft Information Portal and just click hamburger menu on top right-hand side of web page. You will see it covers lots of things.

I’ll explain contact information synchronisation from Salesforce.com into PeopleSoft which is SOAP web service based integration. It is a typical integration use case for PeopleSoft. Will post REST API and file based integration in future as well.

PeopleSoft has excellent middleware layer called Integration Broker. And I’ve chosen SOAP web service for contact information component interface as it would be easiest and simplest way to expose simple business logic in PeopleSoft as SOAP web service. Of course, you have other options such as REST API,  JMS, file based integration, it really depends on organisation’s integration requirements. Read the complete article here.

Enabling the Future Today – Feature Flags in Oracle Integration Cloud by Antony Reynolds

image

Enabling the Future Today

Within Integration cloud we are moving to a model that allows us to trial new features without making them available to everyone.  Everone runs the same codebase but feature flags control what is available to a specific instance.  Why would we do this? For multiple reasons:

  • Gain feedback on new features before rolling them out to the whole user base.
  • Test new features in "the wild" in a controlled manner.
  • Be able to rollback new features that may have unforeseen problems.

How It Works

Each new feature is given a flag that is used to control its availability.  For instance the flag for the small footprint OIC agent was oic.adapters.connectivity-agent.light-weight-agent.  If this flag was enabled for a given OIC instance then they could download the lightweight connectivity agent.  Other OIC instances running the same code but with the flag turned off would not offer the new agent.

Flags are controlled from a central system and can be updated in real time by Oracle development and operations.  This means that feature flags can be turned on very quickly, and also if a problem occurs they can be disabled.

Feature Flag Lifecycle

Feature flags have a lifecycle as illustrated below.

The different stages are:

Internal Only

You may see a product manager demo features on an instance that are not currently available, if using a production pod these may only be available to internal users.  This is where we try things out internally before turning them on for any customers.  Once we are happy with the feature internally we are ready to share it with selected customers and move the feature to Feature Controlled.  Note that this change in stage does not require any code changes, it just alters our internal approval process to enable the feature. Read the complete article here.

API-Key Based Authentication: Quickly and Easily by Anuj Kaushal

image

API-Key based authentication is a simple way for providing secure access to APIs. This involves the following steps:

  1. Pre-requisite: User logs in to the service portal and finds or generates an API-Key.
  2. The API-Key is shared with the client application.
  3. The client application makes a request for a resource using the API key.

Steps required in API Key based authentication.

* An API-key is simply a token that a client provides when making API calls.

How to invoke a REST API protected with an API-Key using Oracle Integration Cloud?

Oracle REST Adapter provides a comprehensive way for consuming external RESTful APIs. It provides a re-usable connection that can be used to specify the security policy for accessing protected APIs. For consuming APIs protected using an API-Key, integration developers should proceed by selecting API Key Based Authentication security policy. Read the complete article here.
