Forwarding Messages from WebLogic to TIBCO EMS

Introduction Messaging is one of those technologies that have been around for decades, but only recently people got aware of the important role that messaging plays to any software-based architecture. Any use case that requires messages to be exchanged between systems in a reliable, fault-tolerant and scalable way may leverage messaging to fulfill its needs. […]

Introduction In the part 1 and part 2 of this blog, I’ve covered the overview, setup and OSB design, in this part 3 of the blog, I will be covering the PCS design. PCS Design In PCS, we will need to create 2 web service connectors, the first connector is for DOCS folder creation using […]

Integrating PCS, DOCS and BI Publisher using OSB/SOACS – Part 2

Introduction In this part 2 of the blog, we will examine the OSB design used in this demonstration.  OSB is used as an integration layer for PCS, DOCS and BI Publisher as OSB plays an important role acting as an integration layer for protocol translation and message transformation, and it will also serve as a […]

Integrating PCS, DOCS and BI Publisher using OSB/SOACS – Part 1

Introduction In this 3 part blog series, I will be demonstrating on how to use PCS to invoke OSB (On-Prem or SOACS) services and upload a report/doc generated using BI Publisher to DOCS.  The following components are used in this demonstration: Oracle Document Cloud Service (DOCS) Process Cloud Service (PCS) with DOCS integration configured. BI […]

Poller Transport Based Service Management Scripts

The polling transports (Email, File, FTP) in Service Bus only poll on one managed server for a given service, which is defined in the service configuration.  However, if the polling managed server is not running, polling is not resumed automatically on another managed server in the cluster. The zip file below contains a collection of […]

Custom Transports in Oracle Service Bus 12.2.1

Oracle Service Bus (or Service Bus for short) provides a very powerful set of APIs that allow experienced Java developers to create custom transport providers. This is called Service Bus Transport SDK. By using this SDK, it is possible to create custom transport providers to handle both inbound and outbound message handling for specific protocols, […]

Oracle Service Bus Transport for Apache Kafka (Part 2)

Introduction The first part of this article briefly discussed the motivations that leads to the usage of Kafka in software architectures, and also focused on how the Kafka transport can be installed and how to create Proxy and Business services to read and write from/to Kafka topics. As expected, as more people use the Kafka […]

Oracle Service Bus Transport for Apache Kafka (Part 1)

Introduction Few of us realize it but the heart of OOP (Object-Oriented Programming) has more to do with messaging than with objects and classes, or with related design principles like inheritance and polymorphism. At very beginning, OOP was designed to help developers implement data exchange between objects, so these objects would be coordinated to execute […]

REST Adapter and JSON Translator in SOA/OSB 12.1.3

If you are using REST adapter in SOA/OSB 12.1.3, you would probably encounter some requirements that you would need to response with a JSON array format which has no object name or name/value pairs, and must be a valid format according to RFC4627 specification. For example: [“USA”,”Canada”,”Brazil”,”Australia”,”China”,”India”] In SOA/OSB 12.1.3, the REST adapter requires you […]

Caching in OSB 12c without Out-Of-Process Coherence Servers

Introduction One of the most popular use cases for Oracle Service Bus (OSB) is the mediation of synchronous service interactions. In this scenario, a client invokes the service through a proxy instead of the actual service endpoint, guaranteeing that the consumer is decoupled from the producer. This type of architecture allows producers to be changed […]

Passing User Context When Invoking ADF BC SOAP Web Services

Introduction ADF web applications often use session-scoped user context information that is also used in the ADF Business Components (ADF BC) layer. For example, the user language might be used to query language-specific data from the database. This article explains how this user context can be set up when accessing the ADF BC layer through […]

Using OSB 12.1.3 Resequencer

Resequencer feature has been added to Oracle Service Bus 12c (12.1.3), it utilises the same resequencer engine as Oracle Mediator.  The objective of this feature is to provide you with the ability to resequence the incoming messages that arrive in random order and send them to the target services in an orderly manner.  In this […]

One-Way Authentication Policies in OSB

Introduction Sometimes, using OSB, it may be necessary to attach credentials, such as username and password, on an outbound SOAP request to a remote server for authentication. While the OWSM policy store available with WebLogic Server provides policies that can inject username and password (e.g. “oracle/wss_username_token_over_ssl_client_policy”), OSB causes OWSM policies to be enforced on the […]

Interoperability between Microsoft and SOA Suite 12c

Introduction During the design of SOA applications it is inevitable that from time to time you will need to interface with Microsoft-based applications. While technologies like SOAP and REST do a great job when request-reply communication is needed, most people struggle when a messaging-based communication is required. This blog will present two approaches to get messaging working between Microsoft […]

OSB MQ Transport Tuning – Proxy Service threads

The MQ Transport is a polling transport.  At the user defined interval, a polling thread, fired by a timer, checks for new messages to process on a designated queue.  If messages are found, a number of worker thread requests are scheduled to execute via the WebLogic work scheduler.  Each of these worker threads will get […]

OSB Http Transport Client Certificate Authentication Common Pitfall

I recently worked with a customer to help them resolve some issues they were having with configuring client certificate authentication (2-way SSL) for an Http Business Service in Oracle Service Bus (OSB).  This blog is to discuss a common issue encountered and how to fix it. The customer’s use case was to invoke a service […]

OSB Threading and the HTTP Transport White Paper

I have created a white paper explaining the OSB threading model with a focus on the HTTP transport.  I have heard from several customers who have experienced difficulty with tuning HTTP services with relation to the use of work managers.  This paper’s goal is to explain the threads involved in servicing a proxy and how […]

Oracle Service Bus JMS Deployments Utility

For proxy services utilizing the JMS transport, OSB receives messages from destinations by using an MDB.  These MDBs get generated and deployed during activation of the service configuration.  OSB creates a random, unique name for the J2EE application that gets deployed to WLS.  The name starts with “_ALSB_” and ends in a unique series of […]

Building OSB projects with Maven and removing the eclipse dependency

In this earlier post, I talked about a way to automate the build and deployment for OSB, but I did not go so far as to get that working in Maven, though you certainly could.  But, OSB PS6 has added a new tool called configjar which lets you build a sbconfig.jar file without needing to […]

Handling HTTP Compression with OSB

HTTP compression is a mechanism that enables client and server to exchange compressed data over HTTP to improve performance by better use the bandwidth. Oracle Service Bus (OSB) doesn’t support gzip compression by default, this might create a potential performance issue if the large payload is exchanged. It may become even more serious if data […]
