Building the Content Based Routing Solution on Microsoft Platform

by Richard Seroter | September 2010 | Architecture & Analysis Enterprise Articles Microsoft

In the previous article, Content Based Routing on Microsoft Platform, we took a look at how to send data messages to the correct target system.

In this article by Richard Seroter, co-author of Applied Architecture Patterns on the Microsoft Platform, we will actually construct a working version of the proposed solution, which will leverage core components of .NET 4.0 (WCF and Windows Workflow Services) as well as the AppFabric extensions to IIS. Note that for this demonstration, we are only building the first aspect, which accepts orders, not the second piece which supports querying the status of a given order.

Introduction to Oracle Service Bus & Oracle Service Registry

by Marcel Krizevnik Matjaz B. Juric | September 2010 | BPEL Enterprise Articles SOA Oracle

In this article, by Matjaz B. Juric & Marcel Krizevnik, authors of WS-BPEL 2.0 for SOA Composite Applications with Oracle SOA Suite 11g, we will get familiar with Oracle Service Bus (OSB), the Oracle strategic ESB. First, we will look at the OSB architecture and features. Then we will demonstrate the use of OSB on our Travel business process. We will show the combined use of OSB and Oracle Service Registry (OSR) to provide very high fexibility. Therefore, we will frst publish the EmployeeTravelStatus service to the OSR. Then, we will open the Oracle Service Bus Console, create a new project, and import the service and all related artifacts from OSR. Next, we will create a proxy service for the EmployeeTravelStatus service. We will show how to defne the proxy service message fow. We will also demonstrate some advanced features of OSB, such as service result caching. Then, we will deploy the new version of EmployeeTravelStatus service with a slightly different interface and show how OSB can absorb these changes by simply adding an XSL transformation. Finally, we will publish the new proxy service to OSR and modify the corresponding reference binding component in our SOA composite, so that it will retrieve the proxy endpoint address from OSR in runtime.

In this article, we will discuss the following:

  • Oracle Service Bus architecture and features
  • Publishing services to OSR

Debugging PL/SQL in Oracle SQL Developer 2.1

by Sue Harper | September 2010 | Enterprise Articles Oracle

Once your PL/SQL code has successfully compiled, it is important to review it to make sure it does what is required and that it performs well. You can consider a number of approaches when tuning and testing code. These approaches include:

  • Debugging—run the code and add break points to stop and inspect areas of concern.
  • SQL performance—use Explain Plan results to review the performance.
  • PL/SQL performance—use the PL/SQL Hierarchical Profiler to identify bottlenecks.
  • Unit testing—review edge cases and general function testing. Does the code do what you intended it to do?

In this article by Sue Harper, author of Oracle SQL Developer 2.1, we'll review the debugger. We will see how to debug PL/SQL packages, procedures, and functions.
