Choosing the best way for SOA Suite and Oracle Service Bus to interact with the Oracle Database

0
1 year ago
by Lucas Jellema in , , , ,

In the past few weeks, I have encountered a similar discussion in various organisations. Each organisation uses either SOA Suite (11g) or Oracle Service Bus (11g) at the core of their SOA infrastructure – either for integration purposes, for workflow and process orchestration or for both. In each organisation, the role of one or more databases is crucial and interaction between the SOA environment and the database is one of the most common and therefore important functions in their enterprise IT environment.

Given the importance, it is only logical that the way(s) chosen for linking the SOA component to the database is carefully selected – and evaluated every now and again. Technology may have progressed, experience may have taught us a lesson or two, the knowledge and skills may have evolved.

Interestingly enough, the number of ways for SOA Suite and OSB to communicate with the database is quite high. This article includes an illustration that shows over 20 different interaction channels that we can choose from with a fairly wild variation of attributes, required skills, productivity and performance characteristics.

Among the choices we face is the question of the communication More >

Publish SOA Composite application as EJB to be invoked from Java applications using EJB Binding

by Lucas Jellema in

With the recent (April 2010) SOA Suite 11g R1 Patch Set 2 (11.1.1.3.0), several new capabilities have been added to the SOA Suite. One these is the EJB Binding. Or rather, an enhanced version of this binding. In previous releases, this binding was available to provide interaction with SDO enabled EJBs – based on a WSDL interface and XML messages. The PS2 release added full Java support to the EJB binding. This means that we do not have to concern ourselves with WSDL and XSD that maps to the Java interface we want to invoke or expose, nor with sending a XML based payload when we invoke the composite service. All we need is the Java interface that describes either the EJB that we want to invoke (for an EJB Binding Reference) or that we want to expose (for an EJB Binding Service).

Steps:

1. Create Composite like always

2. Create a Java Interface (and possibly Java domain classes or bean types describing the structure of the input and ouput of the methods on the EJB (that should correspond with the operations available in the Composite application)

package nl.amis.utilities; public interface FilterAndTranslate { public String translate(String input); }

Note: steps 1 and 2 can be More >

Starting WebLogic managed servers without providing username and password manually – SOA Suite 11g tip

3 years ago
by Jorrit Nijssen in , ,

After installing the Oracle SOA suite 11g, you will notice that you have to enter username and password  for each managed server during startup and shutdown. This in contrary to the administration server where you don't need to enter username and password at startup. I was wondering if there was an easy way of skipping this manual step for the managed servers as well.

And yes, there is an easy and elegant way to prevent entering credentials every startup and shutdown. Just follow these steps:

1 Create a boot.properties file. Create a plain text file called boot.properties with the following content: username=scott password=tiger

2 Place the boot.properties file in the security directory. Save or copy this file in the security directory under the managed server root directory. This directory was not created at installation time, so I had to create it myself. The server root directory is located at <middleware_home>\user_projects\<domain>\<managed_server> i.e. D:\Middleware\user_projects\domains\base_domain\servers\bam_server1.

3 Start the managed server. The server will read the credentials from the boot.properties file and in case of plain text username and More >
