A few weeks ago we faced an interesting challenge: how to propagate a transaction context between Oracle WebLogic 11g and IBM WebSphere 8. Propagating a transaction context between different Java EE servers can sometimes present a problem, especially if those servers support different Java EE versions. WebLogic 11g (10.3.5.0) supports Java EE 5 while WebSphere 8 supports Java EE 6. We successfully solved the problem using WS-Atomic Transaction (WS-AT).

In this post, I will present the main steps how we propagated a transaction from WebLogic (WLS) to WebSphere (WAS). The solution for the opposite direction will follow in a separate post.

Tuning Oracle WebLogic JVM

When trying to improve Oracle WebLogic server performances, scalability and reliability, tuning JVM (Java Virtual Machine) is probably the most important step. However, this is usually far from being an easy task. JVM tuning includes selecting the right JVM, setting the appropriate heap size, selecting the most appropriate GC (garbage collector) strategy, etc. An in-depth discussion is beyond the scope of this post, we will just get familiar with the basic steps:

Java 7 SE introduces JMS (Java Module System)

As an attempt to ease the application’s development in terms of packaging, versioning and deployment, Java 7 will introduce Java Module System (JMS). The Java Module System is being developed under the Java Community Process as JSR 277. The abbreviation itself does not seem very appropriate at first sight, as it can be easily confused with JMS (Java Message Service).

Java Module System’s architecture consists of three main components:

  • Java module
  • Versioning System
  • Repository

Java Module System is a new distribution standard which (similar as JAR file) contains a set of classes and other resources. However, JMS differs from JAR in that the modules can be versioned. A module can be defined as a logical unit of a set of files, resources and other dependencies that can be versioned, packaged and deployed in the module repository. The module repository is where java modules can be stored, discovered and used by other modules.

You can read more about JMS at the following link: http://www.javabeat.net/articles/101-introduction-to-java-module-system-in-java-70-1.html

The use of OSB 11g service result caching feature

OSB 11g (Oracle Service Bus 11g ) provides an interesting feature called service result caching through the use of Oracle Coherence in-memory data grid solution. In this way we can dramatically improve performances of business services if the response  is relatively static.

To enable the use of service result caching globally using the OSB console, we have to open the Operations | Global Settings and set the Result Caching to true.

To enable service result caching on a particular business service, we open the Project Explorer and click on the business service. On the Configuration Details tab, we scroll down and edit the Message Handling Configuration. Then we expand the Advanced Settings. We select the Result Caching checkbox. Next, we have to specify the cache token, which uniquely identifies a particular cache result. This is usually an ID field.  We can also set the cache expiration time.

 

Then we click Next and Save.

Now if the business service locates cache result through a cache key, it returns this result to the client instead of invoking an external service. If the result is not cached (or has expired), the business service invokes the external service, returns the result to the client, and stores the result in cache.

Service result caching works only when the business service is invoked from a proxy service!
