Monitoring the JVM server in CICS with IBM Support Assistant
Memory leaks in Java programs can be as critical as they are in programs written in other languages. While Java has a Garbage Collector, it sometimes cannot remove objects because they are still referenced. Therefore memory leaks require you to first, locate them, and second, identify the class responsible. This article uses a sample Java program running in the CICS JVM server to show you how to locate a memory leak and identify the class responsible.

Techdoc: WebSphere for z/OS - Feature Pack for Web Services
Learn what the Feature Pack for Web Services (FPWS) for WebSphere Application Server on z/OS provides, and how to install and configure it. You update an existing configuration so it can link to and make use of this new functionality. The process is not difficult, but it may be unfamiliar territory for those who have not done this before. So this paper provides a step-by-step guide to installing, configuring and validating the new Feature Pack for Web Services.

Build a resilient SOA infrastructure, Part 1: Why blocking application server threads can lead to a brittle SOA
Resiliency -- defined as the continued availability and performance of a service despite negative changes in its environment -- is vital in a Service-Oriented Architecture (SOA). An SOA infrastructure must ensure that a service is highly available regardless of unpredictable conditions, such as sudden and significant degradation of network latency, increase in database response times, or degradation of dependant services. This article, the first in a series that describes design issues and techniques for building resilient SOA infrastructures, focuses on how IBM WebSphere Application Server for z/OS factors into the SOA and how it contributes to SOA resiliency.

Exposing a CICS program as a Web service using IBM Rational Application Developer
IBM Rational Application Developer v6.0.0.1 provides new tooling to simplify the creation of J2EE applications that use the J2EE Connector Architecture to access applications running on legacy systems. This article will start with a simple CICS program, and show how basic wizards can be used to expose the program as a Web service running on IBM WebSphere Application Server. It will also cover some of the pitfalls encountered on the way. This will be useful to people wishing to use their legacy CICS applications in a Service-Oriented Architecture.
