|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.

|Comment lines: Defeat image sprawl, once and for all
Virtualization and cloud computing make it very easy to create new virtual images, but as image catalogs grow, finding and locating the right images gets harder. New images are created because it is easier to create a new image than it is to figure out what existing image might be reusable, creating "image sprawl." Unless you address how to more effectively build and manage your virtual images, you will not realize the full benefits of the cloud. Two new IBM capabilities, the Virtual Image Library and the Image Construction and Composition Tool, can help you quickly understand the content of your images and build reusable, parameterized images.

|Solution isolation in service-oriented environments
Many IT environments are often designed and deployed in what you might call a vertical fashion. This means that each line of business has its own set of solutions, which are isolated from each other. Among other things, the concept of SOA is an attempt to establish a more horizontal view, promoting better reuse of IT functionality and operational resources across organizational boundaries. And while this is all good, of course, it requires extra care and due diligence to achieve operational excellence. This article describes some of the operational challenges introduced by this view and suggests approaches for how to address them, namely by isolating solution components from each other. Included are examples showing how this isolation can happen on many levels, either individually or in concert, all based on a set of prioritized criteria.

If this is a characteristic that your environment shares, then you need to be aware of the destabilizing nature of this “malpractice” – and you need a plan for addressing the situation to improve stability.

|Re-engineering applications using optimized local adapters on WebSphere Application Server for z/OS
IBM WebSphere Application Server for z/OS V7 introduced optimized local adapters support to provide an optimized, high performance bi-directional connector for WebSphere Application Server and applications running in external z/OS address spaces. Optimized local adapters provide support for two-way synchronous local calling between applications in WebSphere Application Server and z/OS batch, CICS, IMS, ALCS, and USS processes. Optimized local adapters achieve optimal performance and very low latency by extending the WebSphere Application Server for z/OS local communications feature, which is based on z/OS cross memory services. It provides security context propagation in each direction with identity assertion, and it provides two-phase commit transaction support for calls between WebSphere Application Server and CICS. This article provides insight into how optimized local adapters work and how you can use the feature to help re-engineer and modernize legacy z/OS applications.
