Comment lines: Software solution resiliency guidelines can help prevent bad behavior
Unit testing, system functional testing, performance testing, and the like have traditionally been the only kind of testing that is performed in some form or fashion when implementing a new or updated system. Unfortunately, often overlooked is resiliency testing. The result is that when resiliency issues surface, operations, administration, network, systems, and database personnel all scramble to find the root cause. This typically leads to a relatively lengthy project to ensure the solution becomes - and stays - resilient. This article offers guidelines you can follow to ensure the IT solution is more resilient to environmental changes.

An introduction to service mapping: Integrating evolving web services in WebSphere Application Server V8.5.5
SOAs and web services evolve over time — new versions of services are deployed or brand new services must be integrated with existing clients. Typically, development effort must be expended to ensure that web service clients continue to work with the web service providers. IBM WebSphere Application Server V8.5.5 and IBM Rational Application Developer V9.0 introduce service mapping, a feature that enables you to remove the dependence of the service client on both the location and interface of the service provider via the interception, routing, and transformation of requests and responses between service clients and service providers. This article explains the concepts of service mapping and provides a working example, showing how multiple versions of a service provider can be called by the original service client via the development and use of service mapping technologies.

Case study: Tuning WebSphere Application Server V7 and V8 for performance
IBM WebSphere Application Server supports an ever-growing range of applications, each with their own unique set of features, requirements, and services. Just as no two applications will use an application server in exactly the same way, no single set of tuning parameters will likely provide the best performance for any two different applications. Most applications will generally realize some performance improvement from tuning in three core areas: the JVM, thread pools, and connection pools. This article uses the Apache DayTrader Peformance Benchmark Sample application to demonstrate what you can tune and how to go about tuning it, depending on the major server components and resources that your application uses. Updated for WebSphere Application Server V8.

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.
