Monitor and control resource usage for groups of entry control blocks in IBM z/TPF
This article describes enhancements in resource monitoring for entry control blocks (ECBs) in IBM z/Transaction Processing Facility (z/TPF), Enterprise Edition V1.1. With the monitoring features in Product Update 12 (PUT12), you can monitor and set limits on resource usage for groups of ECBs and generate usage reports. Understanding and controlling the way that your applications use resources can help you to prevent a family of ECBs within a work stream from using all of the available z/TPF resources.

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.

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.

Capturing and analyzing interface characteristics, Part 1: Capturing integration complexity for BPM and SOA solutions
This two-part article describes a well-tested technique for capturing the fundamental interface characteristics of integration points with back end systems. Integration still accounts for a majority of the design and implementation effort of many IT solutions. Poorly understood integration requirements represent a significant risk to a project. You will see how correct analysis of the integration points improves estimating and technology selection, and ultimately enables a more predictable pattern-based approach to solution design and implementation. Moreover, these articles will specifically highlight the relevance of this technique to enterprise architecture initiatives, such as service-oriented architecture (SOA) and business process management (BPM).

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.

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.
