Comment lines: Encrypting WebSphere Application Server system passwords — if you insist
IBM WebSphere Application Server stores system passwords in files that are simply encoded. To support clients who want to implement their own password storage mechanism, WebSphere Application Server has provided a System Programming Interface (SPI) to do so. Encrypting these system passwords can provide some marginal additional security benefits for a specific class of vulnerability (poorly implemented application code), but it cannot provide defense against a malicious programmer or a determined attack. If you insist on implementing a password encryption solution, here is one example of how you could achieve this using the SPI.

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.

Rational Application Developer enhancements for WebSphere Optimized Local Adapters present new opportunities for end to end EIS integration
Enhancements to IBM Rational Application Developer for WebSphere Software V9.0.1 added new capabilities for application integration between disparate enterprise environments, such as those made up of IBM WebSphere Application Server, CICS, IMS, and batch processing on z/OS, and environments that contain SAP, Oracle, Seibel, and other IBM WebSphere Adapter-supported enterprise information systems. Support for optimized local adapters is now included in Rational Application Developer, offering optimized bi-directional calling between WebSphere Application Server for z/OS and external address space applications on the same z/OS system. Combining optimized local adapters with the WebSphere Adapters support presents many new opportunities for real time interactions between applications and environments that were too complex to realistically handle in the past. This article presents one such scenario, in which a CICS application uses optimized local adapters and WebSphere Application Server for z/OS to communicate with applications running on SAP servers.

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.

Maintaining high availability when implementing WebSphere MQ clusters in a clustered WebSphere Application Server environment.
Both WebSphere Application Server clusters and WebSphere MQ clusters are widely used to provide high availability and balance workloads across an enterprise. Combining these technologies helps you scale both your WebSphere Application Server and WebSphere MQ infrastructures, and enables WebSphere Application Server applications to use the faster bindings mode to retrieve messages from WebSphere MQ queues. However, without careful planning, the combination of WebSphere Application Server clusters and WebSphere MQ clusters can actually cause reduced overall availability, message build-up on queues, and stranded messages that must be processed manually. You can avoid these problems by using the options in this article for integrating WebSphere Application Server and WebSphere MQ clusters.

WebSphere Application Server wsadmin script development using the PyDev plugin for Eclipse
IBM WebSphere Application Server administrators often resort to using a text editor for wsadmin script development based on Jython. However, text editors do not provide language-specific support for Jython. PyDev is a plugin for Eclipse that is specifically tailored to Python and Jython program development. PyDev has the usual language-specific features you expect in an integrated development environment (IDE) to enhance your Jython scripting productivity. The PyDev plugin needs some special configuration to support the specifics of wsadmin scripting. This article describes how to configure the PyDev plugin for Eclipse specifically for Jython and wsadmin scripting. The PyDev capabilities will improve your wsadmin scripting productivity by cutting down on errors, such as improper indenting, incorrect syntax, and undefined variable usage.

Innovations within reach: Using WebSphere eXtreme Scale to enhance WebSphere Portal and IBM Web Content Manager performance
IBM Web Content Manager in IBM WebSphere Portal can make use of dynacache instances to store rendered content retrieved from Web Content Manager when advanced caching is enabled. This caching improves response time and reduces load on the database. WebSphere eXtreme Scale and the XC10 caching appliance offers an implementation of dynacache that stores cached content in an elastic data grid instead of using the default dynacache implementation, which stores cached content in IBM WebSphere Application Server heap space or on disk. This article examines the significant performance benefits of moving the WebSphere Portal advanced cache content into a data grid hosted by an XC10 caching appliance without requiring any application code changes.

Comment lines: Using an adapter service pattern to build a more flexible, low maintenance ESB
Integrating multiple systems in a point to point manner can be very time consuming and expensive to maintain. One common approach to resolve this issue is to introduce an Enterprise Service Bus (ESB), which replaces the point to point approach with a single, centralized place to integrate systems, and does so in a service-oriented manner. However, if done incorrectly, this can still create maintenance headaches. Here is a look at a pattern that can “future proof” your integration work, allowing for the upgrading or replacement of legacy systems without excessive additional integration work.
