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.

Working with the IBM Rational Change project security feature: Part 1. Introduction and terminology
The project security feature was added to Rational Change in Version 5.3 an alternative to traditional database security, where privileges are statically assigned at the database level. When you enable project security, rather than assigning users static privileges that apply to all change requests (CRs) and tasks within a particular database, users are assigned dynamic privileges within the context of a set of related CRs. This makes user management for Rational Change 5.3 easy. Part 1 of this two-part article explains the feature and the related terms. The purpose of both parts is to make you comfortable with the terms used in the feature before you begin using it and to help you understand and implement the feature easily.

C++0x, scoped enums
This articles introduces the new scoped enums feature from the new C++ standard, C++0x. Scoped enums are meant to help you write more portable and more expressive code. For instance, scoped enums can have an explicit underlying type that improves portability, can be forward declared, and do not undergo any implicit conversions. That enhances type safety. The previous enum behavior still exists and is now referred to as unscoped enum. Unscoped enums are able to inherit some of the functionality of the scoped enums, such as explicit underlying type and forward declaration. This article describes all aspects of scoped enums and provides examples, along with good usage patterns that you might find useful.
