Article by Bernd Widmer and Wolfgang Lugmayr evaluated three tools that focus on management of distributed applications based on the Orbix C++ CORBA implementation: Orbix Manager, Corba Assistant and Object/Observer and investigated the capabilities of these tools and identified the benefits and shortcomings of these according to criteria such as overhead, ease of instrumentation, management configuration capabilities and integration with standard management frameworks. Abstract. Full text in postscript file.

Discusses the issues raised by, and choices available for bootstrapping a CORBA application so that each of the processes may access the services of its peer processes. Describes the options for developers and considers the performance, and reliability/fault tolerance tradeoffs of each of the techniques.

Introduces caching solutions for improving availability and predictability of distributed services. Cascade (caching service for CORBA distributed objects) facilitates scalable application design by building cache hierarchies for the objects it manages.

Takes a look at how to extend the functionality of an open-source program without actually changing the source code.

Explains how to use COSNotification Service and points out the advantages over the COSEvent Service. Covers structured events, filters, and Quality of Service issues.

Takes a look at the relationship between XML and CORBA and explores the topic of versioning.

Discusses various alternatives of passing XML-defined data between client and server. Concludes with a brief discussion of SOAP and Web Services and how they relate to CORBA.

Compares SOAP and IIOP and then concludes that Web services and CORBA are not rivals, but instead are complementary.

Outlines upcoming changes to the CORBA specification, and explains what it means for current and future projects, and interoperability with other component models.

Describes CORBA Portable Interceptors, which are objects that an ORB invokes in the path of an operation invocation to monitor or modify the behavior of the invocation transparently.

Covers existing CORBA CosEvent services and the enhancements which will be made to them with the introduction of advanced notification services in CORBA 3.0.

Scratches the surface and lays the groundwork for demystifying security as it relates to CORBA middleware.

Article provides information on the background to CORBA, where CORBA can be found today and standards activities. By Charlotte Wales, Fred Waskiewicz.

Focuses on the specifications for middleware-based load balancing mechanisms developed using standard CORBA, and discusses the specific load balancing service we designed using TAO.

Covers the basics of the DII (Dynamic Invocation Interface), the client-side interface used for dynamic CORBA applications.

Explains the Dynamic Any, which is the standard facility for manipulating values of constructed types within Dynamic CORBA applications.

Presents the CORBA DSI (Dynamic Skeleton Interface), which is the server-side counterpart of the CORBA Dynamic Invocation Interface.

Shows how CORBA developers can use the IFR (Interface Repository) to construct truly dynamic applications that discover all necessary type information at run time.

Article on Sun's CORBA strategy shift.

This article explores how some useful extensions to an open-source protocol analyzer in order to allow the extraction of OMG IDL (interface definition language) defined data types from TCP/IP traffic (using GIOP/IIOP) have been added.

This paper discusses the implementation of CASCADE, a distributed caching service for CORBA objects.

Introduces Fault Tolerant CORBA and describe the architecture set forth in the FT CORBA specification.

While there may still be a place for technologies such as RMI, CORBA represents a great threat, and offers great rewards for those Java developers that adopt it.

This article introduces JMS and the CORBA Notification Service and describes the challenges being addressed in providing an interworking solution. By Steve Trythall.

This article explains how to simulate the pass-by-value strategy in CORBA 2.2 using Java so that a client virtual machine can locally invoke methods implemented.

Describes what local objects in CORBA are and why they are required to utilize many advanced CORBA features such as servant managers, portable interceptors, and policies.

This paper investigates performance issues for distributed object systems. Claims that object caching is a must for improved performance and scalability in distributed object systems.

Discusses the C++ language mapping for object references, addresses memory management issues related to object references, and demonstrates the correct means of exchanging object references during CORBA request invocations. This article focuses on object references, the basic pointer (_ptr) type, and rules for exchanging object references during CORBA requests.

This article presents an extension to CORBA to help programmers encapsulate parallel code in distributed objects. This extension, called PaCO (Parallel CORBA Object), hides most of the cumbersome problems associated with parallelism, while still allowing scalable communication between parallel CORBA objects.

Takes a look at the Real-Time CORBA specification that defined several mechanisms to provide for end-to-end deterministic performance for CORBA operations.

Describes how middleware is evolving to support distributed real-time and embedded systems. Focuses on real-time CORBA.

Shows C++ code examples that illustrate how to program the real-time CORBA priority mechanisms.

Describes real-time CORBA's support for thread pools and synchronizers.

Explores features that allow distributed real-time and embedded applications to select protocol properties and to explicitly bind clients to server objects using pre-allocated connections, priority bands, and private connections.

Gives a brief overview of CORBA, then discusses servlets and demonstrates how servlets can communicate with CORBA servers.

Load balancing helps improve system scalability by ensuring that client application requests are distributed and processed equitably across a group of servers. Likewise, it helps improve system dependability by adapting dynamically to system configuration changes that arise from hardware or software failures.

This column is the first in a series that focuses on the CORBA Component Model (CCM). It first outlines the evolution of programming abstractions from subroutines to modules, objects, and components. Then it describes how this evolution has largely been mirrored in middleware, from message passing to remote procedure calls and from distributed objects to component middleware. Finally the article discusses the limitations of distributed object computing (DOC) middleware that motivate the need for component middleware in general and the CORBA Component Model (CCM).

This column discusses a hybrid publisher/subscriber and request/response distribution architecture that uses CCM features to implement stock-quoter example.

This article covers the pitfalls of CORBA.

Explains the low-level protocols used.

Compares CORBA and SOAP. Contains many interesting comments originally made in a thread on the comp.object.corba newsgroup.

Gives an overview of the two technologies and helps determine how best to make them work together.

Shows an alternative approach to supporting reflection in CORBA. The basic approach involves having each object returns its own metadata, rather than relying on an external service, such as the IFR.
