This session describes the current status of MQSeries, its technical development, and installed base. It describes the primary uses for message queuing. Mr. Osborne identifies current platforms covered by MQSeries, the key issues in heterogeneous integration, and how IBM works collaboratively with partners to create a range of add-on capabilities to the robust message queuing core. Learn what message queuing is used for and how it relates to other connectivity middleware. Attendees gain insight on technical trends and the directions in which MQSeries is moving.
Enterprises have used CICS for decades to create mission-critical transaction applications. The transaction applications that are running businesses today have been steeled through years of stress-testing and improvement. Why rewrite those transactional applications for the networked environment when they can simply be extended to the Web using VisualAge for Java? This session explains how to build business solutions into a Web site and increase the return on an investment in CICS.
Mr. Asselin offers an introduction of the API that allows applications to run on a TCP/IP network. Attendees learn the basics, including TCP vs. UDP, ports, connecting to a server, sending data, and error handling, and then the focus moves to more advanced topics. The session teaches how to write a TCP/IP server, multithreading, non-blocking sockets, select ( ), setting socket options and porting from Unix.
Due to powerful connectivity features and wide platform coverage, asynchronous messaging and queuing (M&Q) products have become a very popular form of application-to-application communication. Yet, there are still many cases when a synchronous remote procedure call (RPC) model is the appropriate choice. More importantly, most enterprises will eventually need to use both techniques. This session describes the principles behind both models, contrasts their use, and provides a number of guidelines for selecting the best technology for a given application.
MQSeries has become a well accepted technology in businesses large and small, and across every industry. Today there are over 2,500 companies using MQSeries in many different ways. This presentation surveys a number of MQSeries production applications, discusses how MQ is being used and why MQ was chosen. Examples include basic data distribution and some of the more obscure, but clever, MQ applications are described.
The use of the World Wide Web in Internet and intranet applications continues to grow exponentially and many companies now find themselves needing to integrate existing applications and data with the Web-based interfaces. This session discusses how companies can use Transarc's Encina product, combined with a Java-based client interface, to build secure, scalable, and manageable applications that are easily accessible from popular browsers. These applications can interact with popular RBDMS systems, message and queuing products, and existing mainframe applications. Attendees also learn how the Distributed File System (DFS) component of DCE can be used by Web sites to increase scalability and performance, and to reduce maintenance costs.
Mr. Meaders presents an approach for Rapid Development of CICS Family Transaction Server Applications, and associated Text, Graphical, HTML Browser, and Java Browser User Interfaces, using tools which are currently available. Attendees benefit from seeing the approach demonstrated from start to finish on a simple database maintenance application.
The Network Computing model, which features thin clients and powerful servers, becomes more practical when applications are provided with high availability and scalability characteristics. Mr. Kalka presents an overview of clustering as well as today's current clustering options. Attendees learn how application clustering helps network computing and hear customer examples which demonstrate the value and benefits realized by the organizations that use it.
