Building the Solutions

A Relentless Commitment

As a leading provider of innovative, enterprise-scale distributed systems, Transarc's commitment to quality, technology and customer success is relentless. We give companies from virtually every industry the most complete and comprehensive network computing solutions available to meet their individual business goals quickly and profitably. These solutions include IBM's TXSeries™, which consists of the industry-standard DCE, Encina®, CICS®, DSSeries and a related connectivity tool suite, and the AFS® and DFS™ enterprisefile system products.



Standards like the Distributed Comput-ing Environment (DCE) provide a common infrastructure that helps protect companies' investments as new technologies are integrated into existing systems. A member of the original multi-vendor team whose proposal to the Open Group became the basis for the DCE architecture and much of its technology, Transarc continues to support DCE while we look to the object-oriented future with CORBA-based solutions.


The growing number of companies looking to leverage the Internet and conduct e-business has generated an increased need in the middleware market for solutions that reduce the complexity of developing, executing and administering applications to accomplish just that.

To meet these needs, Transarc products and services have been integrated with IBM's. These products help simplify the development and management of complex applications, primarily in large organizations, and also give many types of system software greater security, easier scalability, simplified systems management, and more commonality of use and administration. The key products within Transaction Systems include TXSeries (for transaction processing offerings), the AFS and DFS enterprise file systems (the basis for enterprise file sharing), MQSeries® (for messaging middleware both as products and via OEMs) and DSSeries (infrastructure family of products).


TXSeries is IBM's complete distributed transaction processing solution. Developed by Transarc, TXSeries provides a combination of integrated technologies for developing, deploying and managing e-business and cross-enterprise transactional systems. These capabilities cross multiple platforms to provide a scalable, robust, flexible, high-performance environment for current and re-engineered applications on any tier of an enterprise network. TXSeries integrates Encina with Distributed CICS, lightweight products like DE-Light Gateway, CICS Gateway for Java, CICS Internet Gateway, required components of DSSeries, MQSeries and the Domino™ Go Webserver, to give customers a comprehensive enterprise solution. TXSeries provides:

  • the capability to build e-business applications that leverage the Internet, protect customers' current investments and provide faster implementation of e-business, and includes a fully Web-enabled application server for e-business.
  • the key functionality needed for customers to build applications that they can depend on.
  • open-systems support for the multiple platforms used by most customers by providing a middleware layer that does not lock them into any particular hardware or operating system.
  • trusted, worldwide support from proven performers such as IBM, Transarc and their business partners.
  • investment protection through application mining that gives new life to customers' existing applications.
  • state-of-the-art technology in object capabilities, enterprise systems management and Internet standards.

TXSeries gives customers a more open, more complete, more powerful and more tested software package that has become the solution-of-choice for businesses relying on results-based transaction systems. These combined resources help customers maintain their competitive edge and demonstrate Transarc's continuing commitment to bring to market products that represent leading-edge technology and strategic positioning.


Encina enables companies seeking industry-leading, enterprise-class distributed computing capabilities to develop and deploy three-tiered applications on a variety of platforms. Encina extends the power of DCE to simplify the construction of reliable distributed systems and provide the integrity guarantees required for business-critical computing.

The simplified security, transactional mainframe connectivity, scalable and resilient three-tiered infrastructure of Encina, as well as its distributed objects support (through Encina++) provide value-added services. Encina gives organizations a network computing environment that not only delivers reliable performance and data integrity, but that also can be tightly controlled.

To expand its object-oriented programming capabilities, Encina supports the Object Management Group's (OMG) Object Transaction Service (OTS) and the Object Concurrency Control Service (OCCS) on top of a commercial Object Request Broker (ORB). This enhanced object support lets users develop C++ clients and servers — as well as Java clients — that work with the Orbix object request broker.

Distributed CICS

CICS or Distributed CICS is an industry-leading family of transaction processing products that enable businesses to exploit applications and data on many different hardware and software platforms. CICS has evolved in response to changing customer needs, and offers excellent support for the client/server paradigm and for the emerging network computing industry. Ideal for large on-line networks, CICS offers application compatibility with platforms like AIX, MVS, OS/2, OS/400, VSE, Windows NT, HP, Digital and Sun. Its robust, open platform supports client/server applications with portability across many platforms; interoperability across LANs and WANs to maintain integrity and dependability; scalability to support systems with users ranging from tens to tens of thousands; and manageability through a single point of control even in complex configurations.

CICS not only supports business-critical client/server applications and migrates existing applications, it also supports workstation integration to mainframe CICS. Its single-system image or single point of control makes system administration and workload management easier. And CICS supports simple to complex multi-user applications, reuse of investment in applications and skills, application, data mobility and management, end-to-end integrity as a system function, and high-volume and high-availability transaction processing. And CICS supports a wide range of client platforms via the CICS Clients.

Connectivity Tools — DE-Light, CICS Java Gateway and CICS Internet Gateway

TXSeries includes some of the industry's leading components for Web-based transaction processing. DE-Light, CICS Gateway for Java and CICS Internet Gateway give customers the capability to blend traditional Web clients with commercial-quality transaction processing systems. DE-Light Gateway is a lightweight middleware that integrates the Encina monitor with Java-based client front ends such as standard Web browsers and Java servlets. CICS Gateway for Java is a powerful solution for accessing the popular, proven transaction capabilities of CICS servers from the Internet. And CICS Internet Gateway allows Internet users to access existing 3270 CICS applications from the Internet. These Web client-to-server connections enable customers to perform Web-based transaction processing with greater reliability, accessibility and flexibility.

Internet DE-Light extends the power and scope of DCE and Encina to the Internet, providing the security and reliability to conduct and support electronic commerce using standard Web browsers, and powerful DCE and Encina services. Built with the Java programming language, Internet DE-Light lets developers leverage Java's benefits to create client applications that are visually consistent across platforms, easier to manage and more portable than ever before while remaining compatible with other DCE and Encina clients, and existing application servers.

CICS Clients

In response to the growing demand for e-business solutions, Transarc offers CICS Clients to provide an ideal mechanism for connecting users, applications and networks. An easy, cost-effective route to full client/server implementation, CICS Clients let you extend those applications currently being used in your enterprise to the rapidly growing numbers of network connected end-users. And when you need to develop new applications, CICS Clients allow you to access the latest tools and techniques while making the best use of your existing hardware, software and workforce skills to enhance productivity, reduce costs and risks, and improve time-to-market savings.

Because CICS Clients support industry standard communications protocols like TCP/IP, APPC, and NetBIOS and IPX/SPX via Novell NetWare, they make it possible to integrate the reliable, scalable and secure enterprise infrastructure of CICS with the networked world. Whether you need to build an industry-level, e-business solution or migrate from a host-based system to a distributed CICS environment, CICS Clients provide the versatility to connect popular client workstations to CICS servers, leading messaging and groupware products like Lotus Domino, or to the Internet.


Whether your workplace is Internet- or intranet-based, Transarc enterprise file systems technology offers unlimited scalability, cluster-computing flexibility and exceptional reliability for global file sharing throughout a client/server environment. Global file sharing allows customers to make existing resources available to a wider user audience across the enterprise. By distributing business-critical information, customers can achieve higher availability, better performance and reduced administration costs. And global file sharing is an ideal solution for users wanting to perform collaborative project development, Web page storage and graphics storage.

The AFS and DFS enterprise file systems establish a single, shared file space for all authorized users from all possible locations — not just specific organizations, locations or machines. These products provide the high performance, scalability and security to ensure that your information remains available, accessible, easy to manage and protected from unauthorized access. Features like replication, client-side or local caching and rigorous security mechanisms not only keep information available during temporary system failures, but also distribute information requests to perform load balancing and prevent system bottlenecks to optimize performance.

Multiple security mechanisms define access privileges to control who has permission to use or update specific information and prevents unauthorized users from gaining access. And the AFS and DFS enterprise file systems are manageable, designed to scale without placing undue burden on your system administrators or adding excessive costs to the overall system.

The AFS and DFS enterprise file systems offer you a range of additional capabilities to meet your enterprise needs. AFS, the original distributed file system developed by Transarc, is designed for medium-sized businesses, large enterprises and large departments within a corporation that need a scalable, high-performance, reliable file sharing system. AFS does not require DCE and provides a simple security and administrative model for file sharing that supports broad platform coverage on Windows NT and UNIX.

For tightly integrated enterprise applications where a standard infrastructure, such as DCE or another DCE-based application like the TXSeries Encina API, Global Sign-On or SnareWorks is of interest, DFS is the ideal solution. DFS supports global enterprises and large organizations with enterprise file sharing across Windows NT, UNIX and OS/390 platforms. It also uses the industry-standard DCE security, naming and RPC for its distributed computing infrastructure.

The DFS Server, for example, offers a complete DFS server environment for customers who need additional platform availability to serve up DFS files not only in UNIX but also in NT environments. The DFS Control Center gives customers a GUI-based single point of administration for performing remote administration of DFS servers running on any platform from a Windows NT management station.

Customers wishing to expand Web access to their enterprise can do so with DFS Web Secure, a feature of DFS that allows users to maintain corporate security levels while expanding access to the enterprise. DFS Web Secure lets authorized users access business-critical information stored in DFS from a standard Web browser while bringing DFS capabilities to either the Internet or corporate intranet environment. Regardless of the environment, Transarc's enterprise file system products have the versatility that allows businesses to function more reliably, efficiently and with greater security than ever before while expanding their enterprise to take advantage of the global market.

Envisioning the Enterprise

A Pioneering Spirit

Nearly 20 years ago, Dr. Alfred Spector and other key Transarc computer scientists envisioned the computing landscape of the 21st century as a maze of multi-platform, distributed information technology systems where users transparently access and process information from any location to support global operations.

That vision began to take shape at Carnegie-Mellon University in Pittsburgh, Pennsylvania where Dr. Spector was a professor of computer science and director of the joint CMU-IBM Information Technology Center. The center's work consisted of two projects: Andrew and Camelot, each representing pioneering research in large-scale, distributed computing environments. These projects led to the formation of Transarc Corporation. Transarc took the research being performed at CMU out of the laboratory and into the commercial sector by developing products such as AFS, DFS and Encina. Today, Transarc is a wholly owned subsidiary of IBM Corporation. Backed by the technical and financial strength of IBM and led by a team of the industry's best and brightest talent, Transarc's achievements continue to set the pace in the race for technology superiority.

As the first company to successfully process one billion transactions in less than 24 hours, Transarc has opened the door to a new level of enterprise computing performance. Its commitment to delivering technically superior products and services gives Transarc the power to help organizations worldwide take the lead in information systems.
