AFS has been in use at Merrill Lynch for over 18 months and currently
supports over 60GB of disk spread over 6 file servers. This talk
describes a solution designed and implemented by Merrill Lynch to
better meet the company's backup needs. The solution uses the
distributed facilities in AFS, a dedicated backup machine with disk, a
tape jukebox, and some scripts (shell and perl). The backup solution
is of simple construction where all normal processing is automated.
The solution will scale up to meet requirements of increased backup
size, increased redundancy or decreased backup windows. Additional
functionality can and will be added as resources are available.
Khat-Kerberos-Based Long Running Jobs in an AFS Authenticated Environment
Peter Honeyman
Associate Research Scientist
University of Michigan
In strong authentication systems, users may obtain access to secure
system resources only when in possession of valid credentials. These
are issued with limited lifetimes; their renewal requires a user to
enter her password. This presentation describes khat, a system
developed at the University of Michigan with which a user may schedule
a batch job to be run at a later date in the current environment. The
batch job is stored on a secure machine and sent and received in
encrypted form. When it is time for the job to run, the server
generates credentials for the originating user and sends them
encrypted to the machine on which the job will run. The user is given
an option to specify that tickets should be continually generated for
the job until its execution has completed.

This talk discusses the use of JAM/TPi as a tool for Encina
development and as an excellent environment for developing business
applications. The presentation also addresses the critical importance
of using proper tools to develop real-world D-OLTP applications. Many
tools are inappropriate because their development models are
inherently inconsistent with open, distributed, and, especially,
transactionally-distributed computing. The appropriate tools must
support rapid application development of both client and server
components.

Generating COBOL Transaction Services for Client/Server OLTP Systems
Ross Altman
Director of Product Management
Magna Software Corporation
Client/server OLTP offers excellent benefits in both price/performance
and functionality. The development of client/server OLTP applications
has been slowed by the lack of tools to generate both client and
server processes. On the client side, an open interface that allows
the client process to be built with any development tool is an ideal
solution. On the server side, a program generator that produces fully
compilable COBOL code provides an equivalent level of flexibility.
This session demonstrates an approach to the development of
client/server OLTP systems that meets these two requirements.
An Administrative GUI Desktop for Encina
Peter Luppi
Chairman
Fusion Systems Group, Inc.
The industry is moving quickly towards graphical front-ends that
support system administration. Fusion Systems Group is working with
Patrol Software to build an iconic "administrative interface" for
Encina. This talk discusses the initial experience in developing the
prototype and the benefits, facilities and trade-offs in interfacing
the GUI front-end to the Encina Monitor environment.
Building Scalable Client/Server Applications Using the Encina Transaction
Monitor and Independence Technologies' iTRAN Toolkit
Daniel J. Carnese
Product Manager
Independence Technologies, Inc.
This talk discusses the implementation of Transarc's Encina monitor
with the iTRAN ToolKit from Independence Technologies, as a unique
mechanism for building scalable client/server applications which
support large numbers of users in a real-time environment. In the
seventies and early eighties, OLTP was performed on large-scale
mainframes running proprietary software. Today, it can be performed on
non-proprietary systems with fast, inexpensive microprocessors. This
significantly reduces the cost of OLTP, which allows existing
applications to run more cheaply and justifies the cost of developing
new applications.

The Evolution of Large Scale, Distributed Computing at North Carolina State
University
Dr. William Willis
Associate Provost for Academic Computing
North Carolina State University
In the Fall of 1989, the College of Engineering at North Carolina
State University began a distributed computing project to provide
computer access to the 7,200 students in the College. Using technology
>From MIT Project Athena combined with AFS from Transarc, the College
installed 200 unix workstations. Despite tight budgets and limited
support personnel, the environment has grown to over 1,200
workstations, with servers and users across the entire University.
Through this experience, NCSU has found unanticipated problems and
benefits. This presentation addresses the experience and discusses
plans to bring the environment to all 34,000 members of the University
community.

C++ with DCE and Encina
Larry Poleshuck
Vice President
Citibank
For the past three years, Citibank has used DCE and Encina in a C++
environment and has put into production a transaction processing
application which uses NCS RPC and C++. Building on this experience,
Citibank has defined infrastructure requirements for the use of C++
with DCE and Encina. This talk describes user experiences and the
class libraries constructed to provide a robust and easy to use
interface. The libraries encapsulate DCE and Encina using C++ syntax
and provide a data definition language that simplifies the use of SFS
and RQS.

DFS Token Manager
Pervaze Akhtar
Area Manager of Distributed File Systems
Transarc Corporation
AFS 3 file servers use "callbacks" to notify clients when a file is
updated, so that those clients may invalidate their caches. DFS
generalizes this notion into a mechanism called the token manager,
which mediates operations performed concurrently by several cache
managers. This presentation addresses the ways in which the token
manager enables DFS to provide closer emulation of distributed UNIX
semantics than any other caching distributed file system.
