Session:@\Research Techniques: How To find the right function (the Document
Examiner and beyond) 

Time:@\Thurs. 2 - 3:30

Room:@\McCullough 128

Overview:@\@begin(multiple)This seminar is for users who need to maintain locally-defined
systems, or anyone who enjoys browsing Genera for examples, comments and
internal features.  If you have enough disk-space for system source files and
a who-calls database, this is the place to bring your favorite variations on
the Find Symbol/Edit Definition/List Callers cycle.

Document Hunt:  "Research Techniques" begins with the Document Examiner: its history, 
internal structure, intelligent Candidate selection and Viewer management.  There will 
also be an overview of DocEx performance issues, favorite feature-requests, known problems 
and workarounds.

Exploring Source:  The majority of the seminar starts where the Document Examiner leaves off, 
examining a wide range of Zmacs tools, techniques and private hacks for the study of large 
systems.  Many users rely on a small repertoire of Find/Edit/List/Show commands, unaware of 
obscure keywords, numeric args and extended commands that can make their work easier.

Odds And Ends:  The last third of our session covers miscellaneous topics such as Debug 
Flags, Completion and the Presentation Inspector.  We'll also touch on debugging strategies 
(Breakpoints, string-searches and monitored locations) without actually overlapping any 
material from Brad Miller's Advanced Debugging seminar, and conclude the forum with a 
phrasebook for parsing developers' source-code comments.

Participants:@\Rick Munoz @i(Corporate Support, Symbolics Inc)

Chair:@\Steve Trever @i(Software Support, Symbolics Inc)
Session:@\Databases: Real World encounters with Object-oriented
Database Applications

Time:@\Thurs. 2 - 3:30

Room:@\Skilling Auditorium

Overview:@\Format: Five brief presentations will be given reflecting on the current
state of user experiences with Statice and other object-oriented
database systems.  The presentations will be used to illustrate
conceptual and real world implementation issues that challenge database
designers.  The objective of the session is to answer both hard
technical how-to questions and to raise even harder theoretical issues
such as ontology of object systems.

Robert D. Pfeiffer (RDP@@ALAN.kahuna.decnet.lockheed.com)
"Case study: Statice vs. Real World User Expectations"
Mr. Pfeiffer will focus the integration of Statice and CLOS.  His
investigation was carried out in the context of building a portable
application requering database support.  He will discuss advantages and
disadvantages of the database vs. file system approach, and analyse
application portability and real world delivery requirements.  Lastly,
he will reflect on the idea of what a "turn key" or "portable" yet CLOS
compatible oo-dbms might be like.

Mamoru Sato (forwarded via: ida@@cc.aoyama.ac.jp) "Experiences of the S-system
as a Graphical Object Server for Multi-Media Distributed DBs" Mr. Sato will
present a video of his current system.  It is a book retrieval tool which
provides realistic vision experience as if the user was "Browsing in a Room".
The system was built using Symbolics S-system in a Lisp-Unix environment.
He will then analyse his experience and discuss what are his expectations of a
(graphical) object servers next and how Statice could or should fill that

Howard Schrobe (hes@@STONY-BROOK.SCRC.Symbolics.COM)
@i(Symbolics, MIT) Mr. Schrobe is on the staff of Symbolics and Professor of
Computer Science, MIT.  He has been involved with Statice since its inception;
he will discuss Statice from a technical perspective.

Reza Seddigh (no e-mail)
@i(Natural Selection Associates)
"Real experiences with Flavors to G-Base conversion and a brief
overview of the commercial ORION (tm) oo-dbms."
Mr. Sedding is currently a consultant converting a commercially
available interactive application to run over an OO-DBMS, viz. G-Base.
He will discuss file system vs. dbms implementation of the application.
His talk will address issues encountered in the ongoing project of
conversion from a Flavors-file based model to using G-Base.

@begin(multiple)Tom Shepard (no e-mail)
@i(Houston Lighting & Power)
"Flexibility in Application Delivery:  One Year of OODB
Experience in a Power Company Maintenance Management."
Since March of 1989, Houston Lighting & Power has used a Statice
database containing information merged from two mainframe databases, and
cached on both a daily and demand basis.  The Statice application
interprets the raw data and synthesizes richer semantic structures than
those available on the mainframe.  The database is populated with about
250,000 instances of 10 entity-types and 50 attributes.

He has found that flexibility of the Statice database schema and the
overall productivity of the Symbolics environment, permits rapid
development of applications in the face of changing requirements and
ad-hoc requests involving complex queries.

Leslie A. Walko (attila@@bellcore.com)
@i(Database and Systems Group, Bell Communications Research)
"Design of a very large GIS application using Statice"
During the last three years, Bellcore has built a very large
experimental system in a Semantic DBMS.  Part of that system is being
re-implemented in Statice.  The parallel implementation anables direct
comparison of the semantic and object-oriented paradigms.

Mr. Walko will discuss the conceptual differences between relational,
semantic and object-oriented databases and how such differences impact
functionality.  He will compare Statice and SIM data manipulation
language, comment on performance issues, and overall functionality.

Lastly he will consider, what in general is required for in "industrial
strength" object-oriented dbms; in other words, what's needed so that
the "corporate non-high tech" customer pays money to have oo-dbms

Session:@\Performance: Pitfalls and Tuning

Time:@\Fri. 2 - 3:30

Room:@\McCullough 127

Overview:@\Performance issues are often what determine the success or failure of an
application (and the tolerance of the developer in building the
application).  There have been a number of cases where the application has
had a wonderful set of features, but has failed, because it was too slow to
use.  There have even been a few cases of this with Genera itself!  Most
often performance bottlenecks become significant in interactive systems,
but for large computational tasks (e.g., theorem proving), a few
performance problems can make a manageable problem infeasible.  This
session will cover some of the tools and techniques available, with two
presentations followed by an open Q&A with the participants.

Case study of how Ken was able to increase the overall speed of his
machine by up to 10%, noticably improving the responsiveness of the
interface in 7.2.  May also cover optimization techniques for numeric
operations.  Ken and Dan have designed a wide variety of Lisp systems at

Michael Greenwald <MichaelG@@cs.stanford.edu> - @i(Symbolic Computing Consultants)@\
Why Metering is Hard, and How we can Make It Better, but not Easier.
This is a Good News/Bad News talk.  The bad news is that it is easy to
misunderstand metering results - making the results of the metering
not useful - and difficult to get results that tell you things you need
to know.  Examples of a few common pitfalls will be provided.
The Good News is that metering is still useful, and I'll provide some
guidelines for how to get the most out of metering.
Mike was a developer at Symbolics for about 5 years, working on (among other things)
performance and performance tools, the new scheduler, and was involved in
the port of Genera from the 36xx to Ivory.
