GENERAL NEWS


Management Overview of Computer Centre
(This is a reprint of an article written by the Director of the Computer
Centre for the University Bulletin Issue No:320 Jan 1996)



Preamble

The Registry has kindly asked me to provide some articles for the Bulletin on what Computer Centre does. I value this opportunity to do some advertisement for the Centre, although there is little doubt that the Computer
Centre should be well known to all staff of the University these days, when
the Internet and the World-Wide-Web are such hot topics around the world. If
you are not yet using electronic mail, browsing over the Web or surfing the
Net, then you should take some time to come visit Computer Centre . You
probably don't know what you are missing!

This article is intended to serve as an introduction to the mission of the
Computer Centre , with brief description of our management structure and some
of the recent notable developments of Computer Centre . My colleagues will
provide additional details on some interesting topics in subsequent issues.


Introduction to Computer Centre

Computer Centre provides a wide spectrum of computer and networking
services to the University community at large, including the undergraduates,
the postgraduates, the academics and the administration. Our University is
now at a stage where just about every staff has access to a computer connected
to the campus network. Office automation is starting to spring around every
corner of the campus. And we have yet to see what this new wave of technology
revolution will bring us ultimately.

Computer Centre can boast to be the office with the longest serving hours
in the University (except may be the security guards, I guess). Yes, our
central operations are open 140 hours a week during the academic year, and our
operation staff works on a 3-1/2 shift-rotation. Indeed, even when the Centre
is un-manned, our computers and network are not closed. Our users do expect
the computer servers and network to be up and running non-stop 365 x 24 hours
throughout the year. Our systems are not yet fail-safe and fault-tolerant,
but this is the ultimate aim of the computer services that we would like to
provide.


Mission of Computer Centre

Our mission is to provide a modern and sophisticated information technology
environment in the University to facilitate access and exchange of information
over the Internet and the World Wide Web, the sharing of computer resources
over the campus network, and to enable the University to use the computer and
network resources to effectively and efficiently support teaching, learning,
research and administration.


Organizational structure of Computer Centre

Computer Centre is divided into four major groups, viz, the Centre's
office, the administrative support group, the academic support group and the
operation and maintenance group. Within each group, there are smaller teams
with specific roles to play.

However, our diversified services under limited manpower resources often
required our staff to be multi-disciplinary and multi-tasking, so don't be
surprised if you should find many of our staff to be working in more than one
team/group at any one time.


The Centre's Office

The Director of Computer Centre , Ng Nam, is assisted by the Deputy
Director, P T Ho, in the administration of the Centre with over 80 staff, and
supported by Anita Chan, Administrative Assistant, Idy Tang, Executive Officer
and Judy Kong, Senior Secretary. The Director is responsible for formulating
the strategies and setting the direction for the development of the Centre and
information technologies. He also monitors the operations of the Centre to
ensure that good service quality is maintained.

The Deputy Director is responsible for the day-to-day operation of all our
computers and networks. P T Ho manages the academic support group as well as
the operation and maintenance group. He is in particular responsible for the
development of the campus network for the last few years, which has become a
very important element in our services.

Also assisting the Director is our System Analyst David Carthy. David is
responsible for coordinating the various teams of our administrative support
group, and in setting the standards for migrating our legacy administrative
system to a modern relational database system. He is also in charge of our
office at the Prince Philip Dental Hospital, where the Dental Patient system
of the Faculty of Dentistry is housed.


Inter-institutional cooperation

The Director also plays a leading role in fostering inter-institutional
cooperation among the UGC institution Information Technology Servicess. He has been the
Chairman of the JUCC (Joint Universities Computer Centre) Steering Committee
and the JUCC Director for over five years. This cooperation is very important
in providing efficient inter-campus networking and in sharing our Internet
cost and resources, site licensing of software, joint tendering and purchase
of hardware, software and consumables and other joint projects. JUCC has also
been successful recently in obtaining from UGC an $18 million grant to cover
the three-year cost of the Internet T1 (1.544 Mbps) link to USA. He is
assisted by P T Ho and Anita Chan in the JUCC activities.


The Administrative Support Group

This Administrative Support Group is responsible for the planning,
development, implementation and maintenance of computer applications for the
central administrative offices to facilitate their daily operation and to
provide data and information for the University management. These include
such areas as financial accounting, personnel, payroll, student admission,
student records for undergraduates and postgraduates, research records, space
management, etc. The key administrative offices supported by this group
include the Registry, Finance Office, Estates Office, Office of Student
Affairs and School of Research Studies.

Computer Centre has been busy in the last three years in migrating the
legacy administrative system to a modern relational database system. This has
been a lengthy and slow process, but the conversion is now near completion.
Many of the rejuvenated administrative systems are now online. We are further
improving the access to data and information and is building the new
University Information System with a client-server approach. This will
provide a user-friendly interface to access University information, and is
intended to serve not just the central administration but will be extended to
department and faculty offices and also to individual staff members as well.

We are also providing support to the administrative office in making use of
the latest technology such as the World-Wide-Web (WWW), in helping them to set
up homepages for their offices as well as all departments and faculties, and
dissemination of University information.

Margaret Chung, Senior Computer Officer I, is mainly responsible for
supporting the Headquarters, the Staffing Section and the Development Services
Section of the Registry. In particular, she is responsible for developing the
personnel system and she has started to define the standards for the
redevelopment of the University Information System based on client-server
technology and the use of WWW technology for advertisement of employment
opportunities. Her team also provides support to the Vice-Chancellor's
Office, the Estates Office and the Safety Office.

S Y Leung, Senior Computer II, previously supporting the Academic and Faculty
Services Section (AFSS) of the Registry, has now shifted to support, under the
coordination of David Carthy, the Research Services Section and the School of
Research Studies. The main applications being developed include research
publications, research grants, conference grants and research studentship.
Many of his duties for supporting the AFSS is now taken up by M F Yau,
Computer Officer. The main applications for the AFSS include admission,
classroom and examination time-tabling, transcripts, and the new student card
based on magnetic card technology. Indeed we have also taken up to evaluate
smart card technology for access control and financial transactions.

The Finance Office is currently supported by two teams of the administrative
support group. One is led by W C Ying, Chief Programmer (equivalent to Senior
Computer Officer I). He is mainly responsible for supporting the ledger and
the creditors subsystems and he has also recently taken up to lead a team of
programmers for integrating the Finance Office systems as part of the overall
Integrated Administrative System that was started under the initiative of the
Vice-Chancellor.

Another team serving the Finance Office is led by Anthony KK Ha, Senior
Computer Officer II. Anthony is mainly responsible for the staff accounts
system, which is a complex system for handling all financial matters related
to staff, including payroll, superannuation, loans, etc. His team is also
responsible for student accounts, debtors accounts and inventory. Members of
these two teams also support the computer system of the Faculty of Dentistry
under supervision of David Carthy.


The Academic Support Group

The name of the Academic Support Group is probably a misnomer. Indeed,
anything that does not fall within the Administrative Support Group is charged
under the Academic Support Group. It is not feasible to name all the areas
covered here, but the major teams include systems support, user support, PC
and network support, library system support, supercomputer support,
information server support, application development and office automation.
There is often little demarcation between the teams as many of the areas are
so inter-related. Many of our staff often work in a few areas at the same
time.

The Academic Support Group is responsible for the planning and provision of
computers and networks to the academic community in the University. It has a
very important task of identifying the most cost-effective solutions for the
transfer of the latest information technology to the University to support
teaching, learning and research. Building and maintaining a fast network
together with efficient compute and information servers is the fundamental
requirement of a good modern Computer Centre . The rapid development of
Internet and WWW has created a lot of demand of our resources. The number of
our student accounts is now well over 10,000. All these relies on the
efficient and effective support of the Academic Support Group.

The Systems Support Team and the User Support Team are supervised by Tony C M
Mak, Senior Computer Officer I. The systems support team, currently led by T
Y Kan, Computer Officer, maintains over 20 computer servers in our computer
room, including the administrative systems, the University Information System,
systems for staff and students, library system, supercomputer system and a
large information server. The User Support Team provides consultation at the
Help Desk, telephone enquiries, electronic mail enquiries (CCBOX) and answer
questions and issues raised at the electronic bulletin-board forum of the
Computer Centre . S L Lee, Senior Computer Officer II, is responsible for the
training programmes on computer and network that we offer to staff and
students and on the handbook and manuals that we develop. He also carries the
special responsibility of being the database administrator for the
administrative systems.

M C Pong, Senior Computer Officer I, manages the PC and Network team, the
Information Server team and the Application Development team. The PC and
Network team, currently led by T Y Shen, is responsible for the installation
of PCs for the departments as well as the central and faculty-based
laboratories for the students. This team is also responsible for the
evaluation of network equipment and implements the network requirements in the
campus. We are also gearing up to cope with demand for dial-up access to the
network from home and student halls.

The campus now has a robust FDDI backbone with a gigaswitch serving all
departments in the main campus. The remote sites at the Queen Mary Hospital
compound, the Sasoon Road compound and the Prince Philip Dental Hospital
compound are connected by 512 kbps lines. Plans are on hand to upgrade these
lines to T1 speed. The rapid increase in the number of new buildings, coupled
with the subsequent moves of departments to the vacated space, has demanded a
lot of our manpower resources for carrying out the network connection tasks.
The Estates Office has been most helpful in putting up all the cabling for us.

The Information Server team and the Application Development team are
responsible for the provision of information service. It also provides
assistance to departments and faculties for the use of WWW. New information
dissemination techniques including those of JAVA technology, multimedia
technology, video-conferencing technology and virtual reality technology are
being studied for implementation by these two teams. Peter Leung, Computer
Officer, has been specially assigned to help with any users with an interest
in developing their homepages on WWW.

W K Kwan, Senior Computer Officer II, is responsible for our Supercomputer
team. The University has recently upgraded our supercomputer to an IBM SP2
with 32 RS6000 processor capable of delivering a maximum of 8GFLOPS (8
trillions of floating point operations per second). This is a very valuable
addition to our compute server resources. W K Kwan and his team are to
identify possible research applications on this system and to assist our
researchers who have interest in high-speed parallel computing.

Fanny Chau, Senior Computer Officer II, leads the Office Automation team in
identifying suitable technologies and applications for our future office
automation development. Her team has successfully implemented a client-server
based system which provides for application and enquiry of annual leave from
staff members and for the head of the department to approve the applications
through the University Information System. Her team will continue to examine
new technologies which render effective solutions to our office needs in the
University.

Newton Lui, Computer Officer, provides support for the library automation
system. The Library has recently embarked on a migration of their current DRA
library system to a new Innopac system which will handle both English and
Chinese book titles. Computer Centre has been working closely with the
Library on this project and the installation is well underway. It is expected
that the conversion will be completed in a year's time.


The Operation and Maintenance Group

The Operations team is managed by Stephen Wong, Computer Officer. His team
works the longest hours to support all the computer and network operation, and
aims to provide non-stop service to all our staff and students. It also acts
as the front end for enquiries on system availability and associated hardware
problems. This team is also responsible for the network cabling work and the
installation of network connections. A separate team also supports the
operation of the Dental Patient systems of the Faculty of Dentistry located at
the Prince Philip Dental Hospital.

The maintenance team is generally led by our Technician Wong Chi Man. This
team is responsible for PC maintenance, and the installation and maintenance
of network equipment.


Final Remarks

It is only possible to give a summary overview of the areas covered by our
various groups and teams. If readers should find any area of interest to them
but not mentioned here, you are most welcome to contact the Director or Deputy
Director for further enquiries, or indeed questions can always be directed to
Tony Mak of the User Support team.

I have tried to give a brief overview of the mission of Computer Centre ,
the management structure and the service areas covered by Computer Centre .
It is by no means a complete document of the activities that we do. We have
exciting projects on hand which should be of much interest to our readers. My
colleagues will be providing additional articles on "The HKU Campus Network",
"HKU information services through the Internet and WWW" and on "The University
Information System" in the coming issues of the Bulletin.

The University Information System (UIS)

What is UIS?

The new University Information System (UIS) is an online window-based system
for access to University information. It is a client-server based system
built with user-friendly Graphical User Interface (GUI) to facilitate user
access. The system will be accessible by the central administrative offices as
well as the departmental offices initially, with plans to extend it to staff
and student access in the future. The system serves as a replacement of the
existing UIS on HKUVM1.

In accordance with the administrative structure of the University, the
University information can be grouped into the following categories, namely:
finance, student, staff, research and facilities.These data are separately
administered by the Finance Office, the Academic Services Section, the
Staffing Section and the Research Services Section of the Registry and the
Estates Office.

The administrative applications are primarily designed for use by the related
offices to support their daily operations. Each office is responsible for the
collection, updating and maintenance of the necessary data. The data thus
collected can also be made available to other offices and departments, with
the consent of the originating office. Very often, the information so
requested is distributed to departments in the form of computer listings.

Under the new UIS, information that was previously distributed on paper will
be made available for retrieval directly through PCs connected to the campus
network. The information thus provided is the latest information held in the
database. It can be viewed from the PC screen and if a hardcopy is still
required, it can be printed directly onto one's own printer. Tight control of
information access is also implemented to ensure that users can only have
access to information that they are entitled to and no more.


What is available on UIS

The current version of the new UIS consists of the departmental financial
statement, personnel information, course enrollment, JUPAS admission,
committee membership and the annual leave system. For detail of each
subsystem, please refer to document or online help on each individual system.


How to Apply as a UIS user

To apply for the University Information System, it is necessary for the staff
to fill in an application form to apply for the use of the system. The
application forms are available from the General Office of Computer Centre
(Room 223, Run Run Shaw Bldg.) (tel. no. 2859-2495).


How to invoke the system

To use the system, a user must have access to a PC connected to the Central
Network of the Campus. It can be launched through HKUWIN or server Windows in
HKUMENU.

The icon of the UIS system can be found inside the program group named HKUWIN:
Central Network Service. On double clicking the icon, the UIS system will
launch and prompt user to login. The user must enter the username and
password as instructed before proceeding. (Users who have previously login the
UIS using their staff number instead of a username should re-apply as a UIS
user, as the login using one's staff number would expire by the end of June,
1996)


Hardware requirement for the UIS system

The UIS system is only accessible to University offices and departments
connected to one of the local area networks supported by Computer Centre .
The minimum requirement for running the system is a PC 486 with 8 Mbytes RAM
but Pentium PCs with 16 Mbytes RAM will give more acceptable performance.

Change Password

The UIS username and password is your identification and key to the system.
As important information is accessible from the UIS, users of the UIS system
are reminded that they should keep their username and password well protected
to prevent any illegal access. It is advisable to change the password after
first logging into the system, and also at regular time intervals to prevent
hackers from breaking into the system. Do not choose trivial passwords like
your identify number, telephone number or simple words. Combinations of
letters and special characters will be a good choice for passwords.

If you want to change your UIS access password,

1. Press the Change Password icon, the Change Password window will appear.
2. Enter your old UIS password.
3. Enter your new UIS password twice.
Note : Passwords typed in will be displayed as asterisk (*) for security
reason.
4. Press OK to confirm or Exit to abort.

If you have forgotten your password, you must fill in a 'Change Password' form
and bring it to Computer Centre in person for personal identification.

Future enhancement

The first release of the UIS system will be available to the central
administrative offices and the department heads only. If the system should
run well as anticipated, it will be extended to individual staff in the next
few months. Other subsystems of the UIS are currently under development and
testing, and these will be included in later releases of the UIS. Information
planned for inclusion are staff personal financial information, long leave,
department spending plan and room data information.

The University Information System will be continually enhanced and improved as
we gather feedback from users. We welcome your comments and suggestions which
will certainly help us build a better UIS. Comments or suggestions can be
sent to the administrative office concerned or to Computer Centre .

Telephone Hotline

Your feedback is our success. Please contact Computer Centre at 2859-2491
for any enquiries and suggestions.

More Dial-up Lines

We are pleased to announce that with the help of the Estates Office in
providing us additional telephone lines to the University's PABX, 20
additional night-service (6:00 p.m. to 8:00 a.m) dial-up lines have recently
been set up and are put into service for access by to all members of the
University, including staff and students. These new dial-up lines are set up
as a new modem pool with the dial-up number 28578650. It supports both
HKUPPP and HKUDIAL sessions using V.34 modems (for the maximum data speed of
28.8kbps). Like all other dial-up lines supporting HKUPPP, the session time
limit of this new pool of modems is set to 60 minutes. During the less busy
time when the line utilization of the modem pool is low, the session time will
be extended automatically in steps of 60 minutes.

We are also pleased to announce that the number of lines for the staff-only
dial-up modem pool (i.e. dialup number 28030202) have been increased from 20
to 40. These 40 lines are accessible all the times and support both HKUPPP
and HKUDIAL sessions.

With these newly added lines, the total number of dial-up lines supported by
Computer Centre is increased from 78 to 118, and our users should find it
easier in gaining access to Centre's dailup facilities than before. The
updated dial-up facilities are summarised as follows :

Dial-up Modem Pool NoNo of LinesSession SupportedAvailability

Simplified Scheme for Staff Email Addresses

For many years, a user's email address (i.e. <username>@<nodename>.hku.hk)
includes the nodename of the host computer on which the user's email messages
are sent and received. When another host computer is used for email, the user
has to change to use a new email address which should inherit the nodename of
the new host computer being used (e.g. HKUCC, HKUVM1). Such nodename
dependency of email addresses would be quite inconvenient to users,
particularly to those who have to change to use another computer for email
processing, say, when an old system is retiring from service.

With the set up of the mail server "MAIL.HKU.HK" on the Centre's Information
Server system, we are pleased to introduce the use of a simplified email
address scheme which is independent of the nodename. The format of the newly
introduced email address is <username>@hku.hk. Initially, staff users who
have accounts on the HKUCC or HKUSUA/HKUSUB systems can use the new scheme of
email addresses.

For users who have accounts on the HKUCC system, their email addresses in the
format of <username>@hku.hk are equivalent to <username>@hkucc.hku.hk. For
those who have accounts on HKUSUA/HKUSUB, but not on HKUCC, their email
addresses in the format of <username>@hku.hk are equivalent to
<username>@hkusua.hku.hk. Staff users of the HKUCC and HKUSUA/HKUSUB systems
can still use their existing email addresses (i.e.
<username>@<nodename>.hku.hk) in their electronic communication. However,
they are encouraged to inform their communication peers to use their new email
addresses (i.e. <username>@hku.hk).

Eudora users can set their outgoing emails with the new email address formats
by re-configuring the Eudora settings, as follows:

1. Change the SMTP Server setting from "hostname.hku.hk" to "mail.hku.hk"

2. Change the Return Address setting from "<your-username>@hostname.hku.hk"
to "<your-uername>@hku.hk".

At present, the new scheme of email address applies only to staff users of the
HKUCC, HKUSUA and HKSUB systems according to the above described email address
equivalence. Staff users who require to change their email address
equivalence can apply for the change by completing the "Application for Change
Email Address Equivalence" form obtainable from Centre's General Office in
Room 223, Run Run Shaw Building.

For further enquiries about the simplified email address scheme, please
contact the undersigned.

Netscape News Server put into service

We are pleased to announce that in mid-April, we have installed the Netscape
News Server software to replace the C-news software on our central News Server
NEWS.HKU.HK. This upgrade has solved the incompatibility problem between the
old News server software, C-news, for the NEWS.HKU.HK and the "ANU-News" News
client software running on HKUCC. Previously, users on HKUCC could only
access to News bulletin board through a separate News server running on the
HKUXB system which can keep only a much smaller number of the News articles
due to disk storage limitation. At present, our users can gain access to over
17,000 newsgroups mounted on NEWS.HKU.HK through either the central server
systems, including the HKUCC, HKUSUA, HKUSUB, HKUXA, HKUXB, HKURSC and HKUSGA,
or PCs connected to the Campus Network. The News server running on HKUXB is
still maintained to serve as a backup News server.

Annual Account Renewal and Deletion

All staff and students of the University are eligible to have one general user
account on one of Computer Centre's academic host computers, e.g. HKUCC or
HKUSUA, during their stay in the University. The computer budget for all
general user accounts will be reset to their standard allocation value on
September 1 each year only if the users remain as members of the University in
the new academic year. The standard budget allocation for staff and
postgraduate students is $5,000 and that for undergraduate students is
$2,000.

All users are therefore reminded that if they will leave the University soon
or change their status from undergraduate to postgraduate students, from
students to staff or vice versa, they should take steps to back up their
useful files in advance of the change. This is particular important for users
who are changing their status from student to staff or vice versa because new
usernames will be allocated under their new status and the username (together
with their files) registered under their old status will not be accessible
thereafter.

Users leaving the University are reminded that their accounts and files on the
academic host computers will be deleted. They are thus advised to backup
their useful files on tapes, diskettes or other backup media well before their
accounts are deleted. The account deletion arrangements are as follows :

1. All accounts and files of undergraduate students who are graduating in 1996
will be deleted on September 1, 1996

2. General computer accounts are granted to staff and students of the
University only if their names appear on the Registry's database. When
their names disappear from the database, their general computer accounts
will be removed without further notice.

3. Course accounts and their data created for the last academic year (i.e.
1995-96) will be deleted on September 1, 1996.

4. Special accounts which are not renewed before October 31, 1996 will be
deleted in November 1996. This categories of accounts include
departmental/group/production accounts, consultancy accounts and guest
accounts for visiting scholars and fellows. Renewal notices of these
accounts will be sent out in early September 1996 and users should ensure
that their accounts are renewed in time to avoid any inconvenience.

If you have any queries on the account deletion and renewal process, please
contact the undersigned.

Termination of Bitnet Service

The Bitnet link to the Yale University will be terminated by end of June, 1996
as the Yale University has decided to wind down the support for the Bitnet
connection. (Indeed, BITNIC has decided that Bitnet services will be
terminated by the end of 1996.)

The Bitnet connection to the Yale University was established 7 years ago.
With this connection, members of the University were able to communicate with
other overseas institutions and organisations that were also connected to the
Bitnet. Electronic mails and Mailing lists (i.e. LISTSERV) were the two major
use of Bitnet since its establishment.

Since our connection to Internet, we have been adopting the Internet address
format, i.e. username@hostname.hku.hk for electronic communication in last few
years. However, users who are still replying on Bitnet for electronic
communication are strongly advised to change their Bitnet address format
(i.e. username@hostname.bitnet) to the Internet address format (i.e.
username@hostname.hku.hk) and to notify their communication peers of such
changes accordingly before the Bitnet service is terminated on June 30, 1996.

To cater for the termination of Bitnet service, we have recently changed the
provision of our mailing list service (i.e. LISTSERV) from Bitnet connection
to Internet connection. This change should not affect users who have
subscribed to the LISTSERV mailing lists.

Bitnet has served as a very important email and network services for us in the
last 7 years. Though it has come to a logical end, it has played an important
role in the history of our development of network services. We take this
opportunity to thank the Yale University for their support on Bitnet services
for all the academic institutions in Hong Kong and, in particular, to our
University.
