Object and Object-Relational database systems: a growing shift

Craig Linn
School of Computing and IT, UWS Nepean

An increasing number of vendors including IBM and Oracle are extending their existing relational DBMS in order to provide better support for complex objects. The result is an Object-Relational DBMS that is capable of supporting diverse applications, particulary those requiring complex multimedia datatypes. This paper firstly examines what a pure Object-Oriented DBMS is and then compares this with the Object-Relational hybrids that are appearing. A number of issues are examined including:

• how can an organisation benefit from this technology,
• how do these systems perform, and
• how flexible are they in terms of management and system development.

Storage Processors Performance Comparison

Tom Beretvas
Beretvas Performance Consultants

New DASD technology is used in proprietary control units, so-called "storage processors". The paper examines these technologies, such as IBM RVA, EMC Symmetrix, etc. with a view of comparing performance limitations of these processors. Various publicly available performance measurements are used to address the performance limitations. Maximum likely I/O rates achieved are suggested.

Protecting Data under Open Systems Databases

Monish Chopra
StorageTek

UNIX is becoming more stable and many large companies have started deploying mission critical applications on the UNIX platforms.Even NT environment is attracting some small department level applications. This trend is expected to continue. Data Protection of these databases is being ignored for the time being - as IT operations try to do more with less, and focus on more burning issues. Here is a tutorial to explain the various options in simple terms and present a cook book using which you can start developing a strategy for protecting this data. Presentation will cover:

- The current environment

- Hierarchy of Data Availability

- Strategies for implementing greater data protection

- Examples

The Environment - who cares?

Pierre LOUYS

Acknowledgement The materials of this presentation is mainly drawn from the Fuji Xerox publication "down-to-earth officecare - a practical guide to environmental action in the office". ($30) Do we care that... · everyday the world burns an amount of fuel energy that took the earth 10,000 days to produce · municipal waste production in Australia is around 680Kg per person per year of which more than half could be re-cycled · many of our activities are not environmentally sustainable meaning...

1. we use resources faster than they are renewed
2. we cause cumulative degradation to the environment
3. financial bottom lines come at a price to the environment

The environment is a concern for organisations? · 89% of people said they felt environmental protection was as important as economic growth there is a growing recognition of environmental impacts of producing goods and services environmental information is required by managers to measure :

1. risks
2. liabilities and
3. costs associated with business activities

Why would you care? · You do not have to be a "greenie" to appreciate that our world s resources are being depleted. You'd rather be part of the solution not the problem... · Because a common action fosters unity and good attitude in the workplace Down-to-earth toolkits Equipment Lightning Air conditioning Paper EMS and ISO 14000 more information...

3746/900 Tracing and Diagnostics

Will Wharton
William Data Systems

This presentation will look at tracing technologies available to a 3746/900 user and will explore the diagnostics that they contain. Special reference will be made to APPN inc. HPR, Frame relay, Token Ring and X25., showing how and why this information is relevant to the Network Support Staff in diagnosing both network and application problems.

Extending AFP to the Enterprise

Tom Payne
EXECP

IBM's Advanced Function Presentation (AFP) architecture has been often viewed as too costly and complicated to implement enterprise-wide. To further exacerbate the issue, just as AFP has become a standard in many MVS environments, PCL has become the dominant force in laser printers distributed throughout the enterprise. How can these two technologies be integrated, and what benefits can accrue to the enterprise that takes on the challenge of extending AFP to the Enterprise?

Virtual Tape Management Systems - Solution or Problem?

Mitch Mackrory
Storage Tek NZ

Virtual Tape Management Systems are a hot storage topic. They have, on occasion, been presented as the answer to all sorts of storage issues. Certainly they are the answer many age old problems, but they need to be sized and implemented appropriately, and with technical understanding. If they do not do the job properly, senior management may have bought a white elephant and that does nobody any good. Users must ensure that they understand the implications of this new technology before committing to incorrectly sized or engineered equipment. This paper addresses some of the solutions offered in the past, such as tape stacking, and investigates some potential new costs and considerations.

Managing Year 2000 Compliance in a Wired World.

George Sawyer
Novadigm

This paper discusses techniques that assist enterprise customers and organisations with distributed software, to automatically identify, update and manage Year 2000 compliant and non-compliant software applications. These techniques have achieved success in reducing administration overhead by up to 80% and have been able to maintain operational reliability of 99+%, resulting in significant reductions in total cost of ownership and increases in service levels.

Communications for the mobile or remote workforce

Neil Higgins
Energex

"Putting the front line online" is rapidly becoming a business imperative for many service organisations. This paper overviews data communications, media and networks in a mobile context, then explores key issues for ENERGEX - a large, multi-faceted service organisation. The conclusions highlight the need for a comprehensive strategic, tactical and economic planning process.

OS/390 Trends and Directions

Eve Bye
IBM Australia

OS/390 is now 3 years, 2 versions and 5 releases old. What has happened in this time and what is coming in the future?

This presentation covers the new functions introduced in OS/390 2.4 and 2.5 as well as the changes in packaging and delivery. We also take a sneak look at what is coming in OS/390 2.6 (GA Sept 98).

What Did You Do in the War Daddy? Positioning, Planning, and Tuning for Virtual Tape Parts 1 & 2

William Gray
Storage Tek Canada

With reference to the "Three Waves" model of tape processing [GRAY1], we explore tape issues up to the implementation of virtual tape systems which will introduce new complexities for us. So that we do not end up fighting the next war the way we fought the last, we create a methodology that can be used for positioning, planning, and tuning all aspects of tape processing. Using a real case-study, we progress a large tape shop from real to virtual drives. Batch problems are gone but replaced by new challenges for we analysts: cache sizing, backend bandwidth, frontend bandwidth, LRU issues and other items related to running with other tape processes.

The Year 2000: Strategies for Managing Application Performance

Denis Fox
Programart Corporation

The risks associated with the failure to manage application performance during Y2K reengineering efforts include unacceptable response times for business-critical applications and the inability to redeploy applications due to performance problems. This paper examines ways to ensure critical applications are redeployed on schedule and run efficiently in Year 2000. It discusses strategies designed to assist IS organizations in managing application performance before, during and after Y2K reengineering efforts.

Taming the MQSeries Beast

Gary Powell
Boole & Babbage

MQSeries from IBM has been gaining momentum in the marketplace in the last few years as the preferred messaging middleware product, particularly for large environments with many distributed, homogeneous platforms. However, enterprises with high volumes of message traffic are realising that the management tools provided by IBM to monitor message traffic are insufficient for effective management. The requirement for extensive monitoring, centralised configuration updates, and in particular automation of responses to problems are essential to ease the MQSeries management burden. This paper focuses on MQSeries management requirements. It discusses options for implementation that would ease the subsequent management burden, clarifies some of the myths surrounding MQSeries, discusses generic requirements for management effectiveness, and highlights the need for automation to reduce staff involvement in complex management issues.

Crypto S/390 101

Phil Smith
IBM Australia

Security traditionally was Userids/Passwords, with a select few working with line encryption, these processes still work and work well, but the delivery of service has fundamentally changed who the customer is and how they connect, so what has changed on S/390, where can it be used and why.
