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.

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

1. changes introduced before a "system" becomes operational
2. changes implemented after a "system" is operational
3. unplanned changes (due to equipment failure, human error, disaster)

New Methods for Measuring Function Points in Outsourcing Contracts
Pam Morris Total Metrics
Function Point Analysis (FPA) is used by organisations worldwide as one of the measures used to establish the baseline size of their software assets. This paper introduces new techniques, which enable all the functionality delivered and worked on by the supplier to be included in the productivity performance monitoring of these contracts. Typically only the business applications layer can be measured using FPA. The infrastructure software eg. Utilities, device drivers and gateway applications, are usually overlooked because FPA is not designed to, nor easily adapted to, measuring internal layers of functions not delivered to the business user. This new Full Function Point Technique developed by the University of Quebec in Montreal is a refinement of the FPA technique. It is no longer limited to only measuring MIS type applications but was specifically designed to meet the needs of organisations who build and support infrastructure applications and real-time and embedded software.

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?

The Folly of Ownership, Revisited -or- Whose CICS Region is That, Anyway?
Stephen L. (Steve) Samson Candle Corporation
A nearly universal trend in large IT installations has been to transform resources "owned" by user departments to installation ownership with more or less automated management. Examples include DASD volumes and JES initiators. However, one counterexample to this trend persists: CICS address spaces ("regions") are still overwhelmingly owned by user departments or the proxies who maintain their inventory of applications. Consequently, the set of transactions resident in each region mixes the important and the unimportant, the sprinter and the slug. Since the execution environment is managed only at the address space level (when enclaves are not defined), the effect of such transaction mixing leads to less than optimal results in both performance and performance management. This paper proposes some solutions to achieve better resource distribution, better control of transactions' performance, and increased efficiency.

Client Server in a Government Agency! Five years of Failure
Bill Stewart Consultant
We wish to know whether a project is successful; but although everyone hopes to learn by a mistake, nobody likes to admit they have made one. One sort of project is to devise a strategy; and strategists avoid admitting they have failed by arguing, wrongly, that they have no responsibility for implementation. The mistakes they make include failing to select and promote management and technical methodologies, and to establish in sufficient detail a logical connection between the methodologies and the perceived and implicit requirements of the organisation. We consider the case of client server information technology in a government agency over the past five years.

Client Server Volume Testing
Peter Taylor ATO
Over the last year the ATO has been developing new applications using the Cool-Gen (ex-COMPOSER) RAD tool. These applications still rely on the MVS environment for CICS and DB2 but have given the Business people a look and feel of a window application. The challenge has been to maintain consistent support in the area of Volume Testing for these applications.
This paper will describe the joys and experiences of converting to Mainframe Client/Server testing and what to look out for when you bite that bullet. The audience will gain a better insight into the "How-To's" of testing a Mainframe Client/Server application.

End-To-End Response Time and Beyond: Direct Measurement of Service Levels
Mike Tsykin FBA Computer Technology Services
End-To-End Response Time (ETE RT) is the preferred metric for the measurement of service Level. It shows whether a User was prevented from working at full capacity. ETE RT is an indirect metric due to difficulties in identifying a transaction in Open Systems. Other measurements may be better suited to the task. One of many is the time when a User was capable of working but was prevented from doing so.
This paper reviews existing approaches to measurement of ETE RT, lists available tools, outlines the concept of direct measurement of Service Levels and describes an approach to its implementation.

PSLC in an Hour - Constructing a Simple Parallel Sysplex
Mark Heers Amdahl
IBM have recently imposed more stringent requirements to continue to receive the benefits of IBM's more cost effective Parallel Sysplex Licence Charges (PSLC). In effect, this means that sites with multiple processors will have to implement some form of Parallel Sysplex sharing in the near future to continue receiving the benefit of PSLC. This paper explores the construction of a simple Parallel Sysplex. Whilst the paper does not recommend quick and unplanned implementations, it is designed to give an idea of the requirements of constructing a Parallel Sysplex. As in all construction, it commences with the foundations of a sysplex - the definitions of the signalling paths between the MVS images, the implementation of a common timer reference, the control of resource serialisation (under GRS) and the creation of a sysplex couple dataset. Upon these foundations, a set of guidelines and actions called policies are defined to describe the usage and resourcing of the Parallel Sysplex by various applications. Finally the paper describes the implementation of a sample application, namely the sysplex-wide recording of hardware and software failures (logrec error data).

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.

Why S/390
Phil Smith IBM Australia
The marketplace is changing, if it has not already changed. Customers now basically want to be able to connect to any application, at anytime and anywhere. This may sound like a fundamentally sound process to adopt, but it puts pressure back on the organisation supplying the service. Choice of Operating System, Data Base, security package, hardware etc all adds confusion and doubt to the decision process. So why should any one platform stand out more so that any other when running "Core Business" applications.

Tuning New Technology DASD
Tom Beretvas Beretvas Performance Consultants
With the advent of storage processors (e.g., IBM RAMAC, EMC Symmetrix, IBM RVA2 etc.) conventional wisdom of DASD tuning has to be revisited to reflect the characteristics of the new world of storage processors. This paper provides the overview of a methodology for identifying and curing DASD performance problems. The old and new DASD worlds are compared. Case studies illustrate the process. The methodology presented includes the metrics to be examined and some of the data reduction techniques. It also indicates potential avenues for solutions. The process begins by looking at RMF data and refining the scope of examination so that DASD, control unit and path performance problems can be identified.

Storage Processors Performance Comparison Parts 1 & 2
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.

Coming in from the COLD?!
Lynn Collier Storagetek
There has been a dramatic change in the way in which automated tape is being deployed in the marketplace. From a traditional backup environment there has been, and continues to be, a significant increase in the use of automated tape to facilitate the introduction of document management solutions, support of image archives and to extend the use of automation to enable new business applications to be delivered. In an area previously associated with optical disk there has been a massive swing in the definition of storage requirements. These new application areas have specific profiles and requirements relating to capacity, performance, data retention and management. The metrics and processes to plan and manage the storage centric environment are key to developing capacity planning and performance management techniques for the future.

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.

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.

THE COPY SUITE : Sorting through the Storage Tool Bag
Rick Sewell Amdahl Pacific Services Pty Ltd
Over the last few years there has been a major improvement in the availability of tools that will allow increased data availability. All of these tools provide the ability to improve data availability through a number of different techniques. However, there are a number of issues such as hardware and software dependencies so trying to understand what approach will really solve individual problems is not all that easy. Choosing the appropriate tool also hasn't been made any easier by the use of a multitude of acronyms such as PPRC, XRC, SRDF, HODM, HRC and TDMF. This paper will describe all of the various tools available for increased data availability and examine both the positive and negative aspects of each. From attending this paper the audience will gain a better insight into what tools are available and which will be appropriate to their individual needs.
