12.88 to 6.91 - BACS - Electronic Funds Transfer - Performance Modelling Consultant

Edgware, Middlesex
My duties involved modelling the ICL Series 39 configuration requirements (CPUs, Disks, Cartridge Tape, Open Reel Tape and Memory) for and predicting the response times and batch elapsed times of online, batch, dump and recovery processes of a major replacement electronic funds transfer system using an IDMS database.

The duties involved the identification of significantly long running processes through benchmarking and liaison with the development design staff to provide COBOL source code and modelling input so as to predict of the CPU overheads and the conventional and physical I/Os involved in selected processes. Modelling used a mixture of VCSR, analytical and spreadsheet based techniques. The work involved use of the ICL Data Dictionary, holding variants of BIS metadata, to provide additional methodological data for modelling. The duties also involved project planning using PMW,

Other exercises included the 'baseline' modelling of VCSR's predictive capabilities, evaluation of alternative modelling products (Athene, Capacity Q, SCERT) for modelling ICL and Tandem systems.

I was also required to negotiate, establish and implement SLAs for the development configurations - defining a system for the translation of information on mainframe component utilisation into a form where it could be used as a basis for chargeout and analysing workload data so that it might be used as a basis for budgeting future computer charges.

12.89 to 8.90 VHI - Medical Insurance - Data Warehousing Consultant

Abbey Street, Dublin
An assignment, involving an IEF based BAA data analysis review and the design of an Oracle database, running on VAX equipment to support a data warehousing MIS system, for the Irish health insurance company, VHI. With IEF running on a PC, the study required advising on what data would be warehoused, the performance implication for loading and maintenance, the meta data that should be stored within the IEF system. It also required training staff in its practical use and recommending what additional ORACLE based tools would be needed to overcome IEF shortcomings.

The work also involved performance prediction of the response times and batch elapsed times of online, batch, dump and recovery processes of MIS warehouse enquiries using alternative Oracles design strategies. The duties involved project planning, acquisition of modelling input, prediction of the conventional and physical I/Os and the identification of critical SQL queries. It involved spreadsheet based modelling techniques. The work involved use of IEF and the Oracle Meta-Data Dictionary to provide the methodological data for modelling.

The design involved surveying all planned applications and existing conventional files for potential data warehousing requirements and their data sources, constructing a corporate data model to resolve inconsistencies, mapping the data model for the warehouse to an 'efficient' set of Oracle tables, determining 'indexes', devising initial load and data maintenance strategies, predicting the principal elapsed run times for loads, updates and typical SQL enquiries, determining mass storage storage occupancy and constructing a plan for the database implementation. The exercise involved supervision of two additional consultants and teaching the VHI database administration staff how they might independently undertake a subsequent exercise.

6.88 to 10.88 - SPS Education - Lecturer and Technical Author

In view of a knowledge of performance issues and database issues, a commission to prepare a number of courses. These included a 3 day DB2 Internals course which covered the DB2 elements, the various SYS structures and their contents and purposes, relationships to VSAM, data and index page contents and structures, row and data type formats, row insertion and overflow procedures, index maintenance procedures, DDL and DCL, static and dynamic SQL, privileges, threads, binds and access path selection and the optimizer.

A second course involved a practical PC based training programme for performance modelling analysts in statstics techniques used in the monitoring, forecasting and presentation of data on computer performance.

4.87 to 5.88 - Morgan Grenfell - Merchant Banking - Perf Mgt & Capacity Planning Manager

Tabernacle St, London EC2
I assumed responsibility for the development of a section consisting of five people to carry out formal performance monitoring and capacity planning across ICL, Tandem, IBM and Stratus hardware. This also involved the development of service level agreements, software, standards and procedures. Specific duties undertaken or supervised during this period were:.

  • the evaluation and selection of various analytical modelling packages
  • the introduction and use of Capacity Q for modelling Tandem, IBM 4300 and Stratus machines
  • procurement negotiations concerning suitable component upgrades with suppliers
  • the specification of ITTs containing procurement requirements for suppliers.
  • the initiation of management oriented, regular machine performance monitoring reports
  • periodic capacity planning for systems reaching bottlenecks

These duties were undertaken across Tandem, IBM 4300 running VM, Stratus, ICL Series 39 and IBM 3090 running MVS.

The duties required the creation of a common, central IBM PC-based network of micros communicating with the bank's minis and mainframes. The system exploited the 'relational database' type capabilities of dBase III+ running on a network of PCs. This automatically interfaced with mainframe software (via Automator Mi) and built a performance database which was used to produce monthly graphical reports (via Logistix and Freelance) on mainframe performance.

11.84 to 2.87 - CCTA - Government Computer Agency - Internal Consultant

Riverwalk House, London
I returned to England to act as an internal consultant for government departments (notably the Department of Transport, Department of the Environment and Ministry of Defence). Projects were undertaken on IT strategy, system performance, database design, hardware/software selection and hardware procurement. These studies involved the preparation and collection of data for inclusion in Feasibility Studies, Full Study Reports and Operational Requirements. These assignments involved substantial and constant involvement with both the SSADM and PROMPT/PRINCE methodologies. I was normally vetted for the purpose of these assignments.

Specific projects are outlined below.

  • A review of progress in the establishment of an IT strategy for the ICL systems at the Personnel Centre at RAF Innsworth. This involved the formation of a 'command' team (to control teams of some 50 staff), the supporting infrastructure for the collection and analysis of data, the establishment and justification of an appropriate strategy in the light of architectural and resource constraints and the formal presentation of the strategy to senior RAF personnel.
  • An IT strategy and quality assurance review on the organisational, configuration, hardware/software, progress, planning and resource issues of a system for the support of the Vehicle Inspectorate, Bristol. This was conducted with a staff of some 6 to 12 people in the light of the completion a DTp wide strategy to cover Driver, Vehicle and Operator systems.
  • The leadership of a team of DVLC system development personnel in the analysis and design of a DL/1 database for the support of an operational Vehicle Inspectorate database. The 2 gbyte DL/1 database was designed to support the annual testing and inspection of all heavy goods vehicles and public service vehicles by the Vehicle Inspectorate in Bristol. A major design criteria was to preserve upwards compatibility with relational database software (potentially Model 204 or DB2) and a comparision of the relative performance of the DL/1 and a DB2 design was undertaken. The JSD/JSP methodology underpinned this particular approach
  • A performance management study for DVLC involving analysis of the existing performance and workloads of a major CICS/DL1 application and the preparation of recommendations concerning the adequacy of the database design and the need for upgrade to an IBM 3080.
  • Two similar performance studies using capacity planning tools for ICL government installations (DNS and HMSO) of applications. They involved SCERT modelling software and resulted in recommendations for improvements as a means of forestalling machine upgrades. The HMSO performance review resulted in the preparation of recommendations for improving the reorganisability and recoverability of the IDMS supply system database.
  • Procurement evaluation and selection studies of relational database software for the Ministry of Defence. Software evaluated covered Oracle, DL/1, DB2, Ingres and Rapport.
  • A study into the nature, feasibility and requirements for a data warehousing facility to hold centralised register and database details concerning defence contractors using a common contractor coding scheme.
  • During this period, in view of a continual involvement with SSADM and its lack of automated support, a comprehensive set of micro based data dictionary tools using Dbase III+ was evolved, designed and implemented. These various 'tools' were brought together at DVLC to actively support the database design process during the design of the Vehicle Inspectorate database.
