Implemented and documented backup and recovery processes for corporate LAN servers using IBM ADSM

Project Management

Implemented Magstar tape solution for mainframe and AIX platforms which consisted of research; negotiation; recommendation to senior management; acquisition of assets; planning for installation; scheduling of resources; activation in production environments

Participated as Technical Project Leader of corporate Y2K readiness team

Coordinated several CPU upgrades including; negotiation of terms with hardware/software vendors; workload modeling; installation into production environment

Solutions Development

Designed and coded Netview automation routines using REXX and IBM Infoman to track problems and respond to console messages

Implemented IBM Solution Evaluation Tool and developed scripts to unit test, system test and stress test internally developed client/server applications

Negotiated Service Level Agreements with I/T and End User departments; presented results to senior management; designed and implemented reporting mechanisms

Performance Tuning / Capacity Planning

Organized an MVS/ESA exploitation effort by writing custom software to examine system statistics and use data-in-memory concepts to decrease over-night run times

Led a team that examined all components of a three-tiered multi-vendor client/server application that was suffering response time problems; improved response time to acceptable levels and allowed implementation to proceed

Participated in multiple continuous improvement teams to monitor and improve CICS transaction response time

Implemented DB2/Connect to allow SNA access to mainframe databases

Worked with development team and IBM to establish ODBC use of mainframe databases using COGNOS

Security Administration

Implemented Global Access Checking in RACF to reduce I/O contention and improve system throughput

Utilized RACF to provide internal DB2 security

Interfaced with internal auditors to define security policies and resource ownership

Examined SMF data on-demand to identify security violations

Converted TSO from UADS to RACF security

Trained Helpdesk and support groups in RACF
