In the year 2004 I switched to the "Optimization & Tuning"-department and since then I have had multiple trainings for optimizing Mainframe-programs. I was able to build up a vast knowledge on different optimization-areas - with the main emphasis on tuning hierarchical Databases (DB2 for zOS).Since then I have accompanied many releases, projects and task forces in order to optimize program-runtimes and reduce CPU-consumption and hence reduce cost.My experience was frequently needed in Major incidents and "Warrooms".

- Phases and Major-Projects within this period: - 1996: extensive training program on the Mainframe (zOS) - 1997: civilian service - 1998: Development and implementation of the new business-application 'VALUTEN-NEU' (z/OS, IMS DC, IMS DB) - 1998/1999: BzE (Merger-Project: Bank Austria and Creditanstalt, part 1) - 1999/2000: Y2K - 2000/2001: heureka! (Merger-Project: Bank Austria and Creditanstalt, part 2) - 2001/2002: €uro-implementation - 2003/2004: Development and Implementation of GEOS-Nettodaten (Securities-System)- Application Responsibility for several Bank Austria-applications (VALUTEN-NEU, BASTA, ZENTRUM, ISIS3)
