Bio

Since more than 30 years the primary responsibility of A. Goetschy is to ensure full availability, optimum performance and integrity of the DBMS's (IMS and DB2) and the data within his company (UBS AG, formerly Swiss Bank Corporation).
He is in charge of the development of tools (such as DBICF, DB2ICF...) which enable  to keep our DBMS's and our data reliable and available and  allow to other groups (operations and applications) to more easily perform their daily backup-, recovery-, maintenance-, housekeeping-, prototyping-, and performance-tasks. André Goetschy is a regular and successful speaker at the IBM IMS/DB2 Technical Conferences in Europe as well as a frequent speaker at IDUG Europe and has won the award of 'Best European User Speaker' in Berlin 1995 with the presentation 'How to relieve Batch-Window-Constraints' which has also been held by him at IDUG/Dallas in 1996.
