Abstract
The Data processing department at the DEPT manages a centralized maintenance application for the nineteen power plants in France. This application performs fourteen million CICS transactions every month, passing through the Electricite de France national teleprocessing network. Operation is split among two IBM 9021 computer partitions located one hundred kilometres apart for backup and security reasons in the two computer centres of the STI (EDF Data Processing Department) and the R and DD (EDF Research and Development Department). The CICS are stopped each night at 10.30 so that the data bases can be backed up onto cassettes and so that the work from the plants can be processed in batches. The plants update the number of bases and extract subsets intended for the plants. From the outset, considerable resources were assigned to this operation: cassette insertion robots, a high-power batch processing scheduling and planning tool optimizing parallel step work, high-power computers: two IBM 3090-40J computers were dedicated to this application as early as 1989. However, the buildup and evolution of this application led to ever greater basic volumes and increasingly voluminous and complex batch processing, leading to reduced transactional availability by pushing back the startup times. To combat this trend,

In particular, on the partition operated by the computer Centre in the Applied Mathematics and Data Processing Service of the Research and Development Department at EDF, a number of studies were conducted, as described in the following text. This description comprises three parts: - report on the studies and steps taken, both from the hardware and the software viewpoint; - an evaluation of their effectiveness and the results obtained; - the new areas for study selected.}
