With the latest round of energy price increases, many domestic users are looking to switch suppliers. EDF gains and loses about one million customers each year, meaning the mainframe database grows by two million records.
Benoit Laclau, managing director of the business improvement and technology arm at EDF Energy, said, "Datacentre and application support teams have worked on a series of initiatives to ensure customer growth and associated data and processing demand could be contained within existing capacity." This has involved tuning batch and online applications and identifying integration inefficiencies.
These initiatives have included improving the categorisation of workloads and priorities, allowing EDF to make more efficient use of the mainframe.
Laclau said, "Working together with our colleagues in the business, we continue to highlight practices that place high demand on the system and we have adapted our output operations to accommodate later delivery of print output due to elongated batch elapsed times."
