Abstract

The ATLAS trigger configuration system uses a centrally provided relational database to store the configurations for all levels of the ATLAS trigger system. The configuration used at any point during data taking is maintained in this database. A interface to this database is provided by the TriggerTool, a Java-based graphical user interface. The TriggerTool has been designed to work as both a convenient browser and editor of configurations in the database for both general users and experts. The updates to the trigger system necessitated by the upgrades and changes in both hardware and software during the first long shut down of the LHC will be explored.
