The ATLAS detector control system (DCS) archives detector conditions data in a dedicated Oracle database using a proprietary schema (PVSS Oracle archive) and representing one of the main users of the ATLAS online database service. The contribution will give an overview about the database usage and operation experience, e.g. with respect to data volume, insert rates, and pending issues....

For the past few years, Panda Workload Management System has been the mainstay of computing power for ATLAS experiment at the LHC. Since the start of data taking, Panda usage gradually ramped up to 840,000 jobs processed daily in the Fall of 2010, and remains at consistently high levels ever since. Given the upward trend in workload and associated monitoring data volume, the Panda team is...

The Distributed Data Management System DQ2 is responsible for the global management of petabytes of ATLAS physics data. DQ2 has a critical dependency on Relational Database Management Systems (RDBMS), like Oracle, as RDBMS are well-suited to enforce data integrity in online transaction processing application. Despite these advantages, concerns have been raised recently on the scalability of...
