Abstract :
The operation Logging System has been designed and built using the Oracle database for the twenty-two synchrotron radiation beam lines at the 2.5 GeV positron storage ring at the Photon Factory, where X-ray/VUV synchrotron radiation experiments are simultaneously carried out. The operation Logging System has a real-time capability to automatically store the database with all possible operational events of all vacuum valves/shutters and interlock signals, and all static operational data, including the pressures of the beam lines and the storage ring, and related operational data which represent the physical behaviors of the beam lines. By retrieving any combination of operational data, the system allows one to reproduce the physical behaviors that have occurred in the beam lines
