![]() This proliferation of measurements beyond the initial scope showed the correct design of the system, as well as the performance limitations within the actual hardware configuration. Hence, for the 1995 startup, the size of the measurement system was increased drastically to fulfill a variety of measurement needs. Many new features of Oracle7 were exploited to reduce the surrounding software.During the 1994 SPS physics run, this new measurement system was commissioned successfully and the infrastructure proved to be acceptably reliable. A great attention was paid to proper storage allocation for tables and indices since this has a major impact on the efficiency of the database, due to its time-critical nature. The kernel of this new measurement system is an on-line ORACLE database.The NIAM method was used for the database design as well as a technique to tag synchronized data with timeslots instead of timestamps. For the 1994 SPS startup, a completely new and redesigned measurement system based on client and server C-programs running on UNIX-workstations was introduced. Beam parameters such as intensities, positions and losses need to be rapidly available in the SPS control room to allow the operators to monitor, judge and act on beam physics conditions. In order to maintain efficient control over the hadron and lepton beams in CERNĀ¹s SPS accelerator, measurements are of vital importance.
