abstract = {We upgraded the Injection Archiver System of the SuperKEKB collider. It records the information related with the beam injection. The system is configured on the EPICS network. The database server employs Archiver Appliance as the database management system. In addition, the distributed shared memory is installed on the database server. Its memory area is synchronized with other nodes such as bunch current monitor via the optical connection. Therefore the database server can collect the data like bunch current at the RF-bucket which the beam pulse is injected. By using this dedicated optical network, we succeed the high-speed and stable data acquisition. The injection data can be recorded, pulse-by-pulse, in 50 Hz without any packet loss.},
