Backup Pos Server - Sharp UP-X300 Instruction Manual

■ Backup POS server

The POS server system allows you to set a terminal as the backup server by user setting. The backup
server has the same data in its databases as the ones in the POS server. When the system updates
the Master Database at the POS server by each terminal, the POS server system automatically updates
the copy of the Master Databases at the backup server immediately.
When the POS server outage occurs, the terminals can't access the Master Databases at the POS
server. Then the operations are maintained by the following instruction:
How to read/write the Master Databases at the POS server
At the terminal a selection window appears to select Retry or Use Backup Server Only. Select Use
Backup Server Only at the terminal when the outage is detected.
Then the terminal cannot access the Master Databases at the POS server. Instead, the terminal
accesses the Master Databases at the POS server without restriction in terminal operations.
