Standby System
Backup of the database only protects the data used for the management of the network. However, this does not provide any failsafe or graceful rollover mechanism in case of a failure of the hardware on which the application is operating.
By failsafe, it means that there is no possibility that an error can occur. The typical hardware configuration being used for FOXMAN-UN to manage the network could be:
• a single workstation to manage the whole network (user interfaces, agents and database installed on the same machine);
• a server with the central database.
In each of the above cases it is absolutely paramount to be able to recover the data and bring the manager back into operation in the shortest possible time, with a graceful switch over to another workstation or server.
