Standby Concept for FOXMAN-UN
The FOXMAN-UN standby concept provides different possibilities. Standard options:
• Cold standby: a standby machine is used to take over the management from the working (main) machine in case of an error. While in cold standby, the standby server regularly fetches the database from the main server to keep its database synchronized.
• Warm standby: The main FOXMAN-UN server and the standby server machines are connected to the network, and backing up their database in regular intervals. In case of a failure of the main server, the warm standby server takes over automatically. While in warm standby, the standby server regularly fetches the database from the main server to keep its database synchronized.
Please note:
The term machine represents either a workstation or a server.
The criteria of all recovery methods are based on the importance of speed of return to normal operation.
