Choice and Setting of Alternative Server

Choice of Alternative Server

Choose a server that fulfills the following conditions as an alternative server and configure the settings for HULFT-HUB Server. For details on the settings of an alternative server, refer to Management Information for Alternative Server.

  • The password for 'administrator' is the same between the active server and the alternative server.
  • The server is not the alternative server of another server (if the server is already registered as an alternative server, you cannot use the server as a new alternative server).
  • The version, the level, and the revision are the same between the active server and the alternative server.
  • The alternative server is not a server outside of control.
[Note] If the server that you choose as an alternative server contains existing management information, the management information is cleared when the server is specified as an alternative server.

 

The following explanation assumes that the active server is HUBSVR1 (the server at Tokyo headquarters) and the alternative server is HUBSVRB (the alternative server at headquarters).

Addition of Alternative Server to Structure Diagram

  1. Start HULFT-HUB Manager and log in to HUBSVR1 (the server at Tokyo headquarters) as 'administrator.'

    For details on the procedure for adding a server, refer to Addition of Servers.
