Thread: Redundant WEB Server

    Default Redundant WEB Server

    Hi,
    We have configuration with 2 WEB servers (main and standby).
    But WEB client not connect to standby WEB server when main WEB server (ZenWebSrv service) was stopped.
    Content of the file global_vars.js on WEB client is:
    // Here enter the exact string how your project is named
    var PROJECTNAME = "UG";

    // Please enter here the computername, where your zenOn Runtime is installed and running
    var RUNTIMESERVER= "SOIKVS-1";

    // Here you have to enter computername, where you installed the zenon WEB Server
    var WEBSERVER = "SOIKVCOM-1,SOIKVCOM-2";

    // Enter an optional init-zenOn-function to be executed when the webclients connects to its server. Defaultvalue = "Init"
    var INITFUNCTION = "Init";

    // Enable zoom feature (will stretch the project resolution to the size of the webclient control) OFF = "0" / ON = "1"
    var ZOOM = "0";

    // Here you have to enter the version number corresponding to the WEB Client.
    var VERSION = "6,22,0,0";

    Best regards,
    Alexander

    I'm not sure if the definition of the WebServer (var WEBSERVER = "SOIKVCOM-1,SOIKVCOM-2";) needs the char ".
    Try it without "
    var WEBSERVER=SOIKVCOM-1,SOIKVCOM-2;



    Take care that there is no blanks in between.

    Regards,

    hello,

    i think that the char " is needed in that case. how do you realize that the redundant web server isn't taking over (be carefull, the "swap process" is taking some time) ? how does your configuration look like (own pc for zenon rt, own pc for web server, ....)?

    regards,
    jürgen
