[GIS] Federating multiple ArcGIS servers with Portal for ArcGIS

arcgis-portalarcgis-server

has anyone experience with a federation of two or more ArcGIS Servers with Portal for ArcGIS?

If we try federate the second AGS, we have a problem with publishing map services in the form of web-map application (we can not find this services in Portal for ArcGIS).

I suppose that I'm doing something wrong.

Is there more detailed documentation how to federate next ArcGIS Server?

Best bet is to follow the documentation on federating an ArcGIS Server site (which can be comprised of multiple GIS Server nodes), as these provide more detail.

Here is the high level workflow. Below screenshot is from Portal for ArcGIS Administrator settings, and the Portal has already been federated against one ArcGIS Site.

To add another site:

Hit Servers tab
Add an ArcGIS Server Site. Point to the REST services URL, the Admin URL, and provide a username and password of the primary site administrator (default username is siteadmin).
Choose which ArcGIS Server Site will be the hosting server.

You should now see the services from the second ArcGIS Server Site appear as new items in your Portal.

Typically you have one server setup as a hosting server - this requires you to also make use of the ArcGIS Data Store. This opens up a lot of benefits (e,g, analysis services) to your WebGIS. But you may want to federate more stand-alone ArcGIS Sites. The following graphic shows two federated servers, one setup to be a hosting server, one just federated. Both publishing workflows automatically create a corresponding item in the portal. Delete the item, the service also gets deleted.

I think I've found the solution to this issue. The code works fine* if security is disabled in chrome (Chrome.exe --disable-web-security), which means my code is ok. The error seems to say that the server will not accept the header X-Requested-With which is added by default by dojo xhrPost. Therefore I set the header value to null (as suggested by ESRI support) and the request went through fine in Chrome/FF

I have submitted a request to ESRI to get the header added to the server as suggested by this exchange

Edit: it works in IE9 using dojo.xhrPost so long as the site and ArcGIS online server are running on the same protocol, most likely https.

*Looking at the way "configure application" works in fiddler on ArcGIS online site they do not use 'update item' but instead 'add item' with overwrite = true. In order to get the webmap template and its associated data use the code getTemplate code listed below.

        addItem: function (item, itemData) {
            var cont = item;
            if (!cont) cont = {};
            cont.f = "json";
            cont.token = this.token;
            cont.text = dojo.toJson(itemData);
            cont.overwrite = true;
            cont.item = cont.id;
            cont.itemType = "text";
            var xhrArgs = {
                url: 'https://xxx.maps.arcgis.com/sharing/content/users/xxx_wilton_d/addItem',
                token: this.token,
                content: cont,
                handleAs: "text",
                headers: {
                    "X-Requested-With": null
                },
                load: function (data) {
                    data = dojo.fromJson(data);
                    if (data.success == true) {
                        console.log('Updated item data!');
                    } else { console.error('Failed to update item data!'); }
                },
                error: function (error) {
                    console.error(error);
                }
            };
            dojo.xhrPost(xhrArgs);
        },

         getTemplate: function () {
            //gets the application which has been created from our template and it's configuration data
            var urlObject = esri.urlToObject(document.location.href);
            if (configOptions.appid || (urlObject.query && urlObject.query.appid)) {
                var appId = configOptions.appid || urlObject.query.appid;
                var d1 = this.getItem("rest/content/items/" + appId, null);
                var d2 = this.getItem("rest/content/items/" + appId + "/data", null);
                var dList = new dojo.DeferredList([d1, d2]);
                dList.then(dojo.hitch(this, function (response) {
                    //update the item data
                    var item = (response[0][1]);
                    var itemData = response[1][1];
                    //assume a small change has been made to the item or its data. Save it back to the server
                    this.addItem(item, itemData);
                }));
            }
        },
