dear Readers, Question: For A REST service on A particular server belonging to 2 or more Load balanced (LB) servers, how to check its availability using IP or server name from a web page on another webserver in the same domain? We have a load balanced arc gis servers with a common human readable server name for the two (or more) servers housing REST services to be consumed by our Silverlight and JavaScript applications.  By design of LB servers, assign requests in a round robin fashion.  if at that time, the assigned server's REST service is down, then the application throws an error. We had created an application that queries the human readable front server name/service/ to query it - this app might fail to report that the service is down if the request is assigned to the working server and the admins will not know about it and the end user might report it.  we want to query individual server IP/services and know about it before the end users. LBServerName ---> 192.168.121.111 and 192.168.121.222; if my polling app hits .111 server and reports a success for a particular service, and if the web application of the end user assigns the request to .222 server and if the particular service is down, then the end user reports the error and the admins will not know it in advance. version AGS 10.3.1 on windows 2008 r2. any suggestions would be useful regards ravi. ...

dear Readers, thank you for taking the time to read this post and contemplating potential solutions for the same: Situation. We have a web app builder 1.1 - the application consumes a map on a portal 10.1.  We made changes in the past and used download button to get the latest code and publish to the servers.  It was working fine. Recently, we made modifications to the portal server that contained the main map that resulted in modifying the itemId value in config.json - http://myServerName.Domain.com/arcgis/home/webmap/viewer.html?layers=0a7d2f5a8cfe4babbe113ec5c9cd5462 - this value. To start with, we had changed the itemId value of config.json file in the web app builder environment  to use the same underlying map from the portal - but with the new ItemId. Now problems encountered are as follows: 1. when we download from a working WAB for deploy - downloaded code  remembers the old itemId and not the new one even though the code folder under the WAB folder structure has the new itemId in config.json.  So we had to manually change the itemId everytime before copying the contents from the download zip/unzip folder to the server location. 2. Any new widgets that were create after the 'itemId' change are not showing in the published app  on the server but not on the WAB launch menu. 2b. On the server version, we see WIDGET TEMPLATE where we had mad changes.  On doing a file search on the download 4 deploy zip/unzip folder, we could see the html / javascript changes that are working on WAB launch menu.  The code on the server contains the new html controls and javascript code - but they would not show up. any input to resolve our current situation would be great. regards ravi ...

dear Readers, good morning. thank you for taking the time to read this article. we have a working SL app in production. the app development started with ESRI API 1.0 and was upgraded to the latest API as needed.   The end users were interested in the toolbar that had arcmap look and feel that was deprecated after v2.x.  For such user community, ESRI was kind enough to create a dll ESRI.ArcGIS.Client.Toolkit.DataSources.dll (v2.4 - 2.3.0.2440) based of toolkit source 2.4 from Codeplex (or a similar code repository). The app is working great till we are trying to do the following: 1. add a wms layer from a different domain (over the internet) that requires unique userid and password due to the sensitivity of imagery.  the imagery available from the outside source is available for the entire nation. we have not heard from the provider about using a common app based user id /password like we use for the app to communicate with the database.  they are examining the request and have not responded. 2. while trying to use the sample page's wms example, UI (esri.ArcGIS.client dll version = 10.2.1.0 (v 3.2) Toolkit.Datasources dll version = 2.3.0.2440 (v2.4) As the application steps into the following function - from the place where the following is called: private void AddWMSTest() { WmsLayer wmslayerTest = new WmsLayer(); wmslayerTest.Url = "https://Outside.ServiceProvider.com/mapservce/wmaccess"; MyMap.Layers.Add(wmslayerTest); } ...

dear Readers, we have a SL app in production that consumes ArcGIS image services (cached tiles) from the ArcGIS server 10.11. on top of the imagery we have a mapserver service with labels from an MXD (feature layer). ISSUE: when the layer is seen without imagery, the SL app displays the labels as black color fonts on white background. When the colorful imagery is turned on for display, the labels loose their black color and display in various shades of white, gray, and black. When we go to the same area in ArcMap by adding these 2 layers from ArcGIS server to the table of content and examine the same area (approx. scale 1: 36000 to 1:9000), the labels do not exhibit the above described behavior and stay black with or without the imagery turned on. do we need to modify the configuration of the services - I do not recollect writing any code for display features. thanks and regards ravi. ...
