Web Adaptor with multiple arcgis server

Haider_Ali — Tue, 14 Jun 2016 18:21:12 GMT

According to my understating i can configure two arcgis server with one web adaptor e.g my web adpator name is arcgislb

and two gis server are gisserver1.ad.net and gisserver2.ad.net. But the problem is if i add one other is replaced i.e. if i add gisserver2.ad.net after adding gisserver1.ad.net then gisserver1.ad.net is replaced by the seciond server.

Although I have the opposite, multiple web adaptors (one http one https) on one server, I think wha tyou are trying to do is explained Multiple-machine deployment with ArcGIS Web Adaptor—Installation Guides (10.4.1) | ArcGIS for Server

My gut feeling is you only install the web adaptor (with the same name) once, and because the multiple servers are in a cluster, that takes can of it...ie, all using the same web adaptor.

What i am trying to do is similar to the first diagram of the page Multiple-machine deployment with ArcGIS Web Adaptor—Installation Guides (10.4.1) | ArcGIS for Server , but when i add a second server to the web adadptor it replaces the previous one.

I think http://image.slidesharecdn.com/administeringargisforserver-150608034656-lva1-app6891/95/administering-argis-for-server-45-638.jpg?cb=1433735539 and http://image.slidesharecdn.com/administeringargisforserver-150608034656-lva1-app6891/95/administering-argis-for-server-4… explains what i am trying to do i.e. i have to join an existing site instead of creating a new one. So that was a misunderstanding it is more like a Multiple-machine sites load balancing instead of Multiple-machine load balancing

Is there a way i can control the load balancing i.e. give the weights to the server ?

It sounds like you should take advantage of your own load balancer, like HAProxy, Apache, or NGinx, instead of use the web adaptor. You can define your own traffic rules, (like sending a request to a specific backend server based on a certain context), and assign your own weights to servers.
