I have multiple Web-AP server on live environment for fault Tolerance.
So I want to publish contents to multiple servers at publishing time.
I set up Topology Manage as following(I have two Web-AP servers "Server A" and Server B).
ID :ServerAEnvironment Discovery URL: http://ServerA/discovery Purpose :Live ID :ServerBEnvironment Discovery URL: http://ServerB/discovery Purpose :Live
ID :ServerAENWebsite CDEnvironmentID:ServerAEnvironment ID :ServerBENWebsite CDEnvironmentID:ServerBEnvironment
ID :ServerAENMapping WebappliationID:ServerAENWebsite_RootWebApp Publication URI:tcm:0-1-1 ID :ServerBENMapping WebappliationID:ServerBENWebsite_RootWebApp Publication URI:tcm:0-1-1 (ServerAENWebsite_RootWebApp and ServerBENWebsite_RootWebApp are created automatically)
But error occures at creating TTMMapping.
The error message says that "combination of CMEnvironment and Purpose and PubicationURI have to be unique".
Also it's impossible to map multiple TTMWebApplication to one TTMMapping
(Like Mapping both ServerAENWebsite_RootWebApp and ServerBENWebsite_RootWebApp to "ENMapping")
It's common scenario that Live environment have multiple servers and publishing contents to those servers.
How to achieve it by Topology Manager?
