I have setup Always on with four server


Server Role AvilabilityMode Failover Mode ReadabilityMode

Server1 - Primary Syncranized Automatic Failover Yes
Server2 - Secondary Server Syncranized Automatic Failover ReadOnly Intent
Server2 - Secondary Server Syncranized Manual ReadOnly Intent
Server2 - Secondary Server Asynchranized Manual No


I have given two connection string in application one for Readwirte and other for Readonly access and the same is validating

connectionString="Data Source=192.168.1.1\SQL;Initial
Catalog=DBNAME;User
ID=XXXX;Password=XXXX;" providerName="System.Data.SqlClient"


connectionString="Data Source=192.168.1.1\SQL;Initial
Catalog=DBNAME;User
ID=XXXX;Password=XXXX;" providerName="System.Data.SqlClient"
Aplication Inetent=Readonly


Here i have two doubts.

1. Using second connection string which server wil be active for read only ( server2 or server3 ? or Both)
2. If anything happend in my second server inbetween the trasaction what wil happend ?
3. If failover comes to second server is it first server will automatically will readyonly load ?



Thanks in advance
