To enable the use of the availability group listener, you need to modify the database connection setting of the Administration Service. You can specify the availability group listener in the SQL Server field on the Change Active Roles Database wizard pages provided by Active Roles Configuration Center.
Depending upon the location of the Management History database in your Active Roles environment, you need to specify the listener in the SQL Server field on the Connection to Database page, on the Connection to Management History Database page, or on both pages. The value in the SQL Server field must identify the DNS host name and, optionally, the TCP port of the listener of the availability group to which the database belongs. For example, if the DNS host name of the listener is AGListener and the TCP port used by this listener is
1234, the value is AGListener,1234. You may omit the port number in case of the default port, 1433.
