using a single Session.

Hello @Akechi Sato

A single RFA Session can connect to multiple connections. You can specify
multiple connections in connectionList configuration of Session. Each connection is separated by a comma as an
example shown below:

consSession
connects to 2 connections, conConnection1 and conConnection2.

Each
connection specifies serverList and portNumber to each server IP/host name as
the following examples:

conConnection1
connects to ads1 at port 14002 while conConnection2 connects to ads2 at port
14002. ads1 and ads2 provides a different service.

To
subscribe a RIC to a proper service, please specify the service’s name to the
service providing data of the RIC in a request message. For
example: if a RIC named TRI.N is provided by a service named Service1,
the source code to set the service’s name and the RIC should be:

…
// ommmsg is an instance of com.reuters.rfa.omm.OMMMsg class 
// set to request RIC named TRI.N to the service named Service1
ommmsg.setAttribInfo("Service1", "TRI.N", RDMInstrument.NameType.RIC);
// Set the message into interest spec
ommItemIntSpec.setMsg(ommmsg);
//subscribe the RIC to the specified service
Handle itemHandle = _mainApp.getOMMConsumer().registerClient(_mainApp.getEventQueue(),ommItemIntSpec, this, null);
