To transfer data with an RPC, you call the rpcCall method specifying the SPP service group name, service name, input parameters, input parameters length, service response storage area, and response length. The maximum response length that can be specified with the rpcCall method is 1 MB. You can change this value using the dccltrpcmaxmsgsize operand of the TP1/Client/J environment definition.

The following figure shows data transfer with an RPC.
