Sorry I omitted some details from my previous message. I have already all the solution in place working through a standard OSA adapter. The solution is based basically on two components: the pr3287 program and another program that receives the data stream from a pipe connected to the output of the pr3287. The connection with the OS/390 is through multiple LUs (one LU for each pr3287 process). Now in order to increase the bandwith I would like activate an OSA Express or CTC connection. The one with the lower impact on the CPUs for this situation.
