TP1/Client/J enables you to send and receive messages while a connection is established between a CUP (Java applet, application, or servlet using TP1/Client/J) and a RAP-processing server. Such a connection is called a permanent connection. When you execute RPCs that use the remote API facility, chained RPCs, or the transaction facility, you much ensure that a permanent connection has been established.

By establishing a permanent connection, you minimize the number of control packets for establishing and releasing connection, thereby improving communications efficiency.
