OpenTP1 Version 7 Description

7.3 TCP/IP resources that OpenTP1 uses

If you create a large-scale system using RPCs (the dc_rpc_call function, the dc_rpc_call_to function, and the XATMI interface that uses TCP/IP) of OpenTP1, the number of TCP/IP ports may run short or a communication error may occur.

This section describes how to restrict the number of ports that OpenTP1 uses and how to tune the network environment.
