APING is the APPC equivalent of the TCP/IP PING command and provides a way of testing SNA connections.
APING exchanges data packets with a partner computer over APPC and measures the time taken for data transfer. APING can be used to get a first estimate of the session setup time between two computers, and the throughput and turnaround time on that SNA session.
You can use APING to determine whether a session can be set up between two computers and to display extensive error information if session allocation fails. APING consists of two transaction programs: APING: which runs on the client, and APINGD which runs on the server.
Refer to your SNA communications product documentation for information on the APING utility.
