DISPLAY NODE
The DISPLAY NODE command reports the status of the TCP/IP connections for a zDMF server. A message is repeated for each connected zDMF server.
Note: The DISPLAY NODE command
is not available in batch mode.
For information on the startup parameters, see Configuring the zDMF server parameters. Command field descriptions for the DISPLAY NODE command are included in Table 1 .
