I thought I posted this code sample but I guess I forgot to do it. 
If you have done the runmqsc command for Channel Status for all channels of a queue manager as follows:
1 | DIS CHS(*) ALL |
And you wanted to do the same thing via a program, here is a fully functioning Java MQ example that will connect to a remote queue manager, issue a PCF “Inquire Channel Status” command, get the PCF response messages, loop through the PCF responses and output the information. You can download the source code from here.
For more information about the PCF “Inquire Channel Status” command, go to MQ KnowLedge Center here.
