Use the OMVS rndc command to manage the DNS daemon
The rndc utility can be used to provide a variety of functions that can be helpful in debugging
name server problems. For example, the name server’s cache can be viewed using the
dumpdb parameter, and debug trace can be turned on or off using the trace parameter. If you

flush
parameter.
