TRACE RESOLVER statement
Use the TRACE RESOLVER statement to have a complete trace of all queries to and responses from the name server issued. Specifying TRACE RESOLVER is equivalent to the OPTIONS DEBUG statement.
Restrictions:
- The TRACE RESOLVER statement should not be specified in the GLOBALTCPIPDATA file. Before making a TCPIP.DATA file global, it should be tested for syntax errors. Trace output should appear in the SYSTCPT data set or RESOLVER_TRACE file that was specified.
- TRACE RESOLVER should be the first statement in the TCPIP.DATA statements to get the maximum trace output.
