EZBH021E

Explanation
 Check CSRES_AUTOQ_RESOLVEVIA detected that the
RESOLVEVIA statement is specified with the value TCP in the global
TCPIP.DATA file when the autonomic quiescing of unresponsive name
servers function is active. This function is enabled by specifying
the AUTOQUIESCE operand on the UNRESPONSIVETHRESHOLD resolver setup
statement.
 The default value for the RESOLVEVIA statement is
UDP. If the autonomic quiescing of unresponsive name server function
is active, the resolver polls unresponsive name servers by using UDP,
not TCP. If your installation uses TCP to forward the DNS queries
generated by an application to name servers, the results of  the resolver
polling attempts by using UDP will not accurately reflect the responsiveness
of the name server in your installation.

System action
 The system continues processing.

Operator response
 If you want to continue using the autonomic
quiescing function with RESOLVEVIA  TCP, no action is needed.
 If
you no longer want to use the autonomic quiescing function, or the
RESOLVEVIA value should be UDP, contact the system programmer.

System programmer response
 If you want to use the autonomic
quiescing function with RESOLVEVIA TCP, no action is needed.
 If
you want to use the autonomic quiescing function with RESOLVEVIA UDP,
remove the RESOLVEVIA statement or change the value to UDP in the
global TCPIP.DATA file. After the global TCPIP.DATA file is corrected,
instruct the operator to issue a MODIFY RESOLVER,REFRESH command to
update the value.
 If you no longer want to use the autonomic
quiescing function, remove the AUTOQUIESCE operand from the UNRESPONSIVETHRESHOLD
resolver setup statement in the resolver setup file. After the resolver
setup file has been corrected,  instruct the operator to issue a MODIFY
RESOLVER,REFRESH,SETUP=setup_file_name command
to stop the autonomic quiescing function.
