EZD2037E

Explanation
 This message is issued when the resolver function
defined by the resolver_setup_value value ends
abnormally. The operator can restart the resolver function by issuing
a MODIFY RESOLVER,REFRESH or MODIFY RESOLVER,REFRESH,SETUP= command.
 Possible
values of resolver_setup_value are: AUTOQUIESCE
UNRESPONSIVETHRESHOLD

System action
 Processing continues.  If the resolver_setup_value value is AUTOQUIESCE,
the resolver stops performing the autonomic quiescing of unresponsive
name server function, and instead performs the network operator notification
of unresponsive name server function. All  name servers previously
identified by message EZZ9311E in z/OS Communications Server: IP Messages Volume
4 (EZZ, SNM) as being unresponsive are now considered
responsive, and the resolver will now send the DNS queries that are
generated by an application to these name servers. If the resolver
determines subsequently that the name server is still unresponsive,
the  resolver will generate message EZZ9308E in z/OS Communications Server: IP Messages Volume
4 (EZZ, SNM) to notify the network operator.
 If the resolver_setup_value value is UNRESPONSIVETHRESHOLD,
the resolver stops performing all monitoring of unresponsive name
servers. All name servers previously identified by message EZZ9308E
as being unresponsive are now considered responsive. All name servers
previously identified by message EZZ9311E as being unresponsive are
now considered responsive, and the resolver will now send DNS queries
that are generated by an application to these name servers. The  resolver
will not generate any additional messages EZZ9308E or EZZ9311E.

The message remains on the operator console until one of the
following events occurs:  The operator issues a MODIFY RESOLVER,REFRESH command. The resolver
restarts the function at the previously defined level of functionality.
The operator issues a MODIFY RESOLVER,REFRESH,SETUP=resolver_setup_file command.
The resolver activates the level of function defined in the resolver_setup_file file.
The resolver is stopped.

Operator response
 If you want the resolver to use the same
level of monitoring function, issue a MODIFY RESOLVER,REFRESH command.
If not, contact the system programmer.

System programmer response
 If you want the resolver to use the
same level of function, instruct the operator to issue a MODIFY RESOLVER,REFRESH
command.
 If you want the resolver to use a different level
of function, first modify your resolver setup file. If you want the resolver to automatically quiesce unresponsive
name servers, specify the AUTOQUIESCE operand on the UNRESPONSIVETHRESHOLD
resolver setup statement. When the AUTOQUIESCE operand is specified,
the resolver automatically stops sending the DNS queries generated
by an application to unresponsive name servers. The resolver uses
the threshold value specified on the UNRESPONSIVETHRESHOLD resolver
setup statement to determine whether a name server is unresponsive.
If you no longer want the resolver to automatically quiesce unresponsive
name servers, delete the AUTOQUIESCE operand from the UNRESPONSIVETHRESHOLD
resolver setup statement. The resolver continues to monitor the responsiveness
of name servers in your network, but only alerts the network operator
of the unresponsive condition. The resolver continues to send the
DNS queries generated by an application to all name servers.
If you no longer want the resolver to perform any level of monitoring
of  unresponsive name servers, specify the UNRESPONSIVETHRESHOLD(0)
statement in the resolver setup file.

  After you modify the resolver setup file, instruct the operator
to issue the MODIFY RESOLVER,REFRESH,SETUP=setup_file_name command.

User response
 Not applicable.

Problem determination
 In most cases, the resolver will generate
a dump in addition to displaying this message. Contact IBM® Service with the dump information for additional
problem  determination.

Automation
 This message is a good candidate for automation,
if you want to restart the same level of resolver function by using
the MODIFY RESOLVER,REFRESH command.
