z/OS Communications Server: IP Messages Volume 2 (EZB, EZD)
SC27-3655-01

EZD1271E
ADNR CONNECTION TO GWM gwmipaddress IS NO LONGER ACTIVE

Explanation

The automated domain name registration (ADNR) application no longer has a connection to the Global Workload Manager (GWM).

In the message text:
gwmipaddress
The IP address of the GWM. The IP address is specified on the gwm_id parameter of the gwm statement in the ADNR configuration file.

System action

Processing continues. The ADNR application can no longer communicate with the GWM. ADNR will periodically try the connection again. If it succeeds, the eventual action message will be deleted. See the information about automated domain name registration in z/OS Communications Server: IP Configuration Guide for more information.

Operator response

If the GWM application has been stopped, no further actions are needed. When the GWM application is restarted, the ADNR application automatically reconnects to the GWM. If the GWM was not stopped and the reason for the connection attempt failure between the ADNR and GWM application cannot be determined, save the following information:
  • The ADNR log file
  • Any ADNR dump produced when the problem occurred
  • The TCP/IP profile and system log of the TCP/IP stack used by the ADNR application
  • The GWM log file
  • The TCP/IP profile and system log of the TCP/IP stack used by the GWM application

Contact the system programmer.

System programmer response

Verify that routing exists between the IP address used by the ADNR application and the IP address of the GWM that is specified in the message. A route should exist from the ADNR IP address to the GWM IP address, and a route should also exist from the GWM IP address to the ADNR IP address. The IP address used by the ADNR application is found in one of the following places:
  • The IP address is specified on the host_connection_addr parameter of the gwm statement that contains the corresponding gwm_id parameter in the ADNR configuration file.
  • The IP address is displayed in message EZD1263I. This message is issued by the Load Balancing Advisor. Look for this message in the system log for the system on which the Advisor is running, at a time that corresponds approximately to the time at which this ADNR was started.

If routing exists, then check the ADNR and GWM log files for messages corresponding to the time when the connection failed. See the information about diagnosing problems with the automated domain name registration application in z/OS Communications Server: IP Diagnosis Guide. If the reason for the connection loss cannot be determined, contact the IBM® support center after obtaining the supporting TCP/IP, ADNR, and GWM documentation.
