Error description
After upgrading to CICSTS4.1 and zOS1.12 we get this: FUNCTION(VERIFY_IP_ADDRESS) GETADDRINFO_ERROR RETURN_VALUE(-1) RETURN_CODE(1) REASON_CODE(78AE1004) and during CICS startup message : 14.13.23 +DFHSO0113 The IP address NN.NNN.NN.NNN cannot be resolved to a host name by Gethostbyname function. CICS is not using the TCP/IP stack specified in the SYSTCPD dataset but instead uses the default TCP/IP stack. This results in /etc/resolv.conf being used in preference to the SYSTCPD DD statement when locating the resolver configuration information. .

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: msgDFHSO0113 issued after upgrading to * * CICS TS 4.2. * **************************************************************** * RECOMMENDATION: * **************************************************************** z/OS is configured with resolver configuration information in /etc/resolv.conf. This configuration uses DNS servers that contain only internal (intranet) addresses. The CICS JCL contains a SYSTCPD DD statement which specifies a dataset member which is a resolver configuration file that uses DNS servers that contain external (internet) addresses. When an application in CICS attempts to connect to a server on the internet a DNS lookup is performed to obtain the IP address. The resolver configuration that gets used is from /etc/resolv.conf so the name is unable to be resolved and message DFHSO0113 gets issued and the request to the remote system will fail. In releases of CICS before CICS TS 4.1 the resolver configuration from the SYSTCPD DD statement would have been used in this situation and the DNS lookup would have been successful.
Problem conclusion
DFHSOIS has been changed to inform the resolver that this is a CICS system and it should use the SYSTCPD DD dataset in preference to /etc/resolv.conf when locating the resolver configuration information. TCP/IP APAR PM46927 is required for this change to be effective.
