Description

Resolution:
========================================================
*** Important: This question/solution applies to Mainframes ONLY.
========================================================

We have to assume you are running on a reasonably up-level z/OS release or the following suggestion will not work as it uses parameters not supported by IBM at lower levels.  You will need to be running a fully customized RESOLVER.

In the TCPIP.DATA (or equivalent) used in the RESOLVER address space, you can add the LOOKUP parameter as follows:

LOOKUP LOCAL DNS

This tells resolver to do a local lookup first, and if it finds a hostname match, use it, otherwise use DNS.

Then, you must create a complete hosts local configuration (ie in /etc or TCPIP.HOSTS.LOCAL followed by MAKESITE) that contains an entry for the local host with the temporary IP address in it, ie:

HOST : 10.101.10.10 : MVS1, mvs1.tibco.com ::::
