On Mainframes, how do we force RVD to do a local lookup and not DNS lookup?Usually RVD/RVRD uses DNS to obtain IP address of the local host.But is there a way to tell RV to first do a local lookup?

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 ::::
