Hi all, I do have a follow-up question: When I am specifying hostnames for the execution hosts, admin hosts, etc.; do I need to use the FQDN? Or can I simply use the hostname in order for grid to operate correctly? That is, do I have to use hostname.domain.com (as I am currently doing). Or is it sufficient to simply use “hostname”?

Hi Daniel, Thank you for your reply. From: Daniel Povey <dpo...@gmail.com<mailto:dpo...@gmail.com>> You may have to write a script to do that, but it could be something like for exechost in $(qconf -sel); do qconf -se $exechost | sed s/old_domain_name/new_domain_name/ > tmp qconf -de $exechost qconf -Ae tmp done but you might need to tweak that to get it to work, e.g. get rid of load_values from the tmp file. [Mun] Understood. Since we have a fairly small set of servers currently, I may just update them by hand via “qconf -me <hostname>”; and then address the queues via “qconf -mq <qname>”. Oh, and I just noticed I can modify hostgroups via “qconf -mhgrp @name”. After that I can re-start the daemons and I “should” be good to go, right? Thanks again Daniel.

[Mun] An outage is acceptable; but I'm not sure what is the best/easiest approach to take in order to change the domain names within SGE for all of the servers as well as update the hostgroups and queues. I mean, I know I can delete the hosts and add them back in; and the same for the queue specifications, etc. However, I'm not sure if that is an adequate solution or one that will cause problems for me. I'm also not sure if that is the best approach to take for this task.
