I do not have domain defined in the bootstrap file. Not sure if sge will ignore the domain specified when I configured admin host and the exec hosts etc.

what about changing the default_domain in the bootstrap file?

Thanks Reuti:
Yes, I have re-configured all admin/exec hosts to the new FQDN and no problem there right now.

Is act_qmaster is the only place qmaster is defined?
Is it possible to keep the server name same and just change the domain part?
So, if I define  qmaster with a new FQDN in host_aliases that could be a work around for now?

you mean all fqdn of the exechosts are already added as adminstrative and exechosts in the qmaster? I did this once, IIRC I first added the future fqdn of the qmaster as administrative host, then shut it down, changed the content of the $SGE_ROOT/default/common/act_qmaster, started it again and removed the old qmaster's fqdn from the list of administrative hosts.

But maybe you can also avoid this and define an entry in $SGE_ROOT/default/common/host_aliases, so that the old name will simply be routed to the new one.
