Re: [Condor-users] FQDN to avoid specific machine(s)

[Michael Lanham <mlanham@xxxxxxxxxx>]

Matt, 

I have gotten perms to do the very thing on our cluster...in particular to advertise JAVA after appropriately configuring each node's config file to point to its java.exe.

I also got the question answer about needing quotes (I do) and not needing a DNS-style trailing period for the FQDN.

Thanks,
Mike

Archives have examples with quotes and without quotes.  I have confirmed with condor_q -l that the machines names are advertising in all lower case, since =!= is case preserving (BTW, pro-ed question: whats the difference between case preserving and case sensitive?).
