Re: [HTCondor-users] Advertising a Windows machine's DSNs

["John (TJ) Knoeller" <johnkn@xxxxxxxxxxx>]

Could you publish the DSN_LIST as a regex that the client then tried to 
match against it's needs?

DSN_NAMES = "MYDBSRV[1-8]"

Requirements = ... && Regexp(TARGET.DSN_NAMES, "MYDBSRV2")

-tj

Since it is possible for these machines to have up to ~2,000 DSNs installed, this seems unwieldy. Another approach is to define a single ClassAd whose value is a delimited list of the installed DSNs.
