Re: [Condor-users] Using Condor WebServices

[Matthew Farrellee <matt@xxxxxxxxxxx>]

I have an idea.

The collector is a "soft cache", meaning it's state is updated  
periodically and if it isn't updated it goes away. Therefore, a  
startd will periodically send a new ad to the collector and that ad  
will overwrite any old ads for the startd. If you directly modify the  
startd's ad with InsertAd your modification will only persist until  
the next time the startd updates its ad. The reason everything works  
when you use condor_config_val is because you are telling the startd  
to send an ad with your modifications.

It's a classic last-writer-wins problem. Your best bet is to actually  
tell a startd to send an ad with your modifications -- use  
condor_config_val.

Is there a particular reason you want to modify a startd ad via the  
WS interface?

Best,


matt
