condor_advertise [-pool centralmanagerhostname[:portname]] [-debug] [-tcp] [-multiple] update-command [classad-filename]
When -multiple is specified, multiple ClassAds may be published. Publishing many ClassAds in a single invocation of condor_advertise is more efficient than invoking condor_advertise once per ClassAd. The ClassAds are expected to be separated by one or more blank lines. When -multiple is not specified, blank lines are ignored (for backward compatibility). It is best not to rely on blank lines being ignored, as this may change in the future.
The update-command may be one of the following strings:
condor_advertise can also be used to invalidate and delete ClassAds currently held by the condor_collector daemon. In this case the update-command will be one of the following strings:
For any of these INVALIDATE commands, the ClassAd in the required file consists of three entries. The file contents will be similar to:
MyType = "Query" TargetType = "Machine" Requirements = Name == "condor.example.com"The definition for MyType is always Query. TargetType is set to the MyType of the ad to be deleted. This MyType is DaemonMaster for the condor_master ClassAd, Machine for the condor_startd ClassAd, Scheduler for the condor_schedd ClassAd, and Negotiator for the condor_negotiator ClassAd. Requirements is an expression evaluated within the context of ads of TargetType. When Requirements evaluates to True, the matching ad is invalidated. A full example is given below.
For each of these attributes, see section 12 for definitions.
For those administrators who do need condor_advertise, the following attributes may be included:
If both of the above are included, the condor_collector will automatically include the following attributes:
Assume that a machine called condor.example.com is turned off, yet its condor_startd ClassAd does not expire for another 20 minutes. To avoid this machine being matched, an administrator chooses to delete the machine's condor_startd ClassAd. Create a file (called remove_file in this example) with the three required attributes:
MyType = "Query" TargetType = "Machine" Requirements = Name == "condor.example.com"
This file is used with the command:
% condor_advertise INVALIDATE_STARTD_ADS remove_file
condor_advertise will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure. Success means that all ClassAds were successfully sent to all condor_collector daemons. When there are multiple ClassAds or multiple condor_collector daemons, it is possible that some but not all publications succeed; in this case, the exit status is 1, indicating failure.
