condor_advertise

Send a ClassAd to the condor_collector daemon

Synopsis

condor_advertise [-help $\vert$ -version]

condor_advertise [-pool centralmanagerhostname[:portname]] [-debug] [-tcp] [-multiple] update-command [classad-filename]

Description

condor_advertise sends one or more ClassAds to the condor_collector daemon on the central manager machine. The required argument update-command says what daemon type's ClassAd is to be updated. The optional argument classad-filename is the file from which the ClassAd(s) should be read. If classad-filename is omitted or is the dash character ('-'), then the ClassAd(s) are read from standard input.

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:

UPDATE_STARTD_AD
UPDATE_SCHEDD_AD
UPDATE_MASTER_AD
UPDATE_GATEWAY_AD
UPDATE_CKPT_SRVR_AD
UPDATE_NEGOTIATOR_AD
UPDATE_HAD_AD
UPDATE_AD_GENERIC
UPDATE_SUBMITTOR_AD
UPDATE_COLLECTOR_AD
UPDATE_LICENSE_AD
UPDATE_STORAGE_AD

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:

INVALIDATE_STARTD_ADS
INVALIDATE_SCHEDD_ADS
INVALIDATE_MASTER_ADS
INVALIDATE_GATEWAY_ADS
INVALIDATE_CKPT_SRVR_ADS
INVALIDATE_NEGOTIATOR_ADS
INVALIDATE_HAD_ADS
INVALIDATE_ADS_GENERIC
INVALIDATE_SUBMITTOR_ADS
INVALIDATE_COLLECTOR_ADS
INVALIDATE_LICENSE_ADS
INVALIDATE_STORAGE_ADS

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.

Options

-help
Display usage information
-version
Display version information
-debug
Print debugging information as the command executes.
-multiple
Send more than one ClassAd, where the boundary between ClassAds is one or more blank lines.
-pool centralmanagerhostname[:portname]
Specify a pool by giving the central manager's host name and an optional port number. The default is the COLLECTOR_HOST specified in the configuration file.
-tcp
Use TCP for communication. Without this option, UDP is used.

General Remarks

The job and machine ClassAds are regularly updated. Therefore, the result of condor_advertise is likely to be overwritten in a very short time. It is unlikely that either HTCondor users (those who submit jobs) or administrators will ever have a use for this command. If it is desired to update or set a ClassAd attribute, the condor_config_val command is the proper command to use.

Attributes are defined in Appendix A of the HTCondor manual.

For those administrators who do need condor_advertise, the following attributes may be included:

DaemonStartTime
UpdateSequenceNumber

If both of the above are included, the condor_collector will automatically include the following attributes:

UpdatesTotal
UpdatesLost
UpdatesSequenced
UpdatesHistory
Affected by COLLECTOR_DAEMON_HISTORY_SIZE .

Examples

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 

Exit Status

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.
