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 Condor 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.

For each of these attributes, see section 10 for definitions.

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

Also see COLLECTOR_DAEMON_HISTORY_SIZE in section 3.3.16.

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.
