SYNOPSIS

12       condor_advertise [-help | -version ]
13
14       condor_advertise  [-pool  centralmanagerhostname[:portname]]  [-debug ]
15       [-tcp ] [-udp ] [-multiple ] [update-command [classad-filename]]
16

DESCRIPTION

18       condor_advertise sends one or more  ClassAds  to  the  condor_collector
19       daemon  on  the  central  manager  machine.  The  optional argument up‐
20       date-command says what daemon type's ClassAd is to be updated; if it is
21       absent,  it  assumed to be the update command corresponding to the type
22       of the (first) ClassAd. The optional argument classad-filename  is  the
23       file  from which the ClassAd(s) should be read.  If classad-filename is
24       omitted or is the dash character ('-'), then the  ClassAd(s)  are  read
25       from standard input. You must specify update-command if you do not want
26       to read from standard input.
27
28       When -multiple is specified, multiple ClassAds may be published.   Pub‐
29       lishing  many  ClassAds  in  a single invocation of condor_advertise is
30       more efficient than invoking condor_advertise once  per  ClassAd.   The
31       ClassAds are expected to be separated by one or more blank lines.  When
32       -multiple is not specified, blank lines are ignored (for backward  com‐
33       patibility).  It  is  best not to rely on blank lines being ignored, as
34       this may change in the future.
35
36       The update-command may be one of the following strings:
37          UPDATE_STARTD_AD UPDATE_SCHEDD_AD UPDATE_MASTER_AD UPDATE_GATEWAY_AD
38          UPDATE_CKPT_SRVR_AD     UPDATE_NEGOTIATOR_AD    UPDATE_HAD_AD    UP‐
39          DATE_AD_GENERIC UPDATE_SUBMITTOR_AD  UPDATE_COLLECTOR_AD  UPDATE_LI‐
40          CENSE_AD UPDATE_STORAGE_AD
41
42       condor_advertise  can  also  be  used to invalidate and delete ClassAds
43       currently held by the condor_collector daemon. In  this  case  the  up‐
44       date-command will be one of the following strings:
45          INVALIDATE_STARTD_ADS   INVALIDATE_SCHEDD_ADS  INVALIDATE_MASTER_ADS
46          INVALIDATE_GATEWAY_ADS INVALIDATE_CKPT_SRVR_ADS  INVALIDATE_NEGOTIA‐
47          TOR_ADS INVALIDATE_HAD_ADS INVALIDATE_ADS_GENERIC INVALIDATE_SUBMIT‐
48          TOR_ADS  INVALIDATE_COLLECTOR_ADS   INVALIDATE_LICENSE_ADS   INVALI‐
49          DATE_STORAGE_ADS
50
51       For  any of these INVALIDATE commands, the ClassAd in the required file
52       consists of three entries. The file contents will be similar to:
53
54          MyType = "Query"
55          TargetType = "Machine"
56          Requirements = Name == "condor.example.com"
57
58       The definition for MyType is always Query. TargetType is set to the My‐
59       Type  of the ad to be deleted. This MyType is DaemonMaster for the con‐
60       dor_master ClassAd, Machine for the  condor_startd  ClassAd,  Scheduler
61       for the condor_schedd ClassAd, and Negotiator for the condor_negotiator
62       ClassAd.
63
64       Requirements is an expression evaluated within the context  of  ads  of
65       TargetType. When Requirements evaluates to True, the matching ad is in‐
66       validated. A full example is given below.

OPTIONS

69          -help  Display usage information
70
71          -version
72                 Display version information
73
74          -debug Print debugging information as the command executes.
75
76          -multiple
77                 Send more than one ClassAd, where the boundary between  Clas‐
78                 sAds is one or more blank lines.
79
80          -pool centralmanagerhostname[:portname]
81                 Specify  a pool by giving the central manager's host name and
82                 an optional port number. The default  is  the  COLLECTOR_HOST
83                 specified in the configuration file.
84
85          -tcp   Use  TCP for communication. Used by default if UPDATE_COLLEC‐
86                 TOR_WITH_TCP is true.
87
88          -udp   Use UDP for communication.
89

GENERAL REMARKS

91       The job and machine ClassAds are regularly updated. Therefore, the  re‐
92       sult  of  condor_advertise  is likely to be overwritten in a very short
93       time. It is unlikely that either HTCondor users (those who submit jobs)
94       or  administrators  will ever have a use for this command. If it is de‐
95       sired to update or set a ClassAd attribute, the condor_config_val  com‐
96       mand is the proper command to use.
97
98       Attributes are defined in Appendix A of the HTCondor manual.
99
100       For  those  administrators  who do need condor_advertise, the following
101       attributes may be included:
102          DaemonStartTime UpdateSequenceNumber
103
104       If both of the above are included, the condor_collector will  automati‐
105       cally include the following attributes:
106          UpdatesTotal UpdatesLost UpdatesSequenced UpdatesHistory
107              Affected by COLLECTOR_DAEMON_HISTORY_SIZE  .
108

EXAMPLES

110       Assume  that a machine called condor.example.com is turned off, yet its
111       condor_startd ClassAd does not expire for another 20 minutes. To  avoid
112       this  machine being matched, an administrator chooses to delete the ma‐
113       chine's condor_startd ClassAd. Create a  file  (called  remove_file  in
114       this example) with the three required attributes:
115
116          MyType = "Query"
117          TargetType = "Machine"
118          Requirements = Name == "condor.example.com"
119
120       This file is used with the command:
121
122          % condor_advertise INVALIDATE_STARTD_ADS remove_file
123

EXIT STATUS

125       condor_advertise  will  exit  with a status value of 0 (zero) upon suc‐
126       cess, and it will exit with the value 1  (one)  upon  failure.  Success
127       means  that all ClassAds were successfully sent to all condor_collector
128       daemons. When there are multiple ClassAds or multiple  condor_collector
129       daemons,  it is possible that some but not all publications succeed; in
130       this case, the exit status is 1, indicating failure.
