condor_checkpoint(1) General Commands Manual condor_checkpoint(1)
Name
condor_checkpoint send - a checkpoint command to jobs running on specified hosts
Synopsis
condor_checkpoint [-help -version]
condor_checkpoint[-debug] [-pool centralmanagerhostname[:portnumber]] [-name hostnamehostname-addr "<a.b.c.d:port>""<a.b.c.d:port>"-con-
straint expression-all]
Description
condor_checkpoint sends a checkpoint command to a set of machines within a single pool. This causes the startd daemon on each of the speci-
fied machines to take a checkpoint of any running job that is executing under the standard universe. The job is temporarily stopped, a
checkpoint is taken, and then the job continues. If no machine is specified, then the command is sent to the machine that issued the con-
dor_checkpoint command.
The command sent is a periodic checkpoint. The job will take a checkpoint, but then the job will immediately continue running after the
checkpoint is completed. condor_vacate, on the other hand, will result in the job exiting (vacating) after it produces a checkpoint.
If the job being checkpointed is running under the standard universe, the job produces a checkpoint and then continues running on the same
machine. If the job is running under another universe, or if there is currently no Condor job running on that host, then condor_check-
pointhas no effect.
There is generally no need for the user or administrator to explicitly run condor_checkpoint. Taking checkpoints of running Condor jobs is
handled automatically following the policies stated in the configuration files.
Options

-debug
Causes debugging information to be sent to stderr , based on the value of the configuration variable TOOL_DEBUG
-pool centralmanagerhostname[:portnumber]
Specify a pool by giving the central manager's host name and an optional port number
-name hostname
Send the command to a machine identified by hostname
hostname
Send the command to a machine identified by hostname
-addr <a.b.c.d:port>
Send the command to a machine's master located at "<a.b.c.d:port>"
<a.b.c.d:port>
Send the command to a machine located at "<a.b.c.d:port>"
-constraint expression
Apply this command only to machines matching the given ClassAd expression
-all
Send the command to all machines in the pool
Exit Status
condor_checkpointwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
Examples
To send a condor_checkpoint command to two named machines:
% condor_checkpoint robin cardinal
To send the condor_checkpointcommand to a machine within a pool of machines other than the local pool, use the -pooloption. The argument is
the name of the central manager for the pool. Note that one or more machines within the pool must be specified as the targets for the com-
mand. This command sends the command to a the single machine named cae17within the pool of machines that has condor.cae.wisc.eduas its cen-
tral manager:
% condor_checkpoint -pool condor.cae.wisc.edu -name cae17
