condor_checkpoint

send a checkpoint command to jobs running on specified hosts

Synopsis

condor_checkpoint [-help $|$ -version]

condor_checkpoint [-debug] [-pool
centralmanagerhostname[:portnumber]] [-name/SPAN>hostname $|$ hostname $|$ -addr/SPAN>"$<$a.b.c.d:port$>$" $|$ "$<$a.b.c.d:port$>$" $|$ -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 specified 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 condor_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_checkpoint has 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

[-help] Display usage information
[-version] Display version information
[-debug] Causes debugging information to be sent to stderr, based on the value of the configuration variable TOOL_DEBUG
[-pool/SPAN>centralmanagerhostname[:portnumber]] Specify a pool by giving the central manager's host name and an optional port number
[-name/SPAN>hostname] Send the command to a machine identified by hostname
[hostname] Send the command to a machine identified by hostname
[-addr/SPAN>"$<$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/SPAN>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_checkpoint will 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_checkpoint command to a machine within a pool of machines other than the local pool, use the -pool option. 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 command. This command sends the command to a the single machine named cae17 within the pool of machines that has condor.cae.wisc.edu as its central manager:

% condor_checkpoint -pool condor.cae.wisc.edu -name cae17
