Description

condor_config_val can be used to quickly see what the current Condor configuration is on any given machine. Given a list of variables, condor_config_val will report what each of these variables is currently set to. If a given variable is not defined, condor_config_val will halt on that variable, and report that it is not defined. By default, condor_config_val looks in the local machine's configuration files in order to evaluate the variables.

condor_config_val can also be used to quickly set configuration variables for a specific daemon on a given machine. Each daemon remembers settings made by condor_config_val . The configuration file is not modified by this command. Persistent settings remain when the daemon is restarted. Runtime settings are lost when the daemon is restarted. In general, modifying a host's configuration with condor_config_val requires the CONFIGaccess level, which is disabled on all hosts by default. Administrators have more fine-grained control over which access levels can modify which settings. See section on page for more details.

NOTE : The changes will not take effect until you perform a condor_reconfig .

NOTE : It is generally wise to test a new configuration on a single machine to ensure you have no syntax or other errors in the configuration before you reconfigure many machines. Having bad syntax or invalid configuration settings is a fatal error for Condor daemons, and they will exit. Far better to discover such a problem on a single machine than to cause all the Condor daemons in your pool to exit.

Options

-name machine_name: Query the specified machine's condor_master daemon for its configuration.
-pool centralmanagerhostname[:portnumber]: Use the given central manager and an optional port number to find daemons.
-address <ip:port>: Connect to the given ip/port.
-master | -schedd | -startd | -collector | -negotiator: The daemon to query (if not specified, master is default).
-set string...: Set a persistent config file entry. The string must be a single argument, so you should enclose it in double quotes. The string must be of the form ``variable = value''.
-rset string...: Set a runtime config file entry. See the description for -set for details about the string to use.
-unset variable...: Unset a persistent config file variable.
-runset variable...: Unset a runtime config file variable.
-tilde: Return the path to the Condor home directory.
-owner: Return the owner of the condor_config_val process.
-config: Print the current configuration files in use.
-dump: Returns a list of all of the defined macros in the configuration files found by condor_config_val , along with their values. If the -verbose is suppled as well, then the specific configuration file which defined each macro, along with the line number of its definition is also printed. NOTE : The output of this argument is likely to change in a future revision of Condor.
-verbose variable...: Returns the configuration file name and line number where a configuration variable is defined.
variable...: The variables to query.

Exit Status

condor_config_val will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.

Examples

To request the schedd daemon on host perdita to give the value of the MAX_JOBS_RUNNINGconfiguration variable:: % condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
500
To request the schedd daemon on host perdita to set the value of the MAX_JOBS_RUNNINGconfiguration variable to the value 10.: % condor_config_val -name perdita -schedd -set "MAX_JOBS_RUNNING =
10": Successfully set configuration "MAX_JOBS_RUNNING = 10" on
schedd perdita.cs.wisc.edu <128.105.73.32:52067>.
A command that will implement the change just set in the previous example.: % condor_reconfig -schedd perdita
Sent "Reconfig" command to schedd perdita.cs.wisc.edu
A re-check of the configuration variable reflects the change implemented:: % condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
10
To set the configuration variable MAX_JOBS_RUNNINGback to what it was before the command to set it to 10:: % condor_config_val -name perdita -schedd -unset MAX_JOBS_RUNNING
Successfully unset configuration "MAX_JOBS_RUNNING" on
schedd perdita.cs.wisc.edu <128.105.73.32:52067>.
A command that will implement the change just set in the previous example.: % condor_reconfig -schedd perdita
Sent "Reconfig" command to schedd perdita.cs.wisc.edu
A re-check of the configuration variable reflects that variable has gone back to is value before initial set of the variable:: % condor_config_val -name perdita -schedd MAX_JOBS_RUNNING
500
