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 on security settings. The -verbose option displays the configuration file name and line number where a configuration variable is defined. Any changes made by condor_config_val will not take effect until condor_reconfig is invoked. It is generally wise to test a new configuration on a single machine to ensure that no syntax or other errors in the configuration have been made before the reconfiguration of many machines. Having bad syntax or invalid configuration settings is a fatal error for Condor daemons, and they will exit. It is far better to discover such a problem on a single machine than to cause all the Condor daemons in the pool to exit. The -set option sets one or more persistent configuration file entries. The string must be a single argument, so enclose it in double quote marks. A string must be of the form "variable = value". Use of the -set option implies the use of configuration variables SETTABLE_ATTRS... (see ), ENABLE_PERSISTENT_CONFIG(see ), and HOSTALLOW... (see ). The -rset option sets one or more runtime configuration file entries. The string must be a single argument, so enclose it in double quote marks. A string must be of the form "variable = value". Use of the -rset option implies the use of configuration variables SETTABLE_ATTRS... (see ), ENABLE_RUNTIME_CONFIG(see ), and HOSTALLOW... (see ). The -unset option changes one or more persistent configuration file entries to their previous value. The -runset option changes one or more runtime configuration file entries to their previous value. The -tilde option displays the path to the Condor home directory. The -owner option displays the owner of the condor_config_val process. The -config option displays the current configuration files in use. The -dump option displays a list of all of the defined macros in the configuration files found by condor_config_val , along with their values. If the -verbose option is supplied 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.

Options

-name machine_name
Query the specified machine's condor_master daemon for its configuration. Does not function together with any of the options: -dump , -config , or -verbose .
-pool centralmanagerhostname[:portnumber]
Use the given central manager and an optional port number to find daemons.
-address <ip:port>
Connect to the given IP address and port number.
-master | -schedd | -startd | -collector | -negotiator
The specific daemon to query. If not specified, the master is the default.

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

Here is a set of examples to show a sequence of operations using condor_config_val . To request the condor_schedd daemon on host perdita to display the value of the MAX_JOBS_RUNNINGconfiguration variable:



   % condor_config_val -name perdita -schedd MAX_JOBS_RUNNING

   500 To request the condor_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
