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 CONFIG access 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 3.6.1 on
page ![[*]](crossref.png)
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 3.3.5), ENABLE_PERSISTENT_CONFIG (see 3.3.5), and HOSTALLOW... (see 3.3.5).
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 3.3.5), ENABLE_RUNTIME_CONFIG (see 3.3.5), and HOSTALLOW... (see 3.3.5).
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 variable, 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. If the -expand option is given in addition to the -dump option, then variable values in the configuration files are expanded before being printed out.
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.
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_RUNNING configuration 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_RUNNING configuration 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_RUNNING back 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
